|Just the boot options and the boot order serveral times. I also changed an option concerning Boot integrety services. It appears to be a PXE option for booting over a network. That's pretty much it.|
Update: There was one BIOS change I overlooked. I had also disabled the USB Emulation as the setup said it was for OS's that did not have USB support. It is to allow USB keybords and mice to work in those OS's. I turn it off as I am not using one of those OS's. What the setup doesn't tell you is that it is also needed to boot up on the CD/DVD-ROM and floppy drives since they are USB based. After turning on the USB Emulation in setup, I was able to boot up the Smart Boot Manager that I had on a floppy disk, as the floppy drive was in the D/Bay at the time. I forgot about that setting as I had done that about three months ago which was when I had flashed the BIOS to A08. I had flashed back to A07 yesterday.
Update 2: I was testing the other setup settings and it appears that the only other setting that can affect the boot process is on page 3 for the boot settings. The boot speed should be set to 1.8GHz and not the slower Compatibility option. The compatibility option prevents Linux boot CD's from booting. They will just hang. I suppose this option is for some rather old software. Non of the other options seem to affect the boot process not counting the boot order screen on page 2.
