Intel® Server Board SE7520BD2 Technical Product Specification 

BIOS Architecture 

Revision 1.3 

Intel Confidential

ID 

Feature Name 

Comments 

 

Hardware support for monitoring: Voltages, 
Temperature, Fans 

BMC will support it. 

 

BIOS Setup will provide options to disable onboard I/O 
Peripheral components 

(LAN components, Serial ATA, SCSI, etc.). When 
disabled, these components are to be completely 
removed from the PCI Address space, making them 
invisible to any loaded O/S 

Must be able to disable embedded 
video (ATI RAGE* XL), SCSI (LSI* 
53C1030), ICH5-R serial ATA, and 
NIC (Intel® 82541PI and Marvell* 
“Yukon” 88E8050) controllers. 

 

BIOS Setup will provide options to disable/enable 
optional ROMs of onboard devices and PCI slots. 

Enable/disable optional ROMs by 
BIOS setup. 

 

Ability to store error events in non-volatile space 

System stores events via BMC.  

 

Rolling BIOS – stores two versions of the BIOS on the 
board – possible to fail over if one bios is corrupted 

 

 

Support for Spilt Option ROM based on PCI-SIG PCI 
Firmware Specification Revision 3.0 

 

 

On line BIOS update capability: Ability to update BIOS 
(or FW) while OS is up.  Update takes effect at next 
reboot. 

 

 SUP 

Utility 

Support for SUP Utility must exist starting at Beta and 
through production to allow easy updates of BMC/HSC 
FW, FRU/SDR and BIOS 1)  

1) Ability to update all SW/FW in a single batch 
process, with one reboot at the end of the process.  

2) Ability to do # 1 after booting to a PXE server where 
the BMC+HSC+FRU/SDR+BIOS update files are 
stored. 

3) Ability to do # 1 after booting locally to a floppy 
diskette and then mapping to a shared network drive 
where the BMC+HSC+FRU/SDR+BIOS update files are 
stored. 

4) Current ability to do # 1 from hard drive, and CD-
ROM drive needs to be maintained. 

 

 

Active thermal management to minimize noise at the 
system level.  Should adhere to the acoustic section of 
the Blue Angel specification 

Supported via BMC 

 

Factory Automation support required. This includes the 
ability to upgrade/update FW, BIOS, CMOS settings, 
OEM splash screen image, FRU/SDR and HSC code 
remotely (over a LAN) using automated tools in a 
volume production environment.  

 

 NMI 

detection 

Ability to detect parity/system errors on all PCI buses  

Ability to detect single/multiple bit error 

 

 

Support for Sleep button 

 

 

Support for clear password by jumper 

 

 

Support for clear CMOS by jumper 

 

 

Support for IPMI 2.0/1.5 

Mini BMC (1.5 compliant) or server 
module card (Intel Sahalee(2.0 
compliant)) 

 

Support for Intel diagnostic LEDs 

 

 

Support for serial console redirection
