BIOS FWH Boot Selection (SWX2)

Set Pin 3 of switch SWX2 to determine whether the AMC-1000

boots from BIOS1 or BIOS2 FWH. Setting the module to boot from

BIOS2 FWH effectively makes BIOS2 the default FWH.

Use this setting if it is necessary to update the contents of the

BIOS2 FWH (see “BIOS Update Procedure” on page 35). Be sure

to set the module to boot from the BIOS1 FWH after the BIOS2

FWH update procedure has been completed.
