Hello.
I have a rather odd issue with one of my AGP cards, this is not something I have encountered before.
I tried to pair this card with my P4P800 P4 3,0 ghz system. When i turn on the machine, i get video output. However, the output seems to be stuck and frozen at the very first frame the computer outputs to the graphics card. In this case, its the BIOS POST screen. Mind you, the computer does not freeze. In fact, it continues booting all the way to the operating system. But the image never changes, even if i try switching between digital and analog cables.
When a card is defective, it usually does not output any image, prevents the computer from posting, signal gets cut off or the image is garbled with artifacts. Which is why this issue I encounter strikes me as really odd. I am "lucky" enough to be drowning in pentium 4 systems so i tried the card across multiple systems but I encounter the same exact issue.
I have also tried to "reflash" the VBIOS with ATIflash 3.10. Card seems to be detected just fine, though curiously ATIflash lists the Rialto chip as a separate graphics adapter. Trying to boot Linux liveCD also does not seem to work, for whatever reason i get a lot of CPU halts and other weird timeouts.
I am quite close to writing this card off but maybe someone here has encountered something similar or even better a solution. Every comment is appreciated.
