Drive Parameters The first list in the left frame is for the drive parameters. The drive parameters are:
Parameter Description
Device Type of device, such as Hard Disk.
Vendor Manufacturer of the device.
Size The size of the device.
LBA Mode LBA (Logical Block Addressing) is a method of addressing
data on a disk drive. In LBA mode, the maximum drive
capacity is 137 GB.
Block Mode Block mode boosts IDE drive performance by increasing
the amount of data transferred. Only 512 bytes of data can
be transferred per interrupt if block mode is not used.
Block mode allows transfers of up to 64 KB per interrupt.
PIO Mode IDE PIO mode programs timing cycles between the IDE
drive and the programmable IDE controller. As the PIO
mode increases, the cycle time decreases.
Async DMA This indicates the highest Async DMA Mode that is
supported.
Ultra DMA This indicates the highest Sync DMA Mode that is
supported.
S.M.A.R.T.
Self-Monitoring Analysis and Reporting
Technology protocol used by IDE drives of some
manufacturers to predict drive failures.
Type This option sets the type of device that the AMIBIOS attempts to boot from after
AMIBIOS POST is completed. The settings are
Not Installed, Auto, CDROM, or ARMD.
The default setting is Auto . The Optimal and Fail-Safe default settings are Auto.
