Important notes / BIOS Extension ROM
For PCI cards with BIOS Extension ROM, there is a limited area of 64 KB available in the
Phoenix BIOS. A B&R PCI SATA RAID controller requires a free area of approx. 32 KB. The
remaining area can be used as desired.
If a PCI card requiring BIOS extension ROM is plugged into PCI slot 1 on an AP620 with 5 PCI
slots (see figure 70 "PCI slot numbering on APC620 systems with 5 PCI slots") and the B&R PCI
SATA RAID controller is plugged-in at a different position (e.g. PCI slot 4), then the BIOS menu
item
Advanced - PCI/PnP Configuration - PCI Device, Slot #2 must be set from " Option ROM
Scan " to " Disabled " so that this device can be used for booting. The BIOS default setting is to
always attempt to load the BIOS Extension ROM from the PCI slot 1. Alternatively, the two PCI
cards can be switched.
This setting does not have to be changed if a PCI card without BIOS extension ROM is plugged-
in.
Configuration of a PCI SATA RAID array
Instructions for configuration of a PCI SATA RAID array using RAID BIOS can be found in
chapter 3 "Commissioning", section "Configuration of a SATA RAID array", on page 253.
