Hello.
I recently acquired this 64MB Radeon 9100 (equivalent to a Radeon 8500LE), and just like I did with another 9100, I decided to flash it.
The previous one worked with the original ROM by adjusting the speeds to 250/250.
This graphics card came with a 64KB EEPROM, a PM39LV512, and since the original ROM is 128KB, I flashed it onto an AM29F010. I verified that the extra pin was traced on the PCB, and it was; it's routed.
After soldering the EEPROM and installing it in a G4 GE, which now has a flashed 8500, there's no image. Using an ATI Rage Pro PCI card, I can access the system profile and view the information, but it doesn't match what the 8500 displays.
Working Radeon 8500:
Radeon 9100 flashed:
Does anyone have the ability to review the two dumps I've attached and see if there are any incompatibilities? I also have the ROM that @joevt modified many years ago, but I don't know if it would be more compatible or if they're similar. I'm attaching it as well.
Thanks.
