IDE Connector (CC)
This is an integrated Ultra-DMA PCI/IDE interface with an IDE connector
capable of controlling up to two IDE devices. Ultra-DMA provides faster
access to IDE devices that are Ultra-DMA compliant while maintaining
support for IDE devices that do not support the Ultra-DMA specification.
capable of controlling up to two IDE devices. Ultra-DMA provides faster
access to IDE devices that are Ultra-DMA compliant while maintaining
support for IDE devices that do not support the Ultra-DMA specification.
The IDE controller supports:
•
PIO and IDE DMA/bus master operations
•
Mode 4 timings
•
Transfer rates up to 33 MB/sec
•
Buffering for PCI/IDE burst transfers
•
Master/slave IDE mode
•
Up to two drives for one IDE channel
Diskette Drive Connector (DD)
The diskette drive controller and connector on the system board can support
up to two diskette drives of 1.44-MB and 2.88-MB formats.

System Jumpers (B)
These jumpers allow you to set certain characteristics of the system. Some
jumpers are reserved and are not described in this section. Do not change
any jumper unless it is necessary to configure the system. In some cases,
changing the settings of reserved jumpers can cause damage to the system
board.

Clear CMOS Jumper
This jumper allows you to clear the complimentary metal-oxide
semiconductor (CMOS) memory. You should only do this if you cannot
access the normal methods of modifying the CMOS and modifications to
the CMOS are necessary. Clearing CMOS memory returns all BIOS Setup
settings to the default values. This jumper occupies pins 1-3 of the
connector. See “Setting the Jumpers” on page 72 for more information on
setting the CMOS clear jumper.

Note:
You can connect an IDE
signal cable, up to a
maximum of 18 inches, to
the IDE connector on the
system board. The cable
can support two devices,
one at the end of the cable
and one six inches from the
end.
