This heavily smells like a hardware problem.  Try changing your memory
timing, or disabling write-back cache.  There's a lot of broken
hardware out there, alas.  (Dos doesn't use the hardware to the amount
a Unix does.)

This looks like the message that I got when I tried to install 2.1R on a 
machine with 4 MB of memory.  Adding more memory cleared the problem 
right up.
