Examples of EISA/PCI Scan Order
Example 1:
PCI Slot 1 PCI SCSI controller, such as a 2940W
Drive at SCSI ID 0
EISA Slot 4 EISA RAID controller, such as a Mylex RAID 3 channel
Drive on Channel 1 SCSI ID 0
Drive on Channel 2 SCSI ID 4
Drive on Channel 3 SCSI ID 2
Assume for this example that the Mylex RAID controller ROM address is
defaulted to CC000h. Assume also that we have used the RAID
configuration utility to create a server logical drive 0. Given this example,
the Mylex RAID controller on the EISA bus would be scanned first, with a
ROM address of CC000h. The 2940W Adaptec controller on the PCI bus
would be scanned next. The 2940W requires 32 KB for initialization (even
though it only occupies 10 KB after optimization). As there is only 16KB
ROM address space between C8000h and CC000h, the 2940W would be
assigned the next 32KB block of ROM address space starting at D0000h.
The server logical drive 0 on the Mylex RAID controller would be the boot
device.
To boot from a bootable drive on the 2940W, the SCU would have to be
run to change the address of the Mylex RAID controller to a higher
address, such as D0000h, and then the SCU would assign C8000h to the
2940W, and that drive would become the boot device.
Example 2:
PCI Slot 1 PCI SCSI controller, such as a 3940W
Drive on Channel 1 SCSI ID 3
Drive on Channel 2 SCSI ID 1
PCI Slot 3 PCI SCSI controller, such as a 2940W
Drives at SCSI ID 1, 3
In this example, the scanning begins with PCI slot 1 (PCI bus 0) and the
3940W.
