If

is selected, the other options on the bottom portion of this screen do not display.
LBA/Large Mode
This option allows you to enable IDE LBA (Logical Block Addressing) Mode for the specified
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.
The Setup screen displays the system option:
LBA/Large Mode [Auto]
Two options are available:
Select
Disabled
to have AMIBIOS use the physical parameters of the hard disk and do
no translation to logical parameters. The operating system which uses the parameter table
will then see only 528MB of hard disk space even if the drive contains more than
528MB.
Select
Auto
to enable LBA mode and translate the physical parameters of the drive to
logical parameters. LBA Mode must be supported by the drive and the drive must have
been formatted with LBA Mode enabled.
Block (Multi-Sector Transfer) Mode
This option supports transfer of multiple sectors to and from the specified IDE drive. Block mode
boosts IDE drive performance by increasing the amount of data transferred during an interrupt.
If
Block Mode
is set to
Disabled
, data transfers to and from the device occur one sector at a time.
The Setup screen displays the system option:
Block (Multi-Sector Transfer) [Auto]
Available options are:
Disabled
