bootAble

Contents

1. Introduction

2. Highlights

A few highlights of the script:

• Can be used to create bootable CDs and maintenance partitions (and thus can be seen as a replacement of bootOS2);
• Both floppy-emulation and  no-floppy-emulation boot methods supported;
  
• Easy configuration via configuration files (almost everything is configurable);
• WPS (VGA and gengradd) or command-line boot;
• Support for FAT, FAT32, HPFS, HPFS386, NTFS, JFS, CDFS, UDF, and LVM;
• Support for IDE, SCSI, USB, Mouse, Serial port, and Parallel port;
• Support for Unicode;
• Support for REXX;
• Support for basic TCP/IP networking, including DHCP;
• Support for NETBIOS and NETBIOS over TCP/IP protocols (protocols only, no peer);
• Support for Roman Stangl's CD Boot Menu;
• Use of DANI or default drivers;
• Use of JJSCDROM or default drivers;
• Support for RSJ or cdrecord/mkisofs (both original and '2' versions supported);
• Small disk footprint; less than 5MB for the command-line version;
• Can make use of LXLITE to make disk footprint even less;
• And much, much more...

Default settings for file system and driver support are mostly retrieved from the current system (in case of SCSI, you will need to tell bootAble the drivers to use). Adapting these defaults is done by creating a configuration file with the necessary settings.
When creating a bootable CD, the script assumes you use RSJ for burning CDs and that you have already attached the CD-R(W). Instructions for using this script with cdrecord and mkisofs are included.

3. Installation

The simplest way to install bootAble is is to copy all files from the bootAble archive to directory on the PATH or a specific directory (if you use a specific directory, just make sure you run bootAble from that location).
To locate files, bootAble first looks at the specified location (or current directory if no path is given), if the specified file is not found, bootAble searches the paths as specified in the SEARCHPATH setting. By default the SEARCHPATH is made up of \os2\boot on the boot drive, followed by the LIBPATH, PATH, DPATH, HELP, BOOKSHELF, and \psfonts on the boot drive. Note: When specifying files with wildcards, the SEARCHPATH is not searched.

3.1. bootAble Files

3.4. Other files and applications

4. Syntax

The command syntax is as follows:

bootAble [/v <verbose>] [<configuration file>|/@<configuration-list-file>...]

The optional arguments are the verbosity level and one or more configuration files. These configuration files are used to override the defaults as specified in the file bootAble.cfg. The special form /@configuration-list-file causes the content of the configuration list file to be used to list additional configuration files. E.g. if the file myCfg.lst contains the lines

The command

would have exactly the same result as

Notes:

• Configuration files as well as configuration list files are searched for on the SEARCHPATH (by default os2\boot on the boot drive followed by LIBPATH, PATH, DPATH, HELP, and BOOKSHELF, and \psfonts on the boot drive);
• As a general rule you should specify your bootAble.myCfg as first configuration file on the command-line.  This to make sure your settings will be used instead of the (global) defaults;
  
• You only need to specify configuration options/variables which override the defaults!

5. Creating a bootable CD

Here are a few easy steps for creating a bootable CD (please also see Debugging for some debugging info and tips):

1. Download and install all required files;
2. Read through the configuration file bootAble.cfg. All default settings for the script are done via this file. The options are all commented. Work through them top to bottom, most likely you will only need/want to change a few of the 'basic' ones. You'll probably not going to need to bother with the 'advanced' ones (unless you know what you are doing...);
   Please note: When configuring bootAble you can/should leave the generic defaults file bootAble.cfg alone and create your own configuration file(s). A configuration file only needs to contain lines for configuration options/variables overriding the defaults! See for example the supplied configurations files bootAble.wps, bootAble.maintenance, etc.
   
3. Create a bootAble.myCfg where you change the default options to match your needs (an example .myCfg as well as other example configuration files are included):
1. You probably need to change directories/drives to match your setup;
2. You probably want to specify BOOTMESSAGES='YES', and PAUSEBEFOREBOOTIMAGE='YES' (already done in the sample bootAble.myCfg);
3. You probably also want to specify EXTRACONFIGSYS='' as the default will cause the screen to go to 80x50 mode, causing you to loose all boot progress messages (already done in the sample bootAble.myCfg)
4. If you have SCSI, set the SCSI option and specify the device driver for your card(s). You may need to set the TWODISKBOOT option, make use of the MEMDISK boot method or turn-off some other options if the driver(s) is/are a really big;
4. This should cover most cases, time to create the first boot image (instructions are for using RSJ, see below for necessary adaptations for using cdrecord/mkisofs):
1. Insert an empty CD-R(W) in your burner. I would really suggest to use CD-RW media; you are probably going to run this script a lot of times to get things the way you want. I know CD-Rs are dirt cheap, but please give the environment a break and what would you do with tons of coasters? (Yeah, you can microwave them for great effects but that becomes boring after a while...);
2. Attach the CD-R(W) (cdattach w:). If it's a CD-RW you can erase it as well (cdwfmt w: /erase).  You can also add the lines RSJATTACHCD='YES' and ERASECD='YES' to your bootAble.myCfg to let bootAble perform this step automatically;
3. Run the script with your configuration file, specifying an adequate verbose level (e.g., bootAble /v 67 bootAble.myCfg);
4. Put additional files on the CD if you like;
5. Burn the CD (cdattach w: -s).  Or let bootAble do this automatically as well (just add the line AUTOBURNCD='YES' to your bootAble.myCfg);
5. Test it.

That's all! Now you probably want to play a bit with the numerous other options :-)

5.1 Using mkisofs+cdrecord instead of RSJ

When using mkisofs and cdrecord, change the configuration variable WRITERDRIVE to the path you are going to build the CD in and set the option CDRECORD to 'YES'. The script is now ready to be used for mkisofs/cdrecord. Just one more thing needs to be done after running the script; instead of creating a normal ISO image for burning by cdrecord, you need to specify the correct image file to be used for booting (-b option to mkisofs). For normal floppy emulation booting, this is the OSBOOT.IMG in the root of the CD, for MEMDISK bootAble CDs, this is the CDLOADER.BIN in the BOOTIMGS directory (don't forget the -no-emul-boot option!). Remember that mkisofs is case sensitive so use the correct case when specifying filenames.
You can also let bootAble create a command file which contains the necessary mkisofs and cdrecord commands, simply specify CDRECORDBURNCMD='YES' and tweak the command options and file locations (CDRECORDMKISOFSEXE, CDRECORDMKISOFSOPTIONS, CDRECORDEXE, and CDRECORDEXEOPTIONS). The burnCD command is created in the current directory, burnCD creates the iso image in the TEMP directory, so make sure there is enough room.
If you feel confident, you can let bootAble erase (ERASECD='YES') and burn the CD automatically (AUTOBURNCD='YES').

6. Creating a maintenance partition

When creating a maintenance partition, follow the instructions found in the section describing the creation of a bootable CD (skip the specific steps involving CD creation; 4a, 4b, and 4c). When adapting the configuration file, additionally specify CREATEBOOTCD='NO' and point WRITERDRIVE to the maintenance partition (see bootAble.maintenance for an example); and run the script with these additional settings (e.g., bootAble bootAble.myCfg bootAble.maintenance).
Though it is advisable to format the maintenance partition (creating files like the config.sys may not work correctly otherwise), this is not the default behaviour of bootAble. This is done to prevent accidental data loss of the maintenance partition. With FORMATMAINTENANCE='NO', the user is asked a question to format the maintenance partition. If you do not want to get this question, specify FORMATMAINTENANCE='YES' in your bootAble.myCfg.

7.1 Test runs

7.2 Errors generated by the script

• To get progress messages and error output of external commands, specify VERBOSE=65 (64+1), this is the default;
  
• To get progress messages only, specify VERBOSE=1;
• For progress messages and a list of files copied, use VERBOSE=3 (2+1);
• To also get error output of extrernal commands, use VERBOSE=67 (64+2+1);
• For configuration file parsing information (use with care; creates lots of output), add 4 to your VERBOSE setting;
• To get all output, use VERBOSE=207 (or 255 to be on the safe side for when I add verbose levels  ;-) ).

Version History

v3.2 (27/03/2004)

• Added option for allowing access to >16MB early in boot process, a recent kernel is required for this to work (EARLYMEMINIT);
  
• The WPS and the WPS Application files can now also reside on the image (WPSDESTINATION, WPSAPPSDESTINATION);
  Note: Requires EARLYMEMINIT='YES' (done automatically).
• Renamed lvmrefresh.cmd and lvmrefresh.ico to lvmrfrsh.* to comply to 8.3 naming convention;
• Doug Bissett contributed configuration files for adding Back Again 2000 support (bootAble.ba2kws and bootAble.ba2kwsRC);
• Renamed bootAble.ttf to bootAble.font to prevent interpretation of the file as a true type font by the OS/2/eCS GUI;
  
• VERBOSE is now 65 by default (i.e., progress messages and error output of external commands);
  
• Added ability to automatically burn the CD (AUTOBURNCD, RSJATTACHCD, ERASECD, CDRECORDERASEOPTION);
• Improved defaults value determination for CDROMDRIVE and WRITERDRIVE (see bootAble.cfg for the new defaults);
• The values of EXTRACONFIGSYS, STARTUPCMD and EXTRACREATEFILECONTENT.n are parsed for $$ and %% constructs before they are written to file.  This means that variables/functions are determined at the moment their final value is known (i.e., after processing all configuration files), see bootAble.norman for example usage;
  
• Added note on location of bootAble.myCfg on the command-line (i.e., it should generally be the first configuration file on the command-line, see also Syntax section);
  
• Corrected default setting for USBCDROM and USBSTORAGE;
• Corrected option finding for ATAPI basedev (if you used daniatapi and had both the daniatap.flt and daniatapi.flt files on the system, bootAble could fail to pick up the options);
  
• Corrected paths to cdloader.bin in burnCD.cmd;
• burnCD.cmd now burns the CD without having to create an iso image file first;
• Removed unnecessary options to mkisofs and cdrecord commands;
• Enhanced bootAble.wps so that it does not override previous settings for display resolution etc.;
  
• Corrected startup directory of the dfsee and norman anti virus objects;
• The SWAPPATH line is not aded to the config.sys file anymore when swapping is not enabled (e.g., on a boot CD using the floppy emulation boot method);
  
• Added check for existence of required (non standard) executables;
  
• Corrected a syntax error in bootAble.norman (sorry Doug...);
• At boot, the \OS2 directory on the MEMDISK/RAMDISK now only gets created when necessary;
  
• Unicode keyboard setting should now always default to the correct keyboard layout based on the KEYB setting (UNIKEYB);
• Spelling corrections in documentation.

v3.1a (10/03/2004)

• Corrected unicode keyboard setting for german (GR) keyboard layout, now de.kbl file is used (thank you Veit Kannegieser);
• Corrected syntax error in script (noticeable when using object rexx or the hpfs386 file system, thanks again, Veit Kannegieser).

v3.1 (09/03/2004)

• IMPORTANT: Renamed ADDITIONALCFG to EXTRACONFIGSYS for consistency, check your own configuration files for the use of ADDITIONALCFG settings and change these to EXTRACONFIGSYS;
• bootAble now determines defaults for almost all settings from the config.sys file, meaning your bootAble.myCfg can now almost be empty except where your bootAble CD (or maintenance partition) should differ from the running system, or where you need to specify your SCSI card(s) (see bootAble.cfg and bootAble.myCfg for details);
  
• You can now specify to include more files on the boot image instead of the CD. Due to space constraints, this is probably only useful when using the memdisk boot CD method (OS2APPSDESTINATION, REXXDESTINATION, NETWORKINGDESTINATION, EXTRAFILESDESTINATION, EXTRADLLFILESDESTINATION, EXTRADEVICEDESTINATION, EXTRADIRECTORYDESTINATION.x, EXTRACREATEFILEDESTINATION.x);
• Added option to create a cloneCD command to clone a CD to a maintenance partition using exactly the same options as were used for creating the bootAble CD (CREATECLONDECD and CREATECLONECDDRIVE, CREATECLONECDVERBOSE, CREATECLONECDRAMDISK, CREATECLONECDREMOVEROFLAG, CREATECLONECDDIRECTORY);
  Note: due to FAT filename constraints, the cloneCD command always gets created on the CD.
  
• When using cdrecord, added an option to create a burnCD command (Doug Bissett, thanks for the hints) which can be used to create and write an iso image of the bootAble CD (CDRECORDBURNCMD and other options, see section Using cdrecord+mkisofs instead of RSJ of this document for more info);
  
• Added ability to add a ramdisk to a memdisk bootAble CD. If added, the ramdisk (instead of the memdisk) is used for the temp directory, desktop, etc. The advantage is that the ramdisk is an HPFS-like drive and not a FAT drive, allowing for long file names etc. To support this feature, a new setting has been introduced to specify the drive letter of the memdisk (MEMDISKDRIVE);
  
• Added ability to specify a list-file at all locations where a list of files is expected. The content of this file is then inserted in the file list (see syntax section of this document for an example);
• Instead of a fixed size, you can now also specify the minimum amount of free space on the memdisk boot image by prefixing the MEMDISKSIZE string with a + sign.The default is now to leave approximately 2MB of free space (5MB in case of a WPS system without RAMDISK);
  
• Added PSFONTS directory on the boot drive to the SEARCHPATH by default;
  
• Now cleaning-up unnecessary files on the memdisk boot image (e.g., the tar files), the freed-up space is taken into account when determining the MEMDISKSIZE;
  
• Doug Bissett enhanced bootAble.norman, the log file is now automatically erased after viewing to save space;
• Doug Bissett contributed bootAble.dfsee to add dfsee to your maintenance partition/bootAble CD;
• Added bootAble logo to no floppy emulation boot;
  
• When creating a maintenance partition with FORMATMAINTENANCE not set, the user is now asked to format the partition;
• Added option to set the DHCP server timeout (TCPIPDHCPTIMEOUT);
• Added fdiskpm.exe for non-lvm WPS systems;
• Added objects for FDiskPM/LVM in the setup folder;
• Added icons to LVM and Refresh Removable Media objects;
• Added verbose level 8 to show INI rc file parsing;
• When using the EXTRADIRECTORYADDTOPATHS setting, directories are now only added once to the specified path(s);
  
• A temp directory is now also created on a maintenance partition and not only when a ramdisk or memdisk was loaded;
• Added ability to insert the result of a piece of rexx code within ini files ($$@<rexx-code>$$, see bootAble.pmdll and bootAblefor.usbres for examples);
• Introduced new function to determine the destination drive, mostly for use within ini file definitions (destinationDrive, see bootAble.pmdll and bootAblefor.usbres for examples);
• Added more config.sys information retrieval functions (configSysContains, configSysCount, configSysOptions);
  
• Added option to enable the removal of the Read Only flag when copying files (REMOVEROFLAG);
• The savedskf.exe command does not need to be in the path anymore, you can now specify its location via the SAVEDSKFEXE setting;
  
• HPFS386 files are now found via the searchpath as well;
  
• Enhanced bootAble.emxrt and bootAble.acrobat, by default they should now be able to correctly find the application root in almost all cases;
• Corrected bootAble.4os2 (4os2.ini got created in the wrong directory);
• Progress messages now more consistently (and correctly) indicate the destination (e.g., Boot Image, CD, or Maintenance Partition);
• Rewrote some of the sections in this document to clarify things better (I hope);
  
• Moved unicode.sys before all IFS drivers (where it should be...).

v3.0a (23/02/2004)

• Corrected bugs in bootAble.norman, thank you Doug Bissett! (bootAble.norman and bootAble.normanRC);
• Corrections to documentation on small keyboard.dcp, added note on smaller viotbl.dcp;
  
• No more ea stripping in internal sCopyFile function anymore, saves a little processing time.
  

v3.0 (22/02/2004)

• Added support for the no floppy emulation boot (memdisk) by Veit Kannegieser.Not only does this allow bootAble to operate in many more situations, but booting will be slightly faster and the 2.88 floppy disk space restriction is lifted allowing for many more configurations to be booted from CD;
• Added configuration files for PMdll and USB resource utilities (bootAble.pmdll and bootAble.usbres);
  
• Added preliminary True Type and UniFont support (bootAble.ttf);
• Changed way ini RC files get processed, you can now override previous entries (set the corresponding EXTRAxxxxINIRCFILEUPDATE.x to 'YES').  Furthermore. the EXTRAUSERINI and EXTRASYSINI settings are processed last and can be used to override any entry (see bootAble.myCfg for examples);
• Ini RC files should now only contain the body of a makeini file (i.e., the "<application>" "<key>" <value> triplet, see bootAble.Urc etc. for details);
• Added low-level syntax checking on ini RC files;
  
• Added configuration option for adding OS2SCSI.DMD driver (SCSIDMD, enabled by default if you're adding SCSI support);
  
• Added configuration option for copying the config.sys of the boot image to the root of the CD (COPYCONFIGSYS, disabled by default);
• Added function to retreive values from the config.sys file (getFromConfigSys);
• Added configuration option to specify the name of the config.sys file to use in getFromConfigSys, globally initialised to the config.sys in the root of your boot drive (CONFIGSYSFILE);
• More variables now automaitcally get the correct defaults based on the host system (e.g., RESERVEDRIVELETTER, CDROMDRIVE, VIRTUALDRIVE, SHELLPROMPT, COUNTRY, CODEPAGE, KEYBOARD, UNICODE, UNILANG, UNICP, LVM);
  
• The SEARCHPATH variable is now globally initialised to the value of os2\boot on the boot drive, LIBPATH, PATH, DPATH, HELP, and BOOKSHELF, greatly reducing the need for specifying full file paths in the configuration files (just make sure the correct files are first on the SEARCHPATH!);
• Removed the SMALLKEYBOARDDCP option.If you now want to use a different keyboard.dcp (or viotbl.dcp for that matter) file, simply make sure it is located somewhere on the SEARCHPATH before the original;
  
• Disabled USB support by default (USBxxx);
  
• Added ini RC file option to allow inclusion of a line if an option is not set (%%!<optionname>%%)
  
• Applications now get installed into \OS2\APPS instead of root directory (bootAble.acrobat, etc.);
• Adopted 4os2 support and made it independent of the WPS setting (icon and inf file always copied), furthermore allowed for a destination directory to be set (bootAble.4os2);
  
• Added section on debugging to this document;
• You can now use the /v command-line argument to specify the value of VERBOSE from the command-line (usage: bootAble [/v <verbose>] [<config file>...]);
• You can now download the SIO2K Patch file from my website (kindly provided by the author, Veit Kannegieser);
• Improved PMView support (2.x and 3.x supported), now copying only required files and, thanks to Alfredo Fernández Díaz, also added pmvddrop support (bootAble.pmview);
• The RESERVEDRIVELETTER option is now allowed to be empty;
• Swapping is now enabled when booting from a maintenance partition or a MEMDISK enabled boot;
• Files are now copied to the destination slighly faster (i.e., not always via temp anymore);
  
• Corrected bug where you couldn't copy extra files to the root of a CD when using cdrecord or testing;
• Corrected initial font settings of WPS (now correctly using warpsans);
• Adaptations for the latest newview versions (newview.exe is required);
• Renamed bootAble.PMVrc and bootAble.Xrc to bootAble.pmviewRC and bootAble.xwpRC;
  
• Removed progress message about ignoring already created directories.

v2.19 (25/01/2004)

• Added configuration file for PMView (bootAble.pmview and bootAble.PMVrc);
  
• Changed application configuration files so that you can now simply specify paths (e.g., the application root) in your bootAble.myCfg without having to change the application configuration file itself (see the files bootAble.myCfg, bootAble.4os2, bootAble.acrobat, etc., for examples);
  
• Improved setting application root of some of the applications, these now make use of entries in the ini files (see bootAble.pmview and bootAble.xwp for examples);
• Path/file specifications can now have double backslahes, the script does not fail on this anymore;
  
• Added function defaultIfNotSet to set a variable to a default value if not already set;
• Added function getFromIni to return the text porting of an ini entry (stripping off the trailing 0 delimiter);
• Added a verbosity level to help debug syntax errors in configuration files (VERBOSE);
  
• Changed behaviour of the VERBOSE setting, it is now a binary mask so you have more control over the output;
  
• Added global initialisation of OSBOOTDRIVE with sysBootDrive();
• Added global initialisation for EXTRADEVICE, EXTRABASEDEV, etc. settings, no need to default these anymore in your own configuration files;
  
• Added option for PROTECTONLY setting (default is 'YES');
• Added missing option for specifying the use of the DANI DASD driver instead of the IBM version (DANIDASD), Note: only to be used on non-lvm systems!;
  
• Added sample pmview configuration file (bootAble.pmview);
• Corrected bug with multipe extra ini rc files (only the first rc file got included);
  
• Corrected reference to boot image (osboot.img) in the cdrecord section of this document.

v2.18 (23/12/2003)

• Thanks to Alfredo Fernández Díaz, I've now finally added XWorkplace support (see bootAble.xwp and bootAble.Xrc files).
  XWorkplace can be altered to support additional languages, currently German and Spanish (partial support) are included (see bootAble.xwp_DE and bootAble.xwp_ES for details);
  
• Added ability to enter hexadecimal values in the INI RC files (precede unquoted hexadecimal string by 0x);
• Added ability to specify additional user en system INI RC files (EXTRAUSERINIRCFILES and EXTRASYSINIRCFILES);
• Added advanced option for specifying AUTOSTART directive;
  
• Added option to add EXIT statement to created startup.cmd file (STARTUPCMDEXIT, on by default);
• Added option to update DHCP server with hostname (TCPIPDHCPUPDATEHOST, off by default);
• Changed defeult behaviour of 4OS2 command shell icons to open a new window (bootAble.4os2);
  
• Device driver DOS.SYS now added (actually a required file).
  

v2.17a (21/12/2003)

• Minor corections to bootable.norman configuration file by Doug Bissett.

v2.17 (19/12/2003)

• Support for NTFS version 1.07 (added ntfschk.exe and changed file locations);
• Correction for Newview (ibmhmgr.dll and newview.inf added if found);
• Updated bootable.norman configuration file made by Doug Bissett;
• Settings which typically reside in multiple configuration files (like EXTRADIRECTORIES, EXTRAFILES, etc.) now show the use of varValue in bootAble.cfg to ease adaptation in home made configuration files;
  
• Changed default for formatting the maintenance partition to NO to prevent accidental data loss if the wrong choises have been made (FORMATMAINTENANCE);
  
• Progress message for creating extra files only shown when actually creating extra files.
  

v2.16 (09/07/2003)

• Added SIO and SIO2K serial port driver support (SIOSERIALPORT, SIO2KSERIALPORT, disabled by default);
  
• Added ability to specify content of files to be placed on the CD (EXTRACREATEFILES, EXTRACREATEFILEDIRECTORY.n, EXTRACREATEFILENAME.n, EXTRACREATEFILECONTENT.n), see bootAble.4os2 for an example;
  
• Added NTFS support (NTFS, disabled by default);
• Added sample configuration file for adding the 4OS/2 command shell environment (bootAble.4os2);
• The PPZIP device is not enabled by default anymore;
• Minor eCS 1.1 adjustments (file locations have changed).

v2.15 (16/03/2003)

• Corrected fdisk.exe into fdisk.com when creating a non LVM system;
• The parallel port driver (print01.sys) and aspi driver (os2aspi.dmd) are basedevs, not devices;

• Added ability to recurse directories when specifying extra directories (EXTRADIRECTORYRECURSE.n), see bootAble.acrobat for an example;
  
• Corrected path handling when HPFS386 support was enabled.

v2.12 (20/10/2002)

• Added NETBIOS and NETBIOS over TCP/IP protocol support (NETBIOS and NETBIOSTCPIP, disabled by default);
  Note: Only the protocols themselves are supported, PEER functionality, for instance, is not provided.
• Added option to clean-out cdrecord image directory (pointed to by WRITERDRIVE) prior to adding bootable files and directories (CDRECORDCLEANDIR, disabled by default);

• Improved DHCP support; nameserver can now also be specified by the server dynamically (requires RAMDISK support on a bootAble CD),
• DHCP Client Monitor gets added when DHCP is enabled (WPS),
  
• Improved TCP/IP version 4.31 support; the 4.31 DHCP client required some additional DLLs, these will now be added when TCP/IP 4.31 is specified (TCPIP431, default).
• Additional DEVICE drivers can now be specified similar to how extra BASEDEV drivers were specified (EXTRADEVICE, EXTRADEVICEFILE.n,EXTRADEVICEOPTIONS.n).

• Removed second setting of displaytype and help-path when WPS support was enabled;
• Rewrote installation instructions and merged with obtaining required files section.
  

v2.11 (30/09/2002)

• Added DHCP support (TCPIPDHCP);
  
• Fixed bug in bootAble.extra (missing quotes);
• Fixed bug in handling of extra directories, sometimes ',1' was added to the directory name.
  

v2.10 (29/09/2002)

• You can now specify a search path (SEARCHPATH) where files will be searched for in addition to the location specified (by default this is set to the DPATH). This allows for adding components to a bootable CD/maintenance partition which have not (yet) been installed on your system (or reside in a completely different location from the deafult); just add the files to a directory on the specified path!;
• Added support for HPFS386 file system (HPFS386);
• Added support for parallel port ZIP drive (PPZIP);
  
• Added support for using lxlite when copying files, freeing extra space! (LXLITE);
• Added option for using the small keyboard.dcp file from the Warp 4 boot disks, saving yet again quite some space! (SMALLKEYBOARDDCP);
  Note: This keyboard.dcp most likely only supports a very limited set of keyboard layouts...
  
• You can now specify additional ini file lines using the format of the makeini command (EXTRAUSERINI, EXTRASYSINI);
  
• Added configuration variable for specifying the command shell prompt (SHELLPROMPT);
• Added configuration variables for specifying the names of the boot images (BOOTIMAGENAME.1 and BOOTIMAGENAME.2);
  Note: When using AudioCDCreator, the name of the first image should be OSBOOT.IMG (now default).
