2.9 Incompatible Primary DOS Partition

If Setup referred you to this section, and no other section in part 2 of this README.TXT file is relevant to your system, you have a partition that is incompatible with MS- DOS 5.0. You must delete the partition from your hard disk. See the section "Your primary DOS partition is too small or incompatible" in Chapter 4 of the Microsoft MS-DOS Getting Started guide. Make sure you back up the files on your hard drive before deleting your partition.

Make sure you back up the files on your hard drive before deleting your partition.

2.11 286 Accelerator Card

If your system includes a 286 accelerator card, Setup may not be able to determine the amount of extended memory you have and may incorrectly install MS-DOS 5.0. If this occurs, disable the card before running Setup. If you can't disable the card, install MS-DOS 5.0 manually. For information, see the section "How do I set up MS-DOS 5.0 Upgrade manually?" in Chapter 5 of the Microsoft MS-DOS Getting Started guide.

2.16 Toshiba with a Hard RAM Disk

These instructions apply to Toshiba models T1200, T1600, T1200XE and T1000LE.

To use the hard RAM disk, do the following before installing MS-DOS 5.0:

• Back up your hard RAM disk.
• Using the Toshiba Setup program, delete the hard RAM disk by allocating zero kilobytes to it. All data on the hard RAM disk will be lost.
• Restart your system.
• Install MS-DOS 5.0.
• Use the Toshiba Setup program to reinstall the hard RAM disk.
• Run FDISK, change to drive 2, and create a primary DOS partition. Quit FDISK.
• Use the FORMAT command to format drive D.

2.17 Unix And Xenix Partitions

If your system includes Unix or Xenix partitions in addition to standard DOS partitions, and you receive a message saying a partition is incompatible with MS-DOS 5.0, install MS-DOS 5.0 by typing the following:

2.18 Apricot XEN-S Computer

To install MS-DOS 5.0 on an Apricot XEN-S computer:

• Remove the DEVICE=AEMM386.SYS command from your CONFIG.SYS file.
• Restart your system.
• Run Setup.
• Put the DEVICE=AEMM386.SYS command back in your CONFIG.SYS file and restart your system.

2.19 4DOS

Setup replaces the SHELL command in your CONFIG.SYS file with one that invokes COMMAND.COM. To recover your 4DOS SHELL command, retrieve it from the original CONFIG.SYS file, which is saved as CONFIG.DAT on your Uninstall disk.

If external DOS utilities display messages that refer to error numbers, contact JP Software for an upgrade.

2.20 LapLink

If you use Traveling Software LapLink, disable the LapLink device driver before you install MS-DOS version 5.0. The driver conflicts with the Setup program. Once you install MS-DOS version 5.0, reenable the LapLink driver.

2.21 Stacker

If you have Stacker version 2.0 or later, follow the instructions in your Stacker manual to update to MS-DOS 5.0. If youhave Stacker version 1.1 or earlier, obtain an automatic update utility from Stac Electronics.

2.22 Dell DOS 3.30

Some Dell DOS 3.30 installations were done with a utility called AFORMAT, which creates and formats multiple 32 MB partitions. These extended partitions become invisible with MS-DOS 5.0 unless you run a utility called FIXPART before or after upgrading to MS-DOS 5.0. Contact Dell to obtain the FIXPART utility.

2.23 Tandy with ROM DOS

Contact your hardware manufacturer for information about upgrading a Tandy computer with ROM DOS to MS-DOS 5.0. This applies to the following models: 1000HX, 1000SL, 1000SL2, 1000TL, 1000TL2, 1000TL3, 2500XL, 2500XL2.

2.25 SpeedStor BootAll option

If Setup directed you to this section, you have a hard disk that Setup cannot make compatible with MS-DOS 5.0. You need to install MS-DOS 5.0 manually. For instructions, see the section "How do I set up MS-DOS 5 Upgrade manually?" in Chapter 5 of Getting Started.
