1.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 P11 and P12
PCI slot P2 and P3 (first PCI bus)
Onboard 7895 SCSI (first PCI bus)
PCI slot P4 through P6 (second PCI bus)
PCI slot P7 through P10 (third PCI bus).
It’s recommended that the BIOS be disabled on all SCSI controllers except for the controller with the boot disk drive attached (see SCSISelect Utilities in Chapter 3, “ Configuring Your System”. This saves memory address resources and provides control over the boot device independent of board slot locations.
2.Additional IRQs 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.
3.A maximum of five LAN channels consisting of any combination of single or dual channel. Install ISA LAN card in the first available ISA slot from the top. Install PCI LAN card in the first available PCI slot from the top.
4.A maximum of four SCSI controllers may be installed. Install the first controller card in PCI slot P2 and the second controller in PCI slot P3.
