Ewww, WinBIOS. :( Personal preferences aside, I think someone at AMI put in some rather overzealous boot-sector virus checking...I get the feeling that someone there forgot that there are non-Microsoft OSes in this world. :( Check the setup program--if there's an option for it, turn boot-sector virus and modification checking off. > > (and does that FCC certification sticker have an ID on > > it?

In any case, it's an AMI BIOS, and I know AMI has added a bunch of virus-checking routines to their BIOS. It appears that they check to see if the boot header on the drive is 0xEB foo 0x90, and if it doesn't match that profile, it cries wolf and won't boot. PS: AMIBIOS was good UI-wise until WinBIOS came out. And I don't like the AMI-based BIOS used on Intel motherboards, either--not configurable enough. I'm a fan of the old AMI Hi-Flex text-mode setup, and of Award BIOS. -- Lee C. -- Manassas, VA, USA (WakkyMouse on WTnet #watertower) A!
