IDE Primary Slave
This menu is used to set the data for the hard disk connected as master to the first IDE bus. The hard disk data (size,
number of cylinders, heads, sectors, pre-compensation and home position of the heads when the disk is switched off)
are displayed automatically for the connected hard disk.

IDE HDD Auto-Detection:
Automatic detection of the hard disk is initiated by pressing the
the connected hard disk should be displayed in the lower section of the menu.
IDE Primary 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
