Setup Is Unable to Read Uninstall Disk on a COMPAQ (93679)

SYMPTOMS
If you are using SMARTDrive to cache a floppy disk on a COMPAQ machine,
MS-DOS 6 and later Upgrade may be unable to read the Uninstall disk during
installation. Setup also may also repeatedly ask you to insert MS-DOS
Upgrade Setup Disk 1 after you select the Windows-based and/or MS-DOS-based
optional utilities.
CAUSE
These problems are caused by a problem in the COMPAQ BIOS. They occur
when SMARTDrive is loaded in upper memory because all floppy disk data
transfers go through the upper memory blocks (UMBs).
WORKAROUND
To work around this problem, edit your AUTOEXEC.BAT file as follows so
that it loads SMARTDrive in conventional memory:
smartdrv /l
If loading SMARTDrive low does not correct the situation, either configure
SMARTDrive for read-caching only (no write-cache) on the floppy disk
drives, or restart your computer without loading SMARTDrive before you run
MS-DOS Upgrade Setup.
