Type
Select [Auto] to automatically detect hard disk drive. If auto detection is successful, the BIOS Setup
automatically fills in the correct values for the remaining fields on this sub-menu. If the auto detection fails, it
may due to that the hard disk is too old or too new. If the hard disk was already formatted on an older system,
the BIOS Setup may detect incorrect parameters. In these cases, select [User] to manually enter the IDE hard
disk drive parameters.
LBA/Large Mode
This allows user to select the LBA/Large mode for a hard disk > 512 MB under DOS and Windows; for
Netware and UNIX user, select [Off] to disable the LBA/Large mode.

Set this item to [On] will enhance hard disk performance by reading or writing more data during each transfer.

Reporting Technology) feature, which can allow the hard disk to report, under some circumstances,
impending failures of the hard disk.
