Hard Disk Detect
IDE HDD Auto Detection
The “IDE HDD Auto Detection” option detects the parameters of an IDE hard disk
drive, and automatically enters them into the Standard CMOS Setup screen.
Up to four IDE drives can be detected, with parameters for each listed inside the box.
To accept the optimal entries, press <Y> or else select from the numbers displayed
under the OPTIONS field (2, 1, 3 in this case); to skip to the next drive, press <N>. If
you accept the values, the parameters will appear listed beside the drive letter on the
screen. The process then proceeds to the next drive letter. Pressing <N> to skip rather
than to accept a set of parameters causes the program to enter zeros after that drive
letter.
Remember that if you are using another IDE controller that does not feature Enhanced
IDE support for four devices, you can only install two IDE hard disk drives. Your IDE
controller must support the Enhanced IDE features in order to use Drive E and Drive
F. The onboard PCI IDE controller supports Enhanced IDE, with two connectors for
connecting up to four IDE devices. If you want to use another controller that supports
four drives, you must disable the onboard IDE controller in the Chipset Features Setup
screen.
When auto-detection is completed, the program automatically enters all entries you
accepted on the field for that drive in the Standard CMOS Setup screen. Skipped
entries are ignored and are not entered in the screen.
If you are auto-detecting a hard disk that supports the LBA mode, three lines will
appear in the parameter box. Choose the line that lists LBA for an LBA drive. Do not
select Large or Normal.
The auto-detection feature can only detect one set of parameters for a particular IDE
hard drive. Some IDE drives can use more than one set. This is not a problem if the
drive is new and empty.
