[KLUG Members] AGP problem (maybe?)

[Scott Thurmond]

I flipped through the settings to see what was there last night.  I have 1
256Mb dimm on the board but I have some old memory laying around - I think a
64Mb dimm.  I haven't tried taking the 256 out and using the 64Mb.  Is that
worth a try?  I don't recall seeing a 256 setting for memory aperature.

I've seen this. (Don't even ask why someone had a *server* with an AMD
processor
and/or a AGP card.  Ick on both, IMHO).  In that system's BIOS it was called
"memory aperature".  The system originally had 128Mb of RAM and worked fine.
They added 64Mb for a total of 192M,  and the server blew up chunks all over
the
nice XFS tiled floor.  The memory aperature was set to "128M",  changing it
to
"192M" (I was a little suprised that setting was available).  It seems to
shove
the address space the card uses up out of the way.  The card was using 16Mb
(why
oh why on a server...) and the OS then found 176M and tooled along as
happily as
crappy PC hardware ever does.

AGP = A Game Platform.  Cheap tricks to get better video performance - IMHO.
