Gigabyte P55A-UD3 Rev 1 AHCI BIOS Update from 1.20E

[Groupers]

The 1.20E AHCI BIOS in this and probably half of Gigabyte's boards has a bug where it will freeze while detecting drives and requires manual editing of the MBR or a complete reinstall of the OS. I've had it with this bug and I hope someone here can help me.

Please update the AHCI BIOS from version 1.20E to ANY newer version. There appears to be some more information on these forums for the AHCI BIOS with some downloads here: http://www.bios-mods.com/forum/Thread-GA...DS3?page=2

Thanks but AHCI doesn't even show up at POST with this one. I was impatient and started reading and [censored] around a little and managed to find another version of pchahci.bin in some GB BIOSes. I downloaded the newest BIOS for every one of their P55 boards and extracted pchahci.bin from every BIOS and diff'd them all.

The other version I found works and shows up during POST but I have no idea how to tell what the version is. For all I know it's even older than the one I already had, as they both display 1.20E. Could you take a look at these two files and let me know? http://old.bitsurge.net/bios/GB-iSrc_1.20E_ROMs.zip "_1" is the original from my BIOS and "_2" is the different version that I found.

I didn't think the 0027 would work for you but it was worth a shot.
As for the other two you posted, there is no way to tell which is newer by looking at them but they are Slightly different.
I used WinHex to compare them.

Personally I would just use whichever one works for you.
