Intel SE7520JR2 manual Flash Update Utility, Flash Bios, User Binary Area, Recovery Mode

Intel® Server Board SE7520JR2 System BIOS

The BIOS relies on specialized hardware and additional flash space to accomplish online update/rolling of the BIOS. To this end, the flash is divided into two partitions, primary and secondary. The active partition from which the system boots shall be referred to as the primary partition. The AMI FLASH update suite and Intel Online updates preserve the existing BIOS image on the primary partition. BIOS updates are diverted to the secondary partition. After the update is complete, a notification flag is set. During the subsequent boot following the BIOS update, the system continues to attempt to boot from the primary BIOS partition. On determining that a BIOS update occurred in the previous boot, the system then attempts to boot from the new BIOS. If a failure happens while booting to the new BIOS, the specialized hardware on the system switches back to the primary BIOS partition, thus affecting a “Roll Back”.

4.5.1Flash Update Utility

Server platforms support a DOS-based firmware update utility. This utility loads a fresh copy of the BIOS into the flash ROM.

The BIOS update may affect the following items:

•The system BIOS, including the recovery code, setup utility and strings.

•Onboard video BIOS, SCSI BIOS, and other option ROMS for the devices embedded on the server board.

•OEM binary area.

•Microcode updates.

4.5.1.1Flash BIOS

An afuXXX AMI Firmware Update utility (such as afudos, AFUWIN, afulnx, or AFUEFI) is required for a BIOS update.

4.5.1.2User Binary Area

The baseboard includes an area in flash for implementation-specific OEM add-ons. This OEM binary area can be updated as part of the system BIOS update or it can be updated independent of the system BIOS.

4.5.1.3Recovery Mode

Three conditions can cause the system to enter recovery mode:

•Pressing a hot key

•Setting the recovery jumper (J1H2, labeled RCVR BOOT) to pins 2-3

•Damaging the ROM image, which will cause the system to enter recovery and update the system ROM without the boot block.
