BIOS Configuration
Flash Writer Utility
The PhoenixBIOS Flash Writer Utility is now included in the PhoenixBIOS, and so it is
simpler to upgrade the BIOS of your mainboard. The system BIOS is stored on a flash
EEPROM ROM chip on the mainboard which can be erased and reprogrammed by
following the directions on the following page.
1. From the DOS prompt, rename the BIOS file that you have downloaded to
Phoenixboot.rom and copy it on to a floppy disk.
2. Insert the floppy disk with the BIOS upgrade into the A: drive.
3. Turn the power off.
4. Re-poweron the system and it will begin to read from the A: drive, and write the BIOS
information contained on the floppy disk in that drive to the EEPROM ROM chip. When
the BIOS has been totally reprogrammed, the system will reboot with the new BIOS in
operation.
5. If the system does not reboot in three minutes, power down the system wait a few
seconds, and then turn the power back on again. You will be prompted to press <F2> to run
Setup. You may check your settings at this time, or simply save and exit the program.

Beep Codes
Fatal errors, which halt the boot process, are communicated through a series of audible
beeps. There are only two beep codes that are associated with the Thunder 2500. Please
