1.PCI slot P10 is limited to short PCI option boards because of CPU #2.

2.For disk controllers plugged into slots and the onboard disk controllers, the sequence for BIOS scanning to determine the primary (Boot) disk controller is:

EISA slots P01 through P04

PCI slot P05 and P06 (primary PCI bus)

Onboard 7880 SCSI (primary PCI bus)

Onboard 7860 SCSI (primary PCI bus)

PCI slot P07 through P10 (peer PCI bus).

It is recommended that the BIOS be disabled on all SCSI controllers except for the controller with the boot disk drive attached (see The SCSISelect Utilities in the Configuring Your System chapter. This saves memory address resources and provides control over the boot device independent of board slot locations.

3.Additional IRQ’s can be made available as follows:

Disabling Comm Port 1 = IRQ4 is available Disabling Comm Port 2 = IRQ3 is available Disabling Parallel Port = IRQ7 is available.

4.A maximum of five LAN channels consisting of any combination of single or dual channel. Install EISA LAN card in the first available EISA slot from the bottom. Install PCI LAN card in the first available PCI slot from the bottom.

5.A maximum of two SCSI controllers may be installed. Install the first controller card in PCI slot P07 and the second controller in PCI slot P08.
