BIOS Flash utility
Use the BIOS flash memory update for the following conditions:
❑ New versions of system programs (such as HDD_PW or bios_pw).
❑ New BIOS features or options.
❑ Restore a BIOS when it becomes corrupted.
Use the Phlash utility to update the system BIOS flash ROM.
Note: If you do not have a crisis recovery diskette at hand, then you should
create a Crisis Recovery Diskette before you use the Phlash utility. For
more information about creating a Crisis Recovery Diskette, see
“Creating a Crisis Diskette” on page 159
Note: Do not install memory-related drivers (XMS, EMS, DPMI) when using
Phlash.
Caution: Use the AC adapter power supply when you run the Phlash utility.
If the battery pack does not contain enough power to finish flashing
the BIOS, the notebook may not boot because the BIOS was not
completely loaded.
To use Phlash:
1 Create a bootable diskette.
2 Copy the flash utilities to the bootable diskette.
3 Boot the notebook from the bootable diskette. The pflash utility runs
automatically.
