The BIOS Setup Utility
4-5
Do not adjust the rest of the settings unless absolutely necessary. The BIOS
automatically enters the optimal settings.
Type
This category selects the drive type installed in the system. The options are
1-39, User, and none. It is doubtful you will find your drive in 1-39.
If Autotype Fixed Disk does not find your drive’s parameters, fill this
information in manually under the User category. This information may be
in the manual which came with your system. If not, contact your dealer or
the hard drive manufacturer to fill in this category.
If you are using a SCSI hard drive, select None and refer to the documenta-
tion which came with the SCSI adapter.

This category determines the number of sectors per block for multiple sector
transfers. The options are Disabled (default), 2 Sectors, 4 Sectors, 8 Sectors,
and 16 Sectors.
LBA Mode Control
Enable LBA (Logical Block Addressing) to support IDE drives larger than
528MB in size. The default setting is Disabled.
32-Bit I/O
This category allows the user to enable the 32-bit I/O function of the PCI IDE
controller. Select Disabled if your drive will not run at this speed. The
default setting is Enabled. This option is not available on ISA IDE Adapter
