Title: Error patching BIOS with ATOM-15
Post by: big10p on March 23, 2017, 12:27:57 pm

Hi

I'm getting the "hook not possible" error that's discussed in this thread:
http://forum.arcadecontrols.com/index.php?topic=148991.0 (http://forum.arcadecontrols.com/index.php?topic=148991.0)

My card is an HD5450 and I'm using ATOM-15 v1.2. I did notice that the BIOS image I dumped using atiflash -s 0 bios.rom looks unusually big at 262,144 bytes.

Anyone got any ideas?

Cheers

Please attach your bios so I can check it.

Has anyone with an HD5450 managed to patch the BIOS successfully, or is it an unsupported card?

The HD5450 is supported and has been patched by many users. However your card has a newer EFI BIOS that can't be patched with current ATOM-15. I'm testing a new version that's able to reallocate the EFI GOP block in order to patch the BIOS properly. If my tests are successful I'll release it this week.

Sorry for the late reply, Calamity. Been really busy and haven't had a chance to try this out, yet. I'll report back as soon as I'm able to try it out.

Thank you!  :applaud:

Managed to try this out today, and it worked a treat. Thanks again, Calamity!
