I am looking at a 386-25Mhz motherboard with an AMI bios.
The Documentation states that the area from 640K to 1Meg can ONLY be
used for shadowing the bios, video etc., and is unusable otherwise.

Has anybody ever heard of this?  Will this present a problem when 
attempting to load TSRs HI (with qemm.sys and DesqView).  Will OS/2
be a problem?

I would appreciate any information on this issue.
