Multi-Sector Transfers Allows the System BIOS to read ahead by the specified
number of sectors during disk access. This has the effect
of reading more data at once to reduce the absolute
number of discrete disk reads performed by the operating
system, which may increase system performance.
You can select one of these:
• Disabled (default if no drive is installed)
• 2 Sectors
• 4 Sectors
• 8 Sectors
• 16 Sectors (default if a drive is installed)
Note: Autotyping may change this value if the hard disk
reports that it supports block accesses.
LBA Mode Control Determines how the System BIOS references hard disk
data. You can use this option only if both the hard disk
being configured and the operating system support
Logical Block Addressing (LBA). Autotyping may change
this value if the hard disk reports that it supports LBA.
You can select one of these:
• Disabled (default if no drive is installed): Reference
hard disk data using the Cylinders/Heads/Sectors (CHS)
method.
• Enabled (default if a drive is installed): Reference hard
disk data as logical blocks.
32-bit I/O Determines how the System BIOS accesses the hard disk
controller. Autotyping does not affect this option.
Accesses with 32-bit I/O accesses. This option increases
system performance.
You can select one of these:
• Disabled: Select this option if an ISAbus IDE controller
is installed in the system.
• Enabled: Select this option to maximize system
performance when the onboard PCI IDE controller is
used.
