sector size by boosting the write current for sectors on inner tracks. This parameter designates the track (cylinder) number where write precompensation begins.

Sectors (Sec) designates the number of disk sectors per track.

Size is the formatted capacity of the drive (in megabytes) based on the following formula:

# of heads x # of cylinders x # of sects/cyln x 512 bytes/sect

IDE Drive Type Setup Options

For each of the four hard disk drives which is an IDE drive, the following options are also available for the drive:

Logical Block Addressing (LBA) Mode

This option allows you to enable IDE LBA (Logical Block Addressing) Mode for the specified primary or secondary IDE drive. Data is accessed by block addresses rather than by the traditional cylinder-head-sector format. This allows you to use drives larger than 528MB.

If LBA Mode is set to On and is supported by the hard disk drive, and if the drive is formatted, AMIBIOS enables LBA mode and translates the physical parameters of the drive to logical parameters. If a hard disk drive which supports LBA mode and has a capacity greater than 528MB was formatted with LBA mode disabled, AMIBIOS does not enable LBA mode even if the LBA Mode parameter is set to On in Standard CMOS Setup.

If LBA Mode is set to Off, AMIBIOS uses the physical parameters of the hard disk and does not translate parameters. The operating system which uses the parameter table then sees only 528MB of hard disk space even if the drive contains more than 528MB.

Available options are:

Off

On

Block (Blk) Mode

This option supports transfer of multiple sectors to and from the specified primary or secondary IDE drive.

Block mode boosts IDE drive performance by increasing the amount of data transferred during an interrupt. Block mode allows transfers of up to 64KB per interrupt, whereas only 512 bytes of data can be transferred per interrupt if block mode is not used.

If Block Mode is set to On and is supported by the IDE drive, AMIBIOS enables multi- sector transfers. AMIBIOS sets the number of sectors to be transferred per interrupt to the value returned by the "identify drive" command.
