4-16 Chapter 4: BIOS setup
Before attempting to configure a hard disk drive, make sure you have
the correct configuration information supplied by the drive manufacturer.
Incorrect settings may cause the system to fail to recognize the
installed hard disk.
4.3.4 Primary and Secondary IDE Master/Slave
While entering Setup, the BIOS automatically detects the presence of IDE
devices. There is a separate sub-menu for each IDE device. Select a device
item then press to display the IDE device information.
The BIOS automatically detects the values opposite the dimmed items
(Capacity, Cylinder, Head, Sector and Transfer Mode). These values are not
user-configurable. These items show N/A if no IDE device is installed in the
system.
Primary IDE Master/Slave [Auto];
Secondary IDE Master/Slave [Auto]
Select [Auto] to automatically detect an IDE hard disk drive. If automatic
detection is successful, the BIOS automatically fills in the correct values
for the remaining fields on this sub-menu. If the hard disk was already
formatted on a previous system, the setup BIOS may detect incorrect
parameters. Select [Manual] to manually enter the IDE hard disk drive
parameters. If no drive is installed select [None].
Configuration options: [None] [Auto] [Manual]
Access Mode [Auto]
The default [Auto] allows automatic detection of an IDE hard disk drive.
Select [CHS] for this item if you set the IDE Primary Master/Slave to
[Manual]. Configuration options: [CHS] [LBA] [Large] [Auto]
