AGP Card Issues

[JEWilson]

Have a Leadtek FX5700 LE 256MB AGP 8x.

This card will light up the video LED on my LCD screen but I get no
video - the screen stays dark.

I suspected bad caps but these check out ok

I used a PCI card to establish if I could see the card with nvflash.

nvflash correctly IDs the card as above but states it
cannot set the prom pins on the EEPROM.

I thus suspected the card had a bad flash.
I cannot even backup the BIOS on the card - same issue

When I try to flash the card with a more recent bios - same issue
This is using both nvflash v4.41 and v5.88

I tried using LeadTek wfflash v4.8 but this states it cannot find
the card at all.

Note, the AGP card is not shown in the device listing at POST but
the PCI card is

I can only concur this AGP has, as suspected a corrupt or non-existent
BIOS. Here, the BIOS may have been erased.

Having used both nvflash and wfflash these are both not working with
my attempts to reflash.

Are there any other approaches I can try here?

Re: AGP Card Issues

get an EEPROM from a dead card?
or try to flash the FX5700 one on a different card with the PCI card for video..

sounds like either the chip itself is bad or someone flashed the wrong BIOS file to it..

Hi

Thx for responding

I have a number of cards purchased from the same seller with the
same problem. To be fair, being I got these so cheap, I cannot
return them.

What I will try first is to strap the CE pin on the EEPROM to gnd.,
as the message from nvflash v5.88 indicates whilst, apparently, it
recognises the EEPROM (an SST 25VF512, a 64kB part), it cannot
enable the IC.

Having done, this I will attempt to flash the bios to the card with
the -j switch.

If that does not work, then I may have to remove and/or replace
the EEPROM IC for the adapter and flash it accordingly.

Again, thx
