Chapter 2: BIOS information
2.3.4 Primary/Secondary IDE Master/Slave
While entering Setup, BIOS auto-detects the presence of IDE devices. There is a
separate sub-menu for each IDE device. Select a device item then press Enter to
display the IDE device information.
The values opposite the dimmed items (Device, Vendor, Size, LBA Mode, Block Mode,
PIO Mode, Async DMA, Ultra DMA, and SMART monitoring) are auto-detected by
BIOS and are not user-configurable. These items show N/A if no IDE device is
installed in the system.
Type [Auto]
Selects the type of IDE drive. Configuration options: [Auto] [Not Installed]

Enables or disables data multi-sectors transfers. When set to Auto, the data
transfer from and to the device occurs multiple sectors at a time if the device
supports multi-sector transfer feature. When set to Disabled, the data transfer from
and to the device occurs one sector at a time. Configuration options: [Auto]
[Disabled]
