Example: on most Emerson blades, the BIOS software is stored twice on a flash device, BIOS bank 1 and BIOS bank 2. The bank to boot from can be selected with the System Boot Options Control.

You have to select parameter 96 with the Boot Option Select Control and then set the BIOS 1

(0) or BIOS 2 (1) with the Boot Option Control.

The following example shows how to set BIOS 2 for a resource with the ID 120 using an example program which is delivered together with the HP-B development package:

hpibootoptions -r 120 96 1

The example program hpibootoptions, which is available in the base RPM package, shows how an option can be set or got.
