Hi,
I've bought a *new* Matrox card on ebay to replace my old Millenium PCI but
I experience some troubles.

I installed the card into a MSI Mobo (KT4V - Via KT400 - AGP1/2/4/8?) but
when I want to power up my PC, it won't boot !
When the card is uninstalled, my PC boots again...

Please, I ask you for help.
The card is labelled G4+MDHA32G bios rev. 1.09 and 906-01 REV. : A (1999).

Thank you very much !

Are the PSU powerful enough?

Thanks Ken for your reply !
Yes the PSU is powerful enought.

I've found this:

"All G400 boards are fully capable of running in both 3.3 and 1.5 V AGP
slots. However, some old revision boards may need a slight modification.
This is becuase the AGP 2X revision of the G400 boards does not have AGP
connector pin A2 (TYPEDET#) hardwired to ground (you can check this with a
multimeter). Newer AGP 4x revisions do have pin A2 wired to ground. Some AGP
4X/8X (1.5V only) use the TYPEDET# signal to detect whether a card can run
at 1.5 V. If pin A2 is not at ground potential, they may refuse to boot...
this causes a problem for our old G400s.

Solution: install a zero value resistor (or a small wire) at location R68 of
the G400 pcb (look in the large thread for a picture). This will ground pin
A2; then everything will work fine. I have tested this procedure with
success on my G400 MAX."

It appears my card needs a such modification.
But how to do this ? :-(

I think I got the solution Ken.
The A2 pin should be grounded :) 
e.g. the graphic board's slot cover.

Have you ever heard of this problem ?
Is it safe to da such a trick ?
It appears to be the only way to get this card work with newest mobo...
