PCI/I-P54SP4
User's Manual
Faster Data Transfer
Enhanced IDE includes a scheme to support a significant increase
in the rate of data transfer from the IDE device to the rest of the sys-
tem compared to the previous standard. One aspect of this sc};leme
is support for the Mode 3 timing scheme. If you use both the on-board
controller and hard disks that support Mode 3 operation you can
increase the data transfer rate up to as much as 11MB per second.
Power Conservation
This mainboard incorporates the power conservation technology,
which you can set up in the BIOS Setup Utility, where the Power
Management Setup section controls the board's power management
scheme. The power management features include hard disk and
video controls. For more information see the section on Power Man-
agement Setup in Chapter 3.
SCSI BIOS Firmware & The Optional SC-200 Controller Card
This mainboard has on-board NCR SCSI firmware recorded in the
BIOS flash ROM chip that supports the NCR 53C810 PCI Fast SCSI-
2 controller. There is an optional SCSI controller card, the SC-200 that
uses this firmware. The NCR SCSI controller is a full32-bit PCI DMA
bus master and supports the ASPI and CAM standards.
You can connect a chain of up to seven devices to the SCSI inter-
face. The SC-200 SCSI interface card provides both internal and ex-
ternal connectors. There are details on this card and how to connect
SCSI devices to it at the end of Chapter 4.
Two floppy disks with support drivers come with the SC-200
card. There is detailed information about the drivers in "ReadMe"
files on the disks. There is more information about these disks in the
section on "SCSI BIOS & Drivers" in Chapter 3.
Upgrade Guide
This section explains how to install options on your mainboard.
It
covers the most likely and technically accessible upgrades you
might want to do, including adding expansion cards, increasing sys-
tem memory and adding IDE hard disks.
Installing upgrades will either improve the performance of your
computer, or add some additional capabilities to it. You can install
upgrades yourself, or have your dealer or a qualified computer tech-
nician do it for you.
It is also possible to increase the size of the Level2 cache, but since
this is a much more technically demanding upgrade that you are both
less likely to undertake and in most cases would probably require at
least partially disassembling your system, the technical reference in-
formation about it is in Chapter 4.
It
is probably best to have a quali-
fied technician perform the upgrade for you if you want to upgrade
the cache.
