I tried it with MagicISO and had problems with the resultant disk. I used WinISO (we have it registered at work) and created a working disk (although it was over 6gb in size, apparently it didn't remove the old file first and left the space allocated, lol). I'm going to roll up an ISO with the new Windows ADK tonight and upload it.
The easiest way would be to use the Windows 7 USB/DVD Download tool (
here ), use it to create a working Windows 8 install key, then replace those 2 files in the sources folder on it.
*EDIT* I created a bootable DVD image with oscdimg.exe, and it booted fine, and the files installed on the VM were the newer, working amdsbs.sys. I'll be sticking it up on my 4shared folder tonight, and I'll see about some sort of alternate method after someone else can verify that it worked for them as well..
I've got to say, for a system that will either make or break Microsoft, to let this bug make it into the shipping release is pretty bad, since it's not just Raid that has the issue, it's also AHCI in general that's affected..
The only issue I can see thus far, the permissions on those files are still set to full control for administrator, unlike other files in those directories which are set to read/execute. If that's a huge problem I'll see what I can do, or you can change the permissions yourself. I did try to reset them to the TrustedInstaller owner, but the system wouldn't let me do that after replacing them.
