Chapter 3: BIOS Setup
Type
Selects the type of IDE drive connected to the system.
LBA/Large Mode
Auto The LBA mode will automatically be enabled, that is, if the
LBA mode was not previously disabled.
Disabled Disables the LBA mode.
Block (Multi-Sector Transfer)
Auto Data transfer to and from the device occurs multiple sectors at
a time.
Disabled Data transfer to and from the device occurs one sector at a
time.
PIO Mode
Selects the data transfer mode. PIO means Programmed Input/Output.
Rather than have the BIOS issue a series of commands to effect a transfer
to or from the disk drive, PIO allows the BIOS to tell the controller what
it wants and then let the controller and the CPU perform the complete
task by themselves. Your system supports five modes, 0 (default) to 4,
which primarily differ in timing. When Auto is selected, the BIOS will se-
lect the best available mode after checking your drive.
Auto The BIOS will automatically set the system according to your
hard disk drive's timing.
Mode 0-4 You can select a mode that matches your hard disk drive's
timing. Caution: Do not use the wrong setting or you will
have drive errors.

for ATA/IDE and SCSI drives. The drive will provide sufficient notice to
the system or user to backup data prior to the drive's failure. SMART is
supported in ATA/33 or later hard drives. The options are Auto (default),
Enabled and Disabled.
