Funny thing is that when the machine is powered off and physical PSU switch is used, upon boot the SLIC table is present again ...
Thanks for the files 911medic. I have the same hardware as marcusanton and was using the BIOS he posted until recently when I became deactivated during a driver update. Unfortunately, the OEM7 BIOS that you posted fails to boot for me. The ISA BIOS you posted boots fine but Vista fails to activate. Mind you that the old mod that was working before does not activate Vista even after flashing again. So it might not be a problem with your BIOS. I am assuming that your BIOS are for ASUS OEM certs.
