5.1.2 Updating the BIOS using the Phoenix
Phlash16 Utility
The Basic Input/Output System (BIOS) can be updated using the Phoenix
Phlash16 Utility. Follow these instructions to update the BIOS using this
utility.
1. Download the latest BIOS le from the ASUS web site. Save the le to a
oppy disk.
Make sure you copy the correct BIOS le for the specic model of your
motherboard. Save only the updated BIOS le in the oppy disk to avoid
loading the wrong BIOS le.
2. Copy the Phoenix Phlash16 (phlash16.exe) utility from the Software
folder of the support CD to the oppy disk with the latest BIOS le.
3. Boot the system in DOS mode using the bootable floppy disk you
created earlier.
4. After posting and reading the boot data from floppy, press <F5> to
bypass some unnecessary les.
5. When the A:> appears, replace the bootable oppy disk with the oppy
disk containing the new BIOS le and the Phoenix Phlash16 Utility.
6. At the prompt, type the following command string:
<Format>
Phlash16 /mode=3 [Driver label][File Name]
<Example>
Phlash16 /mode=3 A:\BIOS.WPH
7. The Phoenix Phlash16 Utility automatically updates the BIOS.
8. Restart the system after the utility completes the updating process.
Make sure you remove the oppy disk from the drive.
When you execute the Phlash16.exe. program and the screen displays
“Cannot ash if Memory Managers” error message, refer to the Appendix
to solve it.
