SYMPTOMS
The following error message occurs when MS-DOS 6.x Upgrade has not been successfully installed:
CAUSE
If you cannot recover from this situation by restarting your computer with the Uninstall disk in drive A, your CMOS settings may be configured to search drive C for the MS-DOS system files.
Traditionally, the computer BIOS attempts to start MS-DOS from drive A and then searches drive C if no disk is in drive A. However, some newer AMI BIOS chips allow you to start your computer from drive C without first looking to drive A. This is incompatible with the MS-DOS 5 and later upgrade uninstall technology.
WORKAROUND
To work around this problem, modify your CMOS settings to check for a boot disk in drive A before attempting to boot from drive C.
