[comp.os.os2] OS/2 and non-IBM hardware???

While IBM OS/2 may not run at first on a fair number of clones, comments
I have seen by people indicate that with some effort and ingenuity they
have succeeded.  The most common problem I have heard of (which can even
block installation) is related to the keyboard BIOS.  A particular AMI
BIOS version which is common in many clones does not work correctly.  People
get this ROM replaced and solve their problem.  The other more difficult
issue is hard drive support.  A significant number of people who have
SCSI drives have discovered that the presently available versions of OS/2
do not provide support for this drive.  This may improve soon since I have
heard that IBM has announced a SCSI drive option for one of their machines
and people say that this means that they will provide SCSI support for
OS/2.  I am not sure whether SCSI is sufficiently etched in stone to 
assure that IBM's SCSI will work with other vendors SCSI.
Regarding Hercules, there seems to be no support available and little
enthusiasm from Hercules to provide it.  I suspect that the majority of
people going to OS/2 already stepped up (?) to EGA or VGA, so providing
the Hercules support was not important.

Regarding hardware requirments, a good reference with regard to OS/2 1.1
is an article called "The truth about Presentation Manager" in PC
Magazine, Vol. 8 No 7.  It is written by Charles Petzold and talks both
about the minimum requirments and the desired configuration.  He says
that 1Meg RAM (yes, that is what he says) can work, if no DOS compatability
box is used.  When I first got 1.1, I ran it with 2 Meg and it worked with
no crashes, albeit slowly with lots of swapping.  I now have 4 Meg and find
it much more responsive.  But if you are apt to be running one of the new
monster apps (i.e. Lotus 123/G) people say 6 Meg begins to make sense.

Finally, on the matter of upgrades to 2.0, I have seen no mention of any
prices on this yet.  Since 2.0 seems to offer some real benefits over 1.x,
for people with 386 machines of course, I would not be surprized if there
is some sort of upgrade cost and the size and pain of it is mostly in the
eyes of the beholder.
