AES-NI support in TrueCrypt (Sandy Bridge problem)

Could someone reupload the modified bios for the G73SW

Link should still work http://dl.dropbox.com/u/8126588/G73SW205_AES.zip

I cant flash that BIOS , says it failed.

Someone else tested it recently, and it worked then. There are certain possibilities:

1. The file is corrupt - download it again.
2. The method you use to flash the BIOS doesn't work, try another.
3. The G73SW you have is a different variant that is not compatible with the BIOS. Download the regular one from the Asus US site and try that, as it should be the same, except without the bits flipped for AES. If it doesn't work either, that's the issue.

It says "read file failed" when i try to flash it

Teazle had the same problem, and posted a solution:

related note: WinFlash does not like the filename G73SwAS_AES.205, it seems to fail trying to find it. It would appear WinFlash only likes files in the 8.3 format, so I renamed it to G73SwAES.205 to get it to work.

Actually I specified in my instructions that came with the file NOT to use Winflash. This also goes under bullet #2 I posted above about trying another method.

"The BIOS file version does not match the BIOS rom version" on winflash.

If your existing bios version is the same as you want to flash then you must add .rom extension to file and use easyflash.

I flashed my modded 203 version bios for G74SX, over official 203 version. Of course you have to put the modded .rom file on a FAT32 memory stick.

hello,

I have a G73SW with a i7 2630QM
I downloaded the file G73SW205_AES, flashed with easy flash, no complains, the laptop runs fine, but i still can't get aes. What could have i miss ?

is the link Skywise posted contains the same bios than this one ?

Since there seems to be a great demand for an AES cabable G73SW BIOS and modding it is still a bit involved, I decided to patch the image for this model as well.

You can get it here: G73SwAS_AES.205

The mod required both a microcode update and an MSR patch. This must be the reason the MSR-patched version from Dufus didn't work for everyone. Microcode version for CPUID 0x0002067a (i7-2630QM, maybe others) in this version is at 1B so it should work for all of you.

Thanks

Some 2630QM CPUs don't support AES-NI out of the box and need a microcode update in the BIOS. The file I uploaded doesn't have that, and unfortunately I don't know how to add the necessary code. There's some more information further back in the thread on how to do it however.
