It is not that I am uncomfortable in flashing bios, even though I have bricked a motherboard in the past (with supported BIOS and tools), this process was a pain. But seeing as this was a completely unsupported endeavor I really took my time. But I really had no choice any way. Used Techpoweredup's quide for flashing video BIOS and in the long run it was a wise if frustrating choice. The worst part was all the broken links plus utilities that had been taken down at the request of AMD. And of course when I went to flash the BIOS on my 5770 Xfire config I got all sorts of errors (but no bricked video cards). But in the end I used the most risky option: c:\atiflash -p -f N 5700new.bin Where N is the video card number for each card. Had to do that because there was new mismatches in two different identifier strings, sigh. And as I finally figured out this was a BIOS "downgrade". The "new" BIOS is actually a slightly older generic ATI BIOS, but so far the only downside to that is that sitting at idle the cooler fans are spinning noticeably faster (I couldn't discern them from the rest of the system before). To add insult to injury my Catalyst install didn't recognize them on reboot in to Win7. Thankfully a uninstalling, rebooting, a fresh install and another reboot everything is working. One interesting note is that even after the re-flash my custom Overdrive settings were retained. Strange, no? Now to tackle the fan issue. John What a eff’in PITA!
