User Binary Area

The baseboard includes an area in flash for implementation-specific OEM add-ons. This OEM
binary area can be updated as part of the system BIOS update or it can be updated
independent of the system BIOS.
The command line usage for the UbinD utility is as follows:
UBinD </R> or </I> or </D> [/M<ModID>] /F<RomFileName>
/B<NewUserBinaryFileName> [/N<NewRomFileName>] [/O<NCB>]
</R> - replaces the user binary module
</I> - inserts the user binary module
</D> - deletes the user binary module from the ROM file.
</?> - displays help information.
/M<ModID> - is hexadecimal user binary module ID; Default ModID = 0xF0.
/O<NCB> - is the 0-based index of the non-critical block number calculated from the start of the
ROM file. Default NCB = 1, used only with the insert option. See ROMInfo for reference.
</N<NewRomFileName> - if this option is not included, the ROM is saved with the same name.
3.5.4

Recovery Mode

Three conditions can cause the system to enter recovery mode:
•
Pressing a hot key: (<Ctrl+Home>)
•
Setting the recovery jumper (J4H1, labeled RCVR BOOT) to pins 1-2
•
Damaging the ROM image, which will cause the system to enter recovery and update
the system ROM including the boot block.
