SUMMARY
=======
If were using COMPAQ MS-DOS version 4.0 or later before you upgraded to MS-DOS
6.0 or later, and you are using EXTDISK.SYS, you should use the COMPAQ version
of the Fdisk program. If you were using COMPAQ MS-DOS version 3.31 or earlier
before you upgraded to MS-DOS 6.0 or later, and you are using EXTDISK.SYS, you
should contact Compaq for an updated version of EXTDISK.SYS.
MORE INFORMATION
================
Some COMPAQ systems use a driver called EXTDISK.SYS to access secondary disk
drives. This driver is MS-DOS version-dependent. If you use the MS-DOS version
of Fdisk when EXTDISK.SYS is loaded, Fdisk displays incorrect drive letters for
the hard disks attached to the second controller.
WORKAROUND
==========
You can work around this problem by using the COMPAQ version of Fdisk. To
install the old version of Fdisk:
1. Delete FDISK.EXE from the DOS directory.
2. Copy FDISK.* from your COMPAQ MS-DOS disks to your DOS directory. For
example:
copy a:\fdisk.* c:\dos
3. Add Fdisk to the SETVER.EXE version table for your version of COMPAQ MS-DOS.
For example:
setver fdisk.exe 4.0
4. Restart your computer.
NOTE: You must use SETVER to tell EXTDISK.SYS that you are using a previous
version of MS-DOS. For more information, query on the following words in the
Microsoft Knowledge Base:
