EDIT2: updated for the 68706850 Preamble: this is for Mac Pros only.

Too many people here flash their PC cards with BIOS that were originally designed for other models.

Its better to make your own ROM, that is, your cards original BIOS Apples EFI (ideally, EBC for compatibility with old Mac Pros).

Notice: the 68706850 ROMs are designed for 64-bit EFI Mac Pros (e.g.

Before you start, Its always safer to enable file and screen sharing on you Mac Pro (system prefssharing).

Create a DOS volume with disk utility (it can be added to an existing partition), put the latest version of ATIflash (techpowerup.com) in the volume.

Burn a FreeDOS boot CD.

Download the iso (fdbasecd.iso ( )) and burn the image with disk utility.

Save the BIOS. Shut down and insert your PC card, remove all other radeon cards (for safety).

No need to install DOS (enter 1 at the first prompt, then 2 at the 2nd prompt).

Just navigate to your ATIFlash folder (no time to explain DOS commands here).

To save your BIOS on the DOS volume, type Code: atiflash -s 0 myrom.rom 20000 The dir command should indicate that this rom is 128KB (131 072 B).

Boot on OS X (need a working card or another Mac).

Place a copy of your saved rom and the files attached in this post at the root of your home directory.

Keep the original myrom saved somewhere.

First stage is to add the EFI section to the BIOS.

If you have a 68706850, jump to step 4.

Then check if the ROM could hold the EFI.

If only one is found, you need to.

Move the mcuc section (last part of the BIOS) to make room for the EFI.

At this stage you can trash the modified myrom.rom that only has one MCuC.

Select a large part of it.

Cut. Look for mcuc (text search field) and locate the 2nd instance, near the end of ROM.

You can switch between decimal and hexadecimal by double clicking on the dec or hex text on the bottom left.

Upward mcuc is a long string of F where the EFI should be inserted.

If the offset hasnt changed, or if you have lost the 2nd instance of mcuc, close the ROM without saving and do these steps again.

Save a copy of myrom.rom (with this name) in your home directory.

If 2 instances are found.

Correct the new offset of mcuc in myrom.

Say it has changed from 1A000 to 1A200 (if you have pasted a 512-Byte string of Fs).

To find where to indicate this offset, locate the first instance of mcuc.

Bytes upward (16 chars) you should see the original offset 00 A0 01.

Go to overwrite mode and replace this with the new offset.

Save myrom.rom in your home directory.

Fix last oprom indicator (specifies that the BIOS is no longer the only element in the ROM) and checksum.

To do it, paste the following in the terminal and hit return Code: python fixrom.py myrom.rom myrom.rom 5.

Flash your card with the new myrom.rom Credits go to pipomolo42 for the script and terminal commands, netkas for tweaking Apples EFI, and mostly Rominator for the tests.
