I have just built the following system:
ASUS P4P800-E deluxe
P4 Prescott 3.2Ghz HT
1x 40Gb HD 1st IDE Master
1x DVDRW combo 2nd IDE Master
Everything seems to be fine when running with an ATI radeon 9100 128MB 4x AGP installed.
However, the intention is to put my 4 week old, triple head Matrox Parhelia 128MB 8x AGP card, in this system.
At the moment, this does not work at all.
What happens is, I turn on my system and get a full screen of one colour (either pale green or pale red) for about 10 seconds, then the monitor switches off and then on again after a further 5 to 10 seconds. Windows continues to load, I can see the IDE LED working but I just have a black screen.
On the Matrox Forum (which infuriatingly is not available even for reference over the weekend) I researched this problem. According to a number of threads, there is a known issue with Matrox P series cards on the ASUS 'P4****' series motherboards. They say that problems can arrise because of the ASUS logo screen which appears before the usual BIOS loading information and requires a 101h graphics mode configuration. They provide a number of BIOS fixes for the Matrox Card.
I should say that I currently have no problems running my Matrox Parhelia in my Optronix OP-A26P5-ML8 motherboard with a Celeron 2.4Ghz processor.
I put the Matrox card in my Optronix board and ran the following fixes:
1. Upgraded Matrox BIOS to latest.
2. Ran VBE graphics Matrox BIOS fix
3. Ran ASUS startup logo Matrox BIOS fix
4. Ran startup logo colour fix for Matrox BIOS.
I then checked my ASUS board for the latest BIOS, this was v1004.001 which was the version installed on my system but I decided it would do no harm to flash it anyway.
Following this I again tried the Matrox card in the ASUS board. No change!
The technicians on the Matrox Forum seem to be saying (from my reading of other's posts) that there should be no problems running the Parhelia card in the ASUS board, it is designed for 0.8v or 1.5v AGP slots, (although this information is somewhat ellusive).
Since the Matrox Card works fine in another system and the ASUS board has no issues when running with a different graphics card, I have no way at all of knowing which product is at fault!
Should I get the Matrox Card RMA'd, could I have misconfigured something when building the ASUS system?
I'm really at a loss.
