4.2 Update and Recovery
This section describes how to update the code and data held in the BIOS ROM. The process should
be undertaken with care and must not be interrupted. A recovery mechanism is also described that
enables a corrupted BIOS ROM (as a result of an interrupted update, for example) to be repaired.
Updates are available online from the RadiSys site in the form of a compressed image (ZIP) of a
number of files. Using the software contained in the ZIP file, you must first create a flash diskette
that is then used for the update or recovery process. Included in the ZIP file is a ‘Readme.txt’ file
that contains information on the update and instructions on how to use it. Always read this
document before proceeding as it may contain updates to the descriptions below.
The update process assumes you have a PC that can be used to create an update diskette and that
the system to be updated or recovered has a diskette drive attached.
Updating the BIOS is a process that should be undertaken with caution. Always complete
the process before powering-down or restarting the motherboard – failure to do this may
result in a corrupted BIOS that will require recovery.
4.2.1 Creating a BIOS Update Diskette
Follow the steps below. You need a PC with Microsoft MS-DOS, Windows 95 or Windows 98 and a
blank diskette.
". Obtain the update ZIP file from the Manuals, Drivers & BIOS section on the RadiSys web
site, www.radisys.com.
2. Unzip the contents to an empty directory on your hard drive.
3. Insert a blank diskette into the floppy drive.
4. Run CRISDISK from the directory created in step 2 to create the update diskette
5. Follow the steps as directed. A copy of MS-DOS ‘Format.com’ must be available for
CRISDISK to complete successfully.
4.2.2 Updating the System BIOS
The system BIOS can be updated from MS-DOS without changing jumpers as described below. It is
recommended that you create a recovery diskette (described later) before updating the BIOS. This
operation does not affect the customization area in the BIOS. If you use the BIOS Setup utility
CMOS Save and Restore functions to save a set of defaults, you will need to recreate and re-save
these once the update is complete.
". Create an update diskette as described above.
2. Boot the system to be updated into MS-DOS without memory managers or boot from the
update diskette.
3. If you did not boot from the update diskette, do the following.
A. Insert the update diskette into the floppy drive.
B. Change the MS-DOS directory to match the floppy drive’s directory.
C. Type UPDATE and press Enter.
4. Follow the instructions to initiate the update. When it is finished, the following message
appears:
Flash memory has been successfully programmed
PRESS ANY KEY TO RESTART THE SYSTEM
If the system does not restart
TURN THE POWER OFF, THEN ON
5. Turn off the system power and re-boot. The motherboard will boot using RadiSys defaults.
