BIOS recovery
WARNING! Do not upgrade the BIOS unless your system has a BIOS-related issue.
Flashing the wrong BIOS can cause irreparable damage to the system. In no event shall
RadiSys be liable for direct, indirect, special, incidental, or consequential damages arising
from a BIOS update. If you need to update the BIOS, do not shut down or reset the
system while the BIOS is updating. This is to avoid possible boot failure.
How to recover the AMIBIOS image
An AMIBIOS flash chip consists of a boot sector block and a main BIOS code block (a main
BIOS image). The boot sector block contains critical BIOS code, including memory detection
and recovery code, to be used to flash a new BIOS image if the original BIOS image is
corrupted. When the system is powered on, the boot sector code executes first. Once it is
completed, the main BIOS code continues with system initialization and completes the bootup
process.
Note: The BIOS recovery described below is used when the main BIOS block crashes. However,
when the BIOS boot sector crashes, you will need to send the motherboard back to RadiSys for
RMA repairs.
Boot sector recovery from a USB device
This feature enables you to recover a BIOS image using a USB device (no additional utilities
required). You can download the BIOS image into a USB flash device and name the file
“SUPER.ROM” for the recovery process to load the file. A USB flash device such as a USB flash
drive, a USB CDROM or a USB CDRW device can be used for this purpose.
1. Insert the USB device that contains the new BIOS image (the ROM files) saved in a root
directory into your USB drive.
2. While turning the power on, press and hold the Ctrl and Home keys until the USB Access
LED Indicator comes on. This might take a few seconds.
3. Once the USB drive LED is on, release the Ctrl and Home keys. AMIBIOS issues beep codes
to indicate that the BIOS ROM file is being updated.
4. When BIOS flashing is completed, the computer reboots. Do not interrupt the flashing
process until it is completed.
Boot sector recovery from an IDE CD-ROM
This process is almost identical to the process of boot sector recovery from a USB device, except
that the BIOS image file is loaded from a CD-ROM. Use a CD-R or CD-RW drive to burn the
BIOS image file to a CD, and name the file “SUPER.ROM” for the recovery process to load the
file.
