I am on a 'pure' IBM pc and have the same problem with read errors 
ocurring while typing with hard disk activity.  I dont think it is a 
compatability problem.  Probably a bug in interrupt handling, although 
I have not looked at that code yet.

I also had problems with multiple partitions so I went ahead and started over
with one partition and it worked fine.
