SUMMARY
The Toshiba T1000 laptop uses ROM DOS Toshiba MS-DOS version 2.11,
which is configured as a 256K read-only drive C. At this time, there
is no ROM DOS upgrade available from Toshiba.
You can use Microsoft MS-DOS 5.0 or later with the Toshiba T1000 laptop.
The T1000 boots from a MS-DOS 5.0 or later system floppy disk. However,
you will be unable to access the ROM DOS drive C. The HARD RAM drive D
or the RAM expanded memory (which is the same thing, just configured
differently) is accessible if you do ONE of the following:
• Run FDISK. From fixed disk drive 2, delete the two non-DOS
partitions and the Novell partition, then create a primary DOS
partition. Format drive C.
The HARD RAM drive will now be usable as drive C.
-or-
• Boot on the ROM DOS. Copy the file EMM.SYS to the MS-DOS 5.0 system
disk. Run the T1000 SETUP10.EXE program and configure the HARD RAM
drive so that there is at least 64K bytes not used. On the MS-DOS
5.0 system disk, include MS-DOS 5.0's RAMDRIVE.SYS and a CONFIG.SYS
file that contains at least the following:
CONFIG.SYS
----------
device=emm.sys
device=ramdrive.sys /a
The HARD RAM drive will now be accessible as a normal RAM drive.
