Voodoo5 5500 PCI DVI And System Power Up Problem

[DragonBoy]

Hi guys,
I've just purchaced a Voodoo5 5500 PCI DVI mac version of course hoping to flash it with the pc voodoo5 bios. My problem is that as soon as I plug in the card the PC refuses to even power up!!! (when I press the power button the power LED comes up for a split second and then it shuts of -in other words, it just blinks-, only the power led, the system remains silent and stays off -it's like not having any power cables on it and trying to power it up) If I don't plug the power cable on the card, it powers up but of course nothing is coming up on the screen, even from the agp card. Any ideas if that is a problem that can be fixed? My mobo is an ASUS P4S533-E but I think it has something to do with the power box supply... a sort circuit or something... as soon as I remove the card, the system works perfectly fine!

thanks

Could be a simple thing as the Initial First Display in the BIOS.
Sounds like it's set to look for an AGP card and therefore won't boot.

Should set to PCI first then AGP.

If that doesn't work you might want to check the card on another machine to make sure the bios flashed worked. If it didn't grab my file here.

Hello,
thanks for your answer. I've tried what you said... changing the settings on the bios but its the same thing again... I even tryed it on another pc, a compaq p3... again the same. the pc just refuses to power up for even a second...

So it's happening on two separate machines! This would indicate it's the card.
Either the card is no good or it's not flashed properly.

OK, first thing is first I guess, do a thorough visual inspection of both sides of the card for missing surface mount components.

If that's cool I recommend you flash your VoodooMAC again with my file! (see link in my Signature below)

Stick in an AGP card and set the BIOS to boot from AGP of course.
Put the voodooMAC in any PCI slot with the extra molex power connector plugged in. (Tell me, does your system boot with this setup?)

If you can boot with both cards installed getting video from your AGP card, you can run a DOS utility called pciscan.exe from http://www.nu2.nu/utils/ to see if your card is being detected.
This is last ditch effort though cause the flash utility would tell you anyway if it didn't find your VoodooMAC.

Grab my MSN if you need to, it's on my profile.

the card is dead.  something on the card is shorting out one of the power supplies (12Vdc or 5Vdc).  could be just a fan?  you could try unplugging the fans from the board and trying it....

trigger... the problem is that the pc is not powering up at all! Is as if I don't have the power cables pluged. the only way to make it power up is when I don't plug the extra power plug on the card (but of course nothing comes up from the agp card). I also did a thorough visual inspection of both sides of the card... no components apear to be missing or blown up...  bloodworm I've also tried to remove the power on the fans but it's the same... Maybe the card is faulty after all...

Sorry I'm with you now!

If I don't plug the power cable on the card, it powers up but of course nothing is coming up on the screen, even from the agp card.

This is really strange! It's like it's defaulting to the PCI video Card even when you tell it to use the AGP video in the ASUS P4S533-E BIOS. Normally it would ignore anything on the PCI bus and show you an AGP video bios screen and boot.

The VoodooMAC is doing something on the PCI bus to confuse the mobo. Have you assigned an IRQ to the video or anything?

I'd try a regular PCI video card in place of the VoodooMAC just to be on the sure side of things. Make sure the mobo bios is not to blame.

Basically get the mobo doing what it should do "without the voodooMAC". Then try it "with the VoodooMAC".

I'd also start clean and clear the CMOS and cut everything back in the BIOS.

Failing that..... it's something dodgey with the card for sure.

I've cleared the bios and tryed again but I get the same results...
I've also tried a matrox mystique and it works fine...
