Blaster on IBM PS Value Point series of machines.

Description

User will not be able to see any display on the monitor after connecting 
the Video Blaster to the VESA feature connector on the IBM PS Value Point.  
Disconnecting the feature connector cable from the Video Blaster and the 
feature connector on the motherboard will allow user to get display output 
on the monitor.

This problem occurs because the layout of the feature connector on the IBM 
PS Value Point does not follow the specification define by VESA.  
The location of Y-pins and Z-pins are reversed on the IBM PS Value Point.  

For example:

Normal VESA connector

Y-pins are located at the bottom row of the feature connector.
Z-pins are located at the top row of the feature connector.

IBM PS Value Point connector

Y-pins are located at the top row of the feature connector.
Z-pins are located at the bottom row of the feature connector.

Revision 2 of the IBM PS Value Point motherboard have corrected this layout 
problem and should not have problem with Video Blaster.



Solution/Action

For user who have revision 1 (or earlier) of IBM PS Value Point, the only 
solution is to disable the onboard VGA and use an external VGA card that has 
feature connector conform to the VESA specification.
