It was not in any of those publications, but it was on both AMI's and IBM's
"informational" FTP sites, that the BIOS date must be after 6/1/1991 in order
for OS/2 to "see" all of the system's memory correctly.  Of course, this only
applies if you install 16MB or more.  It had to do with the memory address bus 
configuration.  You could install more memory, OS/2 (and amazingly Windows)
could not "see" all of it.
