2.7 Primary (3.5") IDE connector (CN22)
The 40-pin IDE connector supports up to two 40-pin IDE interface
devices, including CD-ROM drives, tape-backup drives, HDDs, etc.
When connecting, make sure pin 1 of the connector is matched with pin
of the device's connector.
The built-in Enhanced IDE (Integrated Device Electronics) controller
supports up to two IDE devices, including CD-ROM drives, tape backup
drives, a large hard disk drive and other IDE devices. It also supports
faster data transfer rates and allows IDE hard disk drives with capacities
in excess of 528 MB.
2.7.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. Wire number 1 on the
cable is red or blue, while the other wires are gray.
Unlike floppy drives, IDE hard drives can connect to either end of the
cable. If you install two drives, you will need to set one as the master and
one as the slave by using jumpers on the drives. If you install just one
drive, set it as the master.
2.8 Secondary (2.5") IDE connector (CN20)
The on-board 44-pin mini-pitched IDE interface is used to let user sup-
port either a 2.5" HDD.
Follow the same connection arrangement as the 3.5" HDD if you want to
connect to a 2.5" IDE device. Read the BIOS setup section for more
information regarding system settings.
Note: You cannot use a DMA-66 HDD, due to the cable
is limitation.
