1. When more than 1 SCSI controller is plugged in, use IRQ 14 for secondary controller (non-booting
controller).
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:
ISA slots J3 through J6
PCI slot J11
Onboard 7880 SCSI
PCI slots J10
Onboard 7860 SCSI
PCI slot J9.
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 three LAN channels consisting of any combination of single or dual channel. Install
ISA LAN card in the first available ISA slot from the bottom. Install PCI LAN card in the first available
PCI slot from the top.
5. A maximum of two SCSI controllers may be installed. Install the first controller card in the top PCI slot
and the second controller in the second from the top PCI slot.
