BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can easily upgrade the BIOS
without having to disassemble the system. The flash upgrade process can be done by
running a utility from a diskette or hard disk, or over a network.
WARNING
For information about the latest BIOS update for the Gatineau, contact your
service representative.
Expansion Slots
This motherboard has two 16-bit ISA slots, four PCI expansion slots and one AGP slot.
PCI Slots:
The PCI bus transfers data at 132 MB/second. Part of the reason for high transfer rates
is the PCI bus can operate concurrently with the processor bus; it doesn’t override it.
The CPU can be processing data in an external cache while the PCI bus is busy
transferring information between other parts of the system. Another key feature of the
PCI bus is it’s plug and play capabilities. This eliminates the need for jumper and dip
switches for configuring a PCI card.
The PCI slots on the Gatineau motherboard are numbered 1-4, with 1 being closest to
the AGP slot. All PCI slots are fully functional bus-mastering slots.
PCI 1:
This slot shares the PCI Interrupt used by the AGP slot.
PCI 2:
This slot shares the PCI Interrupt used by the integrated on-board sound
PCI 3:
This slot shares the PCI interrupt used by the integrated on-board LAN.
PCI 4:
This slot does not share the PCI interrupt with any slots and on-board devices.
Hardware Monitor
The optional hardware monitor subsystem provides the instrumentation capabilities.
The features of the hardware monitor subsystem include:
• Support for an optional chassis intrusion sensor or mechanical switch.
• An integrated ambient temperature sensor.
