I was so happy to plug in and use my lovely new apple aluminum wired apple keyboard. All worked perfectly. All until i restarted. My bios hung at 'initializing usb controllers.......' It will never boot. I had to unplug my Aluminum KB and plug back in my macally kb. The only way i could get it to work was if i set the bios usb controller to 12mbps it would work. I was very upset. So i went to the Asus web site to find out it was not a mac problem, but an Asus problem as other usb devices also prevent booting, and the mac keyboard works fine on many other PC's used as Hackintoshes.
So I kept looking at the Asus forum and the very last post said that the latest bios just released this month (bios 1202) fixes these usb problems at boot.
I downloaded it and Viola!
Just thought i would share this as I couldn't find any posts about it here.
