System BIOS Upgrade Procedure
The notebook supports EPROM Flash BIOS that allows you to easily update the
system BIOS using the Phoenix BIOS Flash utility program called
PHLASH.COM. This program runs under DOS and so it doesn’t load high
memory like HIMEM.SYS. It also needs the PLATFORM.BIN file to activate.
Follow these steps to update the system BIOS:
1.
Prepare a clean bootable diskette without loading the HIMEM.SYS. Copy
the files PHLASH.COM and PLATFORM.BIN into the diskette along with
the BIOS ROM file.
2.
Restart the computer and boot from the diskette. At the DOS prompt, enter
the command PHLASH <BIOSfile.ROM> to activate Flash BIOS
programming utility. The computer then starts to update the system BIOS
inside the notebook.
3.
After programming is complete, the system prompts you to press any key to
shutdown the computer. Power on again and check the BIOS version and
date code. The BIOS version and date code is shown on the Reference ID
and Manufacturer ID during power on display.
Reference ID : 10-112-3015
Manufacturer ID : 0915-1200A
n
The first two numbers of the Reference ID is the number version (1.0)
while the last letter of the Manufacturer ID is the letter version (A). So
the BIOS version is 1.0A.
n
The first four numbers of the Manufacturer ID denotes the BIOS date –
09/15 or September 15.
CAUTION
It is very important not to power off the system when the
FLASH BIOS program is running. Otherwise, the system
may not be able to power on and you will need to replace
the BIOS EPROM chip from another working notebook
system.
