[comp.sys.ibm.pc.hardware] Help! EMM on an IBM X/T clone motherboard.

curtiss@hpuxa.ircc.ohio-state.edu (Brent A. Curtiss) (10/16/90)

Could some hardware guru help me out with this one?

I have an X/T clone with a 12Mhz 8088 and 1 Meg on the
board.  Unfortunately, I can only use 640K of that memory.
I haven't been able to figure out how to configure the
rest of the memory as Expanded or Extended memory so 
that it can be used by Windows 3.0 (which runs fine on 
an X/T by the way.)

Would buying a "above-board" type card help in this case?

Any help would be greatly appreciated!

I cannot comment on the use of your motherboard memory -- it is board 
specific.  However, you can buy a generic expanded memory board for an 
XT for $80 to $100 plus memory from many mail order places.  The one I had 
(when my XT was alive) allowed to configure it either as all expanded or 
all extended or as a combination of conventional (to complete to 640K if 
you didn't have it) and extended.  The board came with an expanded memory 
driver.
