Please post your motherboard brand and model.
Please advise your bios name, such as AwardBIOS, or AMI, or Phoenix, or other name.
Also, do you have a floppy drive installed?
There are some flashing aids for particular motherboard/chipset combinations that might help you, depending on what you have.
Here are some ONLY GENERAL things to think about until you reply:
* Before flashing, make a backup copy of your present bios.
* Boot into your old bios and set everything to the default values.
* Don't flash from Windows with WINFLASH
* If your computer has a floppy drive then in general, you'll take a blank floppy disk, make it bootable, and put the NEW bios file and a flashing utility onto the floppy disk.
Then you'll boot to DOS prompt, and enter a command that runs the flashing utility. The command you enter will include some switches. All this can be explained in detail after you reply.
* Then you boot up to see if it worked.
* After success, you again boot into your new bios and tweak settings to your preferences.
