While it is preferable to use an Original Bios Directly from the manufacturer, AMI and Award Bios files can be backed up and modified without any problem. Just use the AFUWIN (for AMI) or AWDFLASH (for Award) to make a back up and mod that. Sometimes this is the only option availabe due to manufacturers not providing Bios files for download. Phoenix Bios files Can NOT be backed up and modified though.
