AI5TV Motherboard User’s Manual 25
Primary HDDs / Secondary HDDs
The onboard PCI IDE connectors provide Primary and Secondary
channels for connecting up to four IDE hard disks or other IDE devices.
Each channel can support up to two hard disks; the first is the “Master”
and the second is the “Slave”.
To enter the specifications for a hard disk drive, you must select first a
“Type”. There are 45 predefined types and 4 user definable types for
Enhanced IDE BIOS. Type 1 to 45 are predefined. Type “User” is user-
definable. For the Primary Master/Slave as well as Secondary
Master/Slave, you can select “Auto” under the TYPE and MODE
fields. This will enable auto detection of your IDE drives and CD-ROM
drive during POST.
Press <PgUp>/<PgDn> to select a numbered hard disk type or type the
number and press <Enter> key. The hard disk will not work properly if
you enter improper information for this field. If your hard disk drive
type is not matched or listed, you can use Type User to define your own
drive type manually. If you select Type User, related information is
asked to be entered to the following items.
CYLS : Number of cylinders
HEAD : Number of read/write heads
PRECOMP : Write precompensation
LANDZ : Landing zone
SECTOR : Number of sectors
SIZE : Automatically adjust according to the configuration
MODE (for IDE hard disk only) : Auto
Normal (HD < 528MB)
Large (for MS-DOS only)
LBA (HD > 528MB and supports
Logical Block Addressing)
NOTE : The specifications of your drive must match with the drive table.
The hard disk will not work properly if you enter improper
information in these fields. If your hard disk drive type is not
matched or listed, you can use Type User to define your own
drive type manually.
