Title: lbios hangs on both patched and original bios
Post by: chromium on April 26, 2019, 04:23:31 am

I'm trying to flash Atom-15 to my Radeon 7850.

I have dumped the bios using both dos and windows atiflash tools and the dumped file is identical in both cases.

I patch the bios in Atom-15 no problem, but I wanted to test in lbios before flashing as suggested by the guide.

When I run lbios from dos it just sits there with a blinking cursor. It doesn't matter if I try the original or patched bios, the result is the same.

I'm guessing this is an issue with lbios the tool on my hardware seeing as the same issue occurs with the original bios and that it doesn't absolutely guarantee that the bios will brick my card, but it also doesn't guarantee that it won't.

Do I just have to flash it and hope for the best or is there something else I can do to get lbios working?

I cannot answer the question directly, but i can relate that I've flashed a 7870 and 7950 with Atom-15 no problems. I didn't even bother with lbios as i didn't want to make a DOS boot env.

If you have another working system with a GPU in it, and a spare GPU slot, you can recover any potentially bricked card that way. Just make sure you know which number is which card :)
