DOCUMENT:Q94334 21-NOV-1999 [msdos] TITLE :Using MS-DOS Upgrade Fdisk Program with EXTDISK.SYS PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.0,6.2,6.21,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22 ------------------------------------------------------------------------------- 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.
