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.
