Ok go to bootdisk.com
Download the boot disk for flashing bios.
Get a floppy disk and run the download you got from bootdisk.com
Then unzip the new sager bios on the disk and then reboot.
Leave the boot disk in and when it comes to the dos prompt
Run the autoexec.bat
It will run the bios updater program. Just make sure you make a back up of the old bios when asked. Sorry about the low quality of this I'm just out the door for work and let me know if you have any questions.
