Well, I spoke too soon! after installing SP1, I rebooted and the thing wouldn't boot; it halts at the first boot screen with the following: "Bios Rom Checksum Error; Keyboard error or no keyboard; detect floppy Drive A, Drive A error; system halted"; it is doing this about 9 of 10 boots; funny thing is on that 10th boot, it will only recognize my 2.4 P4 as a 1.8; I have cleared the cmos about a million times but nothing seems to work; so I guess I'm stuck with a 1.8 for the weekend!
