P/I-P55SP4 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 scheme
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 17MB 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 full 32-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.
