ATA (PI) 80-Pin Cable Detection
This function is used to select the method used to detect the ATA (PI) 80-pin cable.
Optimal and Fail-Safe default settings: Host & Device
The use of an 80-conductor ATA cable is mandatory for running Ultra ATA/66, Ultra ATA/100
and Ultra ATA/133 IDE hard disk drives. The standard 40-conductor ATA cable cannot handle
the higher speeds.
The 80-conductor ATA cable is plug-compatible with the standard 40-conductor ATA cable. Be-
cause of this, the system must determine the presence of the correct cable.
This detection is achieved via an open in the host connector in one of the lines on the 80-con-
ductor ATA cable that is normally an unbroken connection in the standard 40-conductor ATA
cable. It is this break that is used to make this determination. The BIOS can instruct the drive
to run at the correct speed for the cable type detected.
SETTING DESCRIPTION
Host & Device Use this setting when both the motherboard onboard IDE controller and the IDE disk drive
are to be used to detect the type of IDE cable used.
Host Use this setting when the motherboard onboard IDE controller is to be used to detect the
type of IDE cable used.
Device Use this setting when the IDE disk drive is to be used to detect the type of IDE cable used.
