Also, on a side note. I got a Matrox Parhelia, PH-A128R. This is the second Parhelia I got, and the second one that has arrived DOA. Packaging was good. Unit looks like its in good condition; very little dust build up. Fan spins up properly. I'm using a VGA -> DVI-I adapter. Am I possibly doing …

Th jumper is marked "linear" and "interleaved" modes. interleaved is the default operation mode. Linear causes the machine to crash the second it displays the system summary after the main bios screen... it doesn't even fill out the fields... just draws the ASCII frame and then hard locks. It …

The markings on the clock generator are: IMI SC643AYB 9717 F3642 I was not able to find a datasheet on it. Anybody have any info on it? Settings that are documented are: 50 55 60 66.6 75 83 I set the multiplier to 2 and was trying out the different available fsb settings that were not documented. …

Was thinking I had gotten a 233 MMX chip, but I had gotten a 166 MMX chip. I tested all the PCI video cards I have except for the ATI 9250 cards. Cards that may be faulty or maybe the board just doesn't like them: Trident 9680 - neither will post S3 - neither will post Matrox Millenium II - posts, …

I had a very similar motherboard and I always thought that it was normal that the coast module replaces any on board cache and they do not work at same time. That is why I got 512Kb coast module to begin with. It's tricky to get COAST work along with onboard cache without a clear manual. We may …

The COAST has 32k x 8 tag ram which is plenty for 512KB cache. You should pull out the onboard tag when the COAST is inserted. What's the label of JP1 on the COAST? Perhaps you need to toggle the jumper cap in order to make things work.

If you don't pull the mobo tag and don't insert the COAST stick, how much cache does the system report? It's not fake if it reports 256K.

Going to replace edo ram with sdram in this system but I'm confused about what they mean when saying (1)4mx64 and 2mx64 - at the very bottom it implies that I put 2 64mb sticks in bank 2 and 3, but the total ram is still only going to be 64mb? 64 means 64bit-wide SDRAM modules, and (1) means 1-rank …

HOLD ON JUST A MINUTE, My other computers were beginning to restart on certain applications as well.

The jumper block: 1, Fast ISA - not sure 2, VRE - core voltage: on = 3.4-3.6V, off = 3.135- 3.6V - better be off for MMX cpus 3, clear password 4, clear CMOS - so the previous guess of mine was wrong. 2nd guess: it's for BIOS flashing protection. 5, unlabeled 6, BF - this is the multiplier jumper. …

Thanks for the super quick reply. I have never done this before, so I'm a little clueless in this area. I'm pretty sure the first image is what I'm looking for, though I'm not sure, the only other jumper I found that I did not recognise was one in the second image http://www.mediafire.com/view/ …

How about the matrox g400, tnt2 and firegl 4mb? (All agp) G400 was expensive and high end so I'd say P-III. TNT2 ranges from high end Ultra to low end Vanta, so it depends on what version you have. FireGL - I assume you meant the Permedia1/2 chip version - was intended for low end 3D CADs. I'd get …
