I've been trying, unsuccessfully, to update BIOS so that I can upgrade my processor from a 1.5 MHz to a 2.4 MHz pentium 4 (currently I have a Pentium 4, 1.5 MHZ, 400 MHz bus, 512 MB ram, windows XP). To update BIOS (the Motherboard is an Intel D845HV with 845 chipset), I downloaded Intel's "express bios update utility" (http://downloadfinder.intel.com/scr...XP+Home+Edition&lang=eng&strOSs=45&submit=Go!) but when my computer boots it always say the upgrade was unsuccessful and it refers me to the readme file. I have not been able to figure out what I'm doing wrong - but I've never tried this before! One thing it says is to shutdown all windows programs. I have both Norton internet security and Roxio Go Back installed. Could these programs be part of the problem? Can I simply disable these programs, or do I need to completely uninstall them (a real pain!)? Is there another possible cause? Is there another way to do this? Thanks!
