Cannot flash Powercolor HD 5770 (adapter not found)

[arztt]

Hello Guys,

I'm using a Powercolor Radeon HD 5770 (this one: http://img.hexus.net/v2/news/PowerColor/PLAYHD5770.jpg) and want to edit the bios (clocks and fan control).

But when i want to use atiflash, it tells me everytime "adapter not found".

Even when i use atiflash.exe -i no adapter can be found.

Do i have to chose other settings in mainboard bios (mainboard is Gigabye GA EP35-DS3R) or why my card cannot be found?

I'm booting from USB stick with DOS on it.

maybe your atiflash version is too old, check the one from our downloads section

^ that and make sure the adapter ID slot is correct.

Here's a really good guide to USB flashing (and flashing in general): http://www.techpowerup.com/forums/showthread.php?t=57750

I downloaded a previous ATI Flash version from Sapphire site (3.75) and now it's working fine!
With the new 3.79 ... no chance!

Strange is, that the 3.75 has a 3 times bigger filesize than the 3.79
