I can't use any BIOS features, because none of my (USB) keyboards or mice work in Visual BIOS, which is the default mode. The keyboards and mice work in Windows, so there is nothing wrong with them. I have updated to the latest BIOS version (0023) and also installed the drivers available from Intel Download Center.
Symtoms:
In Visual BIOS, all keys on the keyboard are dead, except for ESC. Once I press ESC, I can tab myself around the dialog window and exit, but that's it. The mouse pointer can only be moved up and down, not right to left.
