The whole BIOS updating procedure should be treated with extreme caution.
If you do not encounter any system instability or bugs with the current BIOS version, we suggest that you keep it.
The CMOS contains the BIOS and its settings, the NVRAM contains the ESCD, updating the BIOS will not clear the NVRAM.
You can enter the system BIOS or Setup on a Dell PC by pressing F2 at the Dell loading screen.
I have a Dell Dimension 8100, and I need to update the BIOS from A08 to A09. Follow the Directions on this site to make your key bootable. Copy the BIOS update to your Flash drive and reboot. I believe Dell's are F12 to select Boot device during the BIOS.
Only problem is that the files supplied by Dell use a floppy disk to do the update, and I don't have a floppy drive. You can make a Bootable USB Key that will work for you. Download the A09 BIOS upgrade for your system that isn't packaged.
After posting in this forum, problems with my computer...(unfortunnately nobody except one person answered my posting) I found what the problem is. I need to know how to Flash the corrupted Bios in order to install the new one.
I am confused about the instructions in ASUS Website about installing new BIOS via DOS prompt.
The security check involves decoding the digital signature of the new video BIOS with a corresponding public key stored with the system BIOS.BIOS is also used to identify and configure hardware components in a computer such as the hard drive, floppy drive, optical drive, CPU, memory, Plug and Play devices etc.This is called the ESCD (Extended System Configuration Data) and this is usually stored in additional non-volatile memory also referred to as NVRAM (Non-Volatile Random Access Memory) Over the years as technology has changed people still refer to the BIOS as both CMOS and NVRAM, however they are subtly different.If you determine to flash BIOS, you are taking a personal risk of BIOS flash failure.Please contact your supplier or our distributors/resellers for further remedy in case system crashes unfortunately because of BIOS flash failure.
