56 Keysight M9037A PXIe Embedded Controller User GuideController Maintenance BIOS SetupNormal BIOS Operation and UpdatesThe M9037A has two BIOS images, a Default and a Backup. The Default BIOS iswhat the system normally boots on, and is updatable by running a BIOS updatescript from a Windows console. Refer to “Updating the M9037A BIOS” onpage 66.However, if the Default BIOS becomes corrupt, the Baseboard ManagementController (BMC) detects that the Default BIOS was unable to boot, andre-configures serial connections to allow the Backup BIOS to boot the system. Allsubsequent boots will be from the Backup BIOS until the user repairs the DefaultBIOS using a provided tool from Keysight to restore the Default BIOS image tothe original shipping BIOS image.- Typically, all normal boots occur from the Default BIOS; the Backup BIOS isnot used.- Updates to the Default BIOS are done using BIOS update scripts fromKeysight which are based on American Megatrends (AMI) tools.- A BIOS update does not overwrite permanent SMBios data values (such asSerialNumber, BaseBoardVersion, UUID etc), but will clear the customerCMOS settings.Accessing the BIOS Setup UtilityTo start the BIOS setup program:1 Power on or reboot your M9037A controller.2 Press the <Delete> key when the controller beeps.
