As Cyber1d and Relyt have suggested messsing with the BIOS is not a good idea.

This is ESPECIALLY true if you have a brand name computer such as Compaq, HP, Dell, IBM etc, as they DO NOT have a "native" BIOS version. It may say "Award" or "AMI", but it isn't!

The "big boys" don't want the cost of running a large help desk operation, so they have custom BIOSes that have a lot of the options removed. This is to stop people who don't know what they are doing from messing around, then ringing up the help desk to get it sorted out. To attempt to use generic or third party tools in this environment is NOT a good idea. Any updates MUST come from the supplier.

The same can be said of old ex-corporate machines that have come from large organisations. The company wants to keep its support costs down and improve security, so it specifies its own custom BIOS. I have even seen a machine where the BIOS would not let you add new hardware, or even replace a broken 3.5" floppy (there was a hidden menu).

I think that the old saying "if it ain't broke don't fix it" is a very good one as far as BIOS is concerned.
