The manufacturer recommends the BIOS be at the latest level. I have updated the BIOS on my desktop only once before (via windows) and it worked OK, but it is now about 4 levels behind. I read that if the BIOS update does not work on your computer it could render your system inoperable. There is a pin swap procedure but if the motherboard has been damaged, too bad, it has to be replaced. Therefore, it is at the user's risk to update the BIOS.
I downloaded the windows version of the latest BIOS level as before and proceded with the install, but it did not work. The support guy recommended I not use the windows method. He recommended the diskette/floppy version (da!). I have burned a CD (ISO version) and I am scared to death to proceed. Should I purchase a usb diskette? Is this the safest - better than ISO method?
