Before you try flashing the bios again, try running sisoft sandra or cpuid (both are free downloads) and see what speed your barton is running. If the speed is 1.83, then you don't need a bios update. Or you can simply adjust your cpu fsb to 166 or higher if you want to try overclocking. For bios flashing, I use a windows 98 bootdisk. Find a floppy disk and format it. Then load the bios and flashing program off shuttle's website. During bootup, you'll see a bunch of stuff saying that your hardrive isn't partitioned correctly. Ignore it. At the "a" prompt, replace the bootdisk with your floppy containing the bios programs. Type "dir" and copy down the bios files exactly as they appear on screen. Then type the bios flash program and let it load. Follow the directions exactly, and don't reboot during flashing. It will tell you if the flash was successful. Then reboot, press the "del" or f1 key to enter the bios, load the defaults, save and exit. Again, if your system is running at the correct speed, I wouldn't flash the bios. All the bios update may do is recognize your barton correctly. It may not improve performance at all.
