Be very, very sure you understand it all. With any Award BIOS we have ever seen, there are very complete instuctions also available at the site.
We have seen so many ruined motherboards in our shop that were destroyed by someone not fully understanding how a flash install of the BIOS actually works, and how long it takes.
The problem is that there are about 15 ways to update a BIOS, and one is not the same as another. Some can boot from a USB drive. Some will only boot from a floppy drive disk, while others are first installed to a CD as an ISO.
Any BIOS installed incorrectly can permanently kill the motherboard.
It is better not to do it at all, than to do it incorrectly. Double check the site where the you found the BIOS for download.
