Just adding to the thread a successful flash of a Gigabyte R9 270X 2GB card using Win10 boot camp'd on a MacPro3,1.

Could the combination work with a kext from older osX?
Are those available in somewhere?

Wondering if there's any chart anywhere which cards work with which osX/macOS?
Officially and with kext swapping?

Does EFI 64 version for X1900 (XT) exist?

-X1900 XT

Can Flash: X1900 XT and XTX 512MB. (Not GT, nor 256MB)

Can somebody offer this rom?

I dont think this is ever gonna work.

As far as I know, X1900 wont get past Lion 10.7.5, I think it only had 32-bit drivers (kexts).

Just upgrade your GPU, even beter to a metal GPU and get Mojave/Catalina or Big Sur on your 3,1

Hi guys!

I have a G5 and alot of old AGP cards, however now PC to flash them in.

I also have the corresponding Mac-Roms for each of the cards.

Anyone knows if it is possible to flash old cards with a EPROM programmer like the CH341A?

Using the ROM file...

I am thinking it should be possible to read out the ROM from this chip and flash it to another?

Or are they non flashable?

I dont know where this chip is located, otherwise i can check if it is programmable with the CH341A programmer.

Would be very nic...

Yes, possible. The cards use the same SPI-memory.

Not flashable.

The SMC uses a proprietary protocol, software-dump impossible.
