Console 2 OpROM.
Console 2 OpROM.
2.3.3
Boot Strap ROM (SEEPROM)
The serial bootstrap ROM is used to configure the LSI*SAS2108 ROC before the server board
configures the PCI Express* registers. The bootstrap ROM sets the Phase Lock Loop (PLL)
dividers, bootstrap configuration, and so on.

2.3.4
NVSRAM
A 32-KB NVSRAM is used to store disk and drive setup information.
2.3.5
SDRAM (Cache)
The Intel
®
RAID Controller RS2BL080 includes 512 MB of integrated DDR2 800 MHz ECC
SDRAM memory. This DIMM is connected directly to the memory controller interface bus of the
ROC and serves as storage for the executable code transferred from the flash. It also serves as
cache during RAID transactions. Cache mode selection takes immediate effect while the server
is online and is available on a per virtual drive basis. The ROC memory controller provides
single-bit ECC error correction with multi-bit detection support.
