I rebooted to find no display output from my Apple HD 2600XT. Everything seemed okay, and the flash was reported as successful. I struggled for a while getting DOS to recognize ATIFlash, so I eventually gave up and moved on to ATiWinFlash.

I gave up flashing on my X38 PC and figured I'd go for the gold on my 3,1 2008 Mac Pro. Several resolderings later I'm still in the same position. I could use the bios that you generated with the guide? thanks I already appreciate all the work you guys have put into this.ДҐ770VAPO.ROM = the original rom from the cardДҐ770vxdb.rom = the rom I made using Jeanlain's guide I think it was 04 that made flash it back to the original blind. I first tried using Rominator's M57704 and M57702 ROM but they did not work at all.

Windows XP stopped recognizing it as an ATI card after I flashed it with the new ROM, but after I pulled the old, broken, never-worked-in-Windows x1900xt out, Windows sees it just fine. Well, using this guide to roll my own ROM lets me successfully use my new card (details below) in my MacPro 1,1. Success!!! (Well, I haven't tried the HDMI or DisplayPorts, and I haven't tried to see if the startup screen show up without using a VGA cable) (I'm going to try a DVI-to-vga adaptor tonight because someone posted they had success seeing the EFI boot screens with this). All three displays are running well at native resolutions.ДЄs with everyone else, I do not see the EFI boot screens, but as soon as MacOSX boots all the displays come to life. I have tested with both DVI ports connected and a MiniDP-to-VGA adaptor. No need for the dos-based atiflash.exe -p new.rom -f to force the new.rom onto the device when the IDs don't match. I could do this because I was using the original ROM with the 'added efi bits', therefore the IDs matched (IDs in the card ROM, and the IDs in the modded ROM). I then used Win ATI Flash (the windows-based flashing tool) from within XP. I reverted back to the original ROM using the CD. I tried some of Rominator's ROMs with boot CD, with varying degrees of success, then I found the forum thread make your own radeon HD 5770/5870 Mac ROM, so I followed those instructions and built my own ROM from the card original.

Tip: Install the latest ATI drivers for the 5770 card. This didn't work initially, the ROM version field 'looked wrong' and the tool kept telling me 'saving was not available on this card/model'. I used GPUz from TechPowerUp to read and dump the original ROM. I mention this because others should know that you can't really use Vista64 for many of the tools listed on these forums, the Atiflash.exe just wouldn't run (and yes I now know it's better to build a DOS-based CD and boot from that ).ДЄfter a day of frustration, trying to build a bootable flash memory stick (don't do it unless you are building a hackintosh, it won't boot a Mac or at least I couldn't find a way to do so), building and using DOS/Linux hybrid boot CDs, I ended up building a second Boot Camp partition running WinXP. My Boot Camp partition is Windows Vista 64-bit. I'm using a MacPro 1,1 with Snow Leopard 10.6.7, lots of RAM. I haven't see this model listed elsewhere so I have attached my modified ROM.

I thought I'd post my experience and the method I followed in case it helps others.

I think it may cause an issue where the hot air recirculates by being pulled back in through the cooler fan. The only thing that still worries me is that this model inexplicably exhausts against the normal air flow. I selected the XFX Radeon HD 5770 HD-577X-ZMF3 Version A.4, it is a single slot, dual DVI + MiniDP for just over 80 UK Pounds. I knew I was going to try and flash it so I didn't want to drop too much cash on this my first adventure with MacOSX and flashing graphics cards. I decided to do as others before me and buy a PC-variant ATI 5770 card. So I was looking around for a new gfx card, all roads seemed to lead to this forum. I will try and clean it to see if it will work again or if it really is toasted. My Nvdia 8800GT recently fried itself (actually I didn't clean the fins of the heat-sink after having cavity wall insulation installed - lots of small fibres in the air!) it lasted a while then overheated. I'd like to say thanks to everyone on this forum, especially Netkas and Rominator (and a host of others who help out). Not all combinations of connector/adaptor work, but I simply use both DVI ports in a dual screen setup and this works great for me. The good news is that Fl0r!an's modified EFI part works well for this make/model. I've been working to test these ROMs for my XFX. Forum member Fl0r!an has been working to modify the EFI part for some of the ATI cards to enable boot screens.
