When I was running 2.1, I added some memory, and the system would not 
boot.  When I called the OS/2 tech support line, their statement was "Oh, 
all of the memory in the system must be of the same type and speed, and 
from the same vendor."  Right or wrong, they are at least consistent.

P.S. I haven't had an opportunity to check my Bios yet.
