To create the Crisis Recovery Diskette insert a clean diskette into drive A: or B: and execute
WINCRISIS.EXE. This copies four files onto the Crisis Recovery Diskette:
MINIDOS.SYS
Allows the system to boot in Crisis Recovery Mode
PHLASH.EXE
Programs the flash ROM
PLATFORM.BIN
Performs platform-dependent functions
BIOS.ROM
Actual BIOS image to be programmed into flash ROM
If the BIOS image (BIOS.ROM) changes due to an update or bug fix, you can easily update the Crisis
Recovery Disk. Simply copy the new BIOS.ROM image onto the diskette.
You can run Phoenix Phlash in one of two modes:
•
Command Line Mode
•
Crisis Recovery Mode
Use the Command Line mode to update or replace your current BIOS. To execute Phlash in this
mode, move to the Crisis Recovery Disk and type PHLASH. Phoenix Phlash will automatically update
the BIOS. Phlash may fail if your system is using memory managers, in which case the utility will
display the following message:
Cannot flash when memory manager are present.
If you see this message after you execute Phlash, you must disable the memory manager on your
system!
8.4 Boot Block Support
Updating the BIOS may create a possible hazard: power failures or fluctuations that occur during
updating the Flash ROM can damage the BIOS code, making the system unbootable.
To prevent this possible hazzard the
MOPS/lcd6
is equiped 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 special crisis
diskette (see above).
Additionally the end user can insert an update key into the parallel port to force initiating the boot block
recovery routine.
For further information on the update key and the crisis diskette check the JUMPtec
web page.
