4. If the BIOS image (BIOS.ROM) changes because of 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 the BIOS. To execute Phlash in
this mode, move to the Crisis Recovery Disk and type:
PHLASH16 <bios name>
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 BIOS

24.10.2.
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.
For further information on the update key and the crisis diskette, see the Application Note
PHLASH_SCE???, which is available from the KONTRON Embedded Modules Web site. The three
question marks stand for the revision number of the file.
