IDE HDD Auto-Detection
Automatic detection of the hard disk is initiated by pressing the <Enter> key. After a few seconds the
physical data of the connected hard disk should be displayed in the lower section of the menu.
IDE Channel 0 Master
This parameter is used for configuring the IDE bus. The following options are available:
• None (no hard disk connected to this bus connection)
• Auto (auto-detection during each boot process)
• Manual (the hard disk is addressed with the set parameters)
Access Mode
This option can be used to select the operating system for the hard disk. Setting options: CHS, LBA, LARGE,
or Auto. Auto is the recommended setting. Normal (standard) mode supports hard disks with a capacity of up
to 528 MB. This mode uses positions for data access that are specified via cylinders (CYLS), heads, and
sectors. The older LBA (Logical Block Addressing) mode can support hard disks with a capacity of up to 8.4
GB. This mode uses a different method for calculating the position disk data to be accessed. It translates
cylinders, heads and sectors into a logical address for the data location. Large hard disks support this mode.
The BIOS supports the INT 13h extension function that enables the LBA mode to manage hard disk drives
with a capacity of more than 8.4 GB. If the number of cylinders (CYLs) on the hard disk exceeds 1024 and
DOS cannot support it, or if your operating system does not support LBA mode, LARGE mode should be
selected. The following options are available for setting the hard disk access mode:
• CHS
• LBA
• LARGE
• Auto
The following parameters are automatically determined and displayed.
Capacity
Storage capacity of the hard disk. This value is calculated from the individual hard disk parameters.
