The new BIOS file (e.g., newbios.bin) | |
The upgrade utility (awdflash.exe). |
Although you may conceivably use a different media for the files, this manual assumes that you are using a floppy disk.
Now you are ready to start the upgrade process.
WARNING! DO NOT interrupt the upgrade program while it runs! Interrupting the program leaves the system without a BIOS and unusable. If by some unlikely chance the power goes off during the few seconds the program requires to run, the system is left without a working BIOS and needs a correctly programmed flash EPROM installed.
If you are running the BIOS in an Intel 28F001BX-T flash memory chip, the 8K boot block area may retain its original code during the update process, depending on hardware settings (e.g., boot-block jumper setting).
Running the Program
NOTE: The Award flash utility cannot run when EMM386 or QEMM are loaded. If you try, an error message appears.
A screen similar to this appears:
