NOTE
Because each SCSI channel has its own span process running in parallel, the POST scan of SCSI
devices does not display in sequential order.
BIOS at 0x000C90000 – 0x000CE7FFF
Unlike ISA or EISA computers where the BIOS address of a peripheral expansion card is set
manually (ISA, jumpers) or with the help of a configuration file (EISA, cfg file) and the address
space is determined by the user, the PCI system-BIOS automatically maps the BIOS of a PCI
compatible peripheral expansion card to a memory address. At each cold or warm boot, it
determines which address space to assign to the BIOS of an expansion card. The message shown in
Figure 111 reports the physical address occupied by the Intel RAID Controller SRCU31
firmware BIOS.
[PCI 7/14]
PCI device, bus system 7, slot 14. The PCI 2.x specification allows several PCI bus systems to be
present in one PCI computer. All Intel RAID Controller SRCU31’s have been designed to support
multiple PCI bus system computers. The slot number indicated in the message above does not refer
to the 14th PCI slot, but indicates that the Intel RAID Controller SRCU31 is plugged into a slot
which is the 14th of the PCI chipset that the PCI computer can access. To determine which
physical PCI slot this corresponds to, consult the PCI computer system manual.
DPMEM (B) at 0xFA0000000 - 0xFA003FF INT A = IRQ 11
“DPMEM” stands for Dual Ported Memory. The Intel RAID Controller SRCU31 needs this
address space of the PCI computer for the command communication. As with the Intel RAID
Controller SRCU31 BIOS, this mapping is also automatically carried out by the PCI system-BIOS.
This information is essential when installing “Expanded Memory Managers” under DOS and
Windows. The Intel RAID Controller SRCU31 DPMEM address space has to be excluded from
the control of such a manager. Also, this message informs that the “PCI INT A” of the Intel RAID
Controller SRCU31 has been assigned to the system IRQ 11. This assignment is also carried out
automatically if the PCI system-BIOS is 100% PCI 2.x compatible.
SRCU31 – HWL0 -- 64 MB SDRAM / ECC - 2048KB Flash-RAM
“SRCU31 -- HWL0” stands for the type of Intel RAID Controller found by the Intel RAID
Controller SRCU31 firmware BIOS. (“HWL” means hardware level.) “64 MB SDRAM / ECC”
indicates that the installed DIMM is a 64 MB ECC SDRAM module. “2048 KB” indicates the size
of the installed Flash-RAM. Depending on the size of the installed RAM, the following messages
are possible (“xx” = 32, 64, 128, 256):
xx MB SDRAM/ECC
xx MB ECC-SDRAM-Module
async
SCSI devices are indicated as “async” until they have been initialized by the Intel RAID Controller
SRCU31.
