[comp.sys.ibm.ps2.hardware] Problem with XGA Board

"WILLIAM FRANKLIN FLUSEK" <flusekw@ucs.indiana.edu> (03/28/91)

Hi Netters,

I just got my XGA board yesterday and here is my tale of woe. 

First of all the board has a different configuration than say the 8514/A 
board (which it was intended to replace).  The 8514/A requires a slot with 
an auxilarly video extension (as do anybody elses MCA video cards) BUT the 
XGA card requires a slot (preferrably a 32 bit slot) with a BASE VIDEO 
extension.  The card WILL NOT plug into the 16 bit slot with the video 
extension in either of my machines (80-311 or 70-A21) and is not supposed 
to do so.  I did get the card to work, but to do so I had to run the 
machine with a monitor on the VGA and one on the XGA.  

I was very disappointed.  Also, it is mentioned in the documentation that 
there is a compatibility problem with some 80-111's, 80-311's, 80-121's and 
80-321's (20 Mhz Model 80's basically) and that does include mine.  The 
board causes the machine to lock up whenever the XGA is accessed.  There is 
mention of a fix from IBM, but I haven't had the chance to look into it 
yet.

I would like to run this board as the main video source (one monitor only) 
for my system.  Is there a PS/2 (short of the 90 or 95 which come with XGA) 
that has the BASE VIDEO extension on a slot?  I just paid nearly $1000 for 
the board and memory and would like it to work for me!  I will post a note 
on the IBM Support Center BBS this evening also and if I get a solution 
from them I will let you know.

If you have a 386, 386sx or 486 PS/2 and are looking at the XGA board as an 
option, procede with care.  If anyone would like more information on the 
board, I will let you know what I can.

Hi again,

I am a bit embarrassed at present.  I did finally get the XGA board working 
properly in my Model 70.  I think that I must have read at least a dozen 
times that the board is a busmaster board, but it never seemed to take 
control of the system.  Well, after it got rebooted without a monitor on 
the system board VGA, it did in fact take over and ran all of the video out 
of its port.  I works just fine.  

As far as the model 80 goes, I have gotten a note that suggests the 
solution is a system board replacement.  Since the machine is well out of 
the warranty, I imagine that I will stick with the 8514 board in it for 
now.

The only other comment that I can make at this point is that IBM needs to 
look seriously at NON-INTERLACED display systems.  There are somethings 
that I have pulled up in Windows, OS/2 and AutoCAD that can give you a 
headache in less than a minute due to the flicker.  But the high resolution 
really makes Windows look like a REAL environment and not something from a 
toy.  (This comment has been made my me and to me several times recently).

Thanks for all your help,
