This copies your existing BIOS into a file named AMIBOOT.ROM (this name is important because if the new BIOS causes your PC to stop booting complete, AMI supports an emergency repair maneuver whereby you insert a floppy disk into your system, turn the power on, then hold down the CTRL and HOME keys until the PC beeps once to tell you it's loaded that BIOS file). You make a backup by typing this command at the C:\> prompt on your PC: AFU414sD AMIBOOT.ROM /O (the final character is a capitol O, not the number zero). Get in the habit! To make the backup, we'll use the flash utility included on the UFD. It's an absolutely essential CYA maneuver any time you mess with your PC's BIOS. This step lets you create a backup before making any changes. Why? Because if anything goes wrong with the new BIOS you're going to install, you must have some way to return to the old version. I called mine DOS-boot.īefore you can flash the existing BIOS, which really means wiping out the old one and replacing it with a new one, you must back that existing BIOS up. Grab these files and put them in their own directory. Extreme Overclocking also makes the Windows 98 system files available in a downloadas well. Of course, that means you also need a minimal set of DOS boot files (, io.sys, and ms.sys at a minimum). exe file is self installing, and adds the program to your Program Files directory by default. Extreme Overclocking has a readily available download link. It not only formats UFDs to FAT or FAT32, it can also copy DOS boot files from any target directory you supply to this tool. For this task, your best bet is a tool called the HP USB Disk Storage Format Tool, V2.1.8. This requires a special formatting tool, and DOS source files to make the drive bootable. You'll also need a USB Flash Drive (UFD) formatting tool that can create a bootable DOS image on that drive. Thus, for the MSI PR200 notebook I just updated, I searched on "download MSI PR200 BIOS." This took me right to the MSI product page for the PR200 where the latest BIOS versions for Vista and XP were both available. A good way to find BIOS versions and info is to use Google to search using strings like "download BIOS" for complete systems, or "download for motherboards. The best place to get a BIOS update is from your PC manufacturer's Web site, on the downloads page for your notebook or desktop PC, if you purchased a complete system, or for your motherboard if you built your own system (or purchased a "white box" PC from somebody else who builds them from stock parts).
