Intel SE7520JR2 9.4BIOS Recovery Operation

Miscellaneous Board Information Intel® Server Board SE7520JR2

Clear state and power the system up. This feature can be enabled or disabled via the CMOS Clear Options command.

The following sequence of events must occur to invoke the Control Panel CMOS Clear feature.

1.Standby power must be on, system power must be off, and the feature enabled.

2.The control panel reset button must be pressed and held for at least 4 seconds

3.With the control panel reset button still pressed, the control panel power button must be pressed

The IMM Sahalee BMC produces a single beep through the system speaker to confirm the CMOS clear button sequence.

The Sahalee BMC does not assert the CMOS Clear hardware signal. BIOS checks for BMC CMOS Clear state (using the CMOS Clear Options command) at each boot to determine if the Sahalee BMC is requesting a CMOS Clear operation. The BMC CMOS Clear state remains active until one of the following events occurs:

It is forced off using a CMOS Clear Options command (this is the normal operational case, by BIOS).

The reset button is pressed.

The power button is pressed and released. The system is powered off.

9.4BIOS Recovery Operation

The BIOS Recovery Operation should be attempted if for any reason the BIOS gets corrupted causing the system to hang at POST generating a CMOS error. Should the system exhibit POST hangs due to BIOS corruption, you should:

Option 1) cycle power.

This option will perform 1 of 2 possible operations. The reboot may clear possible BIOS corruption with the Primary BIOS image and the system will boot normally. If the Primary BIOS image is non-correctable, the system will perform an Auto Recovery which loads the secondary or backup BIOS image. If this option is not successful and your system continues to exhibit CMOS corruption errors, you can attempt option 2.

Option 2)

•Obtain BIOS Update Package From the following Intel Web Site: :http://support.intel.com/support/motherboards/server/se7520jr2/

•Turn off the system

•Verify the jumper on jumper block J1A4 is set to Pins 1-2.

•Build Recovery Storage Media using files compressed in the RECOVERY.ZIP file

•Recovery from USB Disk-on-key or other large media

oPrepare a formatted and bootable storage media device such as a USB DISK_ON_KEY.

oCopy AMIBOOT.ROM to it.
