10.1 BIOS Configuration
See Chapter 7, “BIOS Features,” for BIOS configuration options and Chapter 8, “BIOS Setup,” for
information about using the BIOS Setup program. See Section 2.2.3.1, “Memory Ordering Rule for
the MCH” on page 20 for information about installing DIMMs.
10.2 BIOS Image Updates
At times, new BIOS images will be released to add additional features to the SBC. The release
package contains the flash utility, which comes in two versions. They are "flashdos" for DOS and
"flashlnx" for Linux OS. The package also contains the BIOS ROM image. Below is a step-by-step
procedure on how to update the BIOS:
1. Copy the flash utility and the Pxx-xxxx.rom file to a DOS bootable floppy disk.
2. Boot MPCBL0001from a USB floppy disk (connected to the USB port) to a DOS prompt.
3. Copy flash utility and BIOS ROM image to RAM disk, which is automatically generated
(C: drive).
4. Issue the command "flashdos /b Pxx-xxxx (xx= build type version, xxxx=build identifier).
5. Enter "Y" to overwrite the BIOS on the board.
6. Enter "Y" to clear the current COMS settings on the board.
7. Enter "Y" to reboot the system after the BIOS has been upgraded successfully.
10.3 Procedures to Copy and Save BIOS (Including
CMOS Settings)
The CMOS settings, together with the BIOS binary image, can be copied to a file with a file name
specified by the user.
10.3.1 Copying BIOS.bin from the SBC
1. Copy the flashlnx utility to the SBC running MontaVista* Carrier Grade Linux*. (This SBC is
the one with custom CMOS settings that will be used to update other SBCs.)
2. Issue the command “./flashlnx -r -afff20000 -s917504 BIOS.bin” to copy the BIOS with the
customized CMOS settings to the same directory from which flashlnx is executed. All user-
preferred settings (including the BIOS image) will be saved in the file named BIOS.bin.
Note: “BIOS.bin” is a generic file name used here to illustrate the command line used to perform the
operation. The user may wish to use the BIOS version (e.g., P08-0021.bin) as the file name instead
of BIOS.bin.
