Here is a follow-up.... After reading this posting...

I didn't have time to apply to patch, but I did change my kernel boot
line to read:
c:/1/kernel/1.3.75 root=/dev/hda1 ramdisk=0 vga=0 ro auto
This seems to work perfectly. The problem only occurs when a higher
video resolution is selected. This could be a major problem is it breaks
Linux-FT Unifix Boot Manager, LOADLIN, and others.
This list is a real help. Thanks everyone.
