4. If the BIOS image (BIOS.ROM) changes due to an update or
bug fix, copy the new BIOS onto the diskette and name it
BIOS.ROM.
Phoenix Phlash runs in either command line mode or crisis
recovery mode.
5. Use the command line mode to update or replace a BIOS. To
execute Phlash in this mode, move to the Crisis Recovery
Disk and type:
PHLASH16 <bios name>
(Example: PHLASH16 LEUBR110.WPH)
PhoenixPhlash will update the BIOS. PhoenixPhlash can
fail if the system uses memory managers. If this
occurs, the utility displays the following message:
Cannot flash when memory manager are present.
If you see this message after you execute Phlash,
disable the memory manager or use parameter /x for
Phlash16.exe.
PHLASH16 /X <bios name>
Preventing Problems When Updating or Restoring
25.10.2
BIOS
Updating the BIOS represents a potential hazard. Power failures
or fluctuations can occur when you update the Flash ROM can
damage the BIOS code, making the system unbootable.
To prevent this hazard, many systems come with a boot-block
Flash ROM. The boot-block region contains a fail-safe recovery
routine. If the boot-block code finds a corrupted BIOS (checksum
fails), it boots into the crisis recovery mode and loads a BIOS
image from a crisis diskette (see above).
Additionally, the end user can insert an update key into the
parallel port (LPT) to force initiating the boot block recovery
routine.
