3
Attach the connector at the other end of the cable
to the connector on the first IDE device; maintain
pin-1 orientation.
4
To connect a second IDE device, plug the middle
connector of the cable to the connector on the sec-
ond IDE device; maintain pin-1 orientation.
Keep these points in mind when installing IDE
devices:
■
For each IDE hard disk drive installed in your
computer, drive type and parameters must be
specified in the computer ’s CMOS setup. ATAPI
CD-ROM drives are not specified in the com-
puter ’s CMOS setup.
■
If your computer has only IDE hard disk drives,
or both IDE drives and SCSI drives, it always
boots from the IDE drive designated as drive C.
■
IDE hard disk drives larger than 528 MBytes may
require a disk partitioning utility for use under
DOS. The utility is usually available from the
drive manufacturer or the dealer.
■
If your computer has an ATAPI CD-ROM drive,
be sure the ATAPI CD-ROM driver (
adatapi.sys
)
is installed by running the Adaptec Installation
Manager.
Using Multiple IDE Controllers
Up to four IDE devices can be installed in your com-
puter by utilizing two IDE controllers. Keep these
points in mind when installing two IDE controllers:
■
One IDE controller must be designated as the pri-
mary and the other as the secondary. Typically, most
IDE controllers can be designated as the primary
only; however, the AMM-1525M/525M can be des-
ignated as either the primary or secondary. See IDE
Port Address (AMM-1525M/525M Only) on page 3.
■
Typically, the CMOS setup of most computers can
configure only two IDE hard disk drives con-
nected to the primary; however, some of the newer
computers can configure up to four IDE hard disk
drives connected to both the primary and second-
ary. See your computer’s documentation.
