[comp.sys.ibm.pc] Upgrading your XT motherboard to an AT

yon@apollo.COM (David Yon) (05/03/89)

Hey there netters...

	How many people out there have gone through the
exercise of upgrading their XT motherboard with a '286
board?  When I started this, it seemed as simple as
buying a '286 board, an XT-size 200W supply, and just
swapping  them...
  
       HA!  I started this whole charade in January,
have gone through two vendors, umpteen trips through
UPS, countless AT&T calls, and I STILL don't have a 
working unit.  Thank goodness I did not let go of my
XT board right away.  I am not a neophyte of PC hardware 
or software either.  While I'm not an EE by trade,
I'm no stranger to digital design.  Has anyone else
out there had an impossible time, or has this process
been smooth for most people?

	What I'm finally doing is having the vendor
put together a "bare-bones" unit with case, pwr supply,
floppy card/drive, and motherboard.  I will just plug
in the rest (keybd, video, other cards).  They will
test the peices together as a system before sending
it back to me.  If I'd known my luck would be this
bad (to the point of seemingly defying laws of physics), 
I would have done this long ago...

	Too bad really, this motherboard accepts up
to 4M of RAM, and the RAM above 640K (on the motherboard)
can be used either as Extended or Expanded memory without 
any other cards.  Seemed like a good deal at the time...
