Chapter 4: BIOS configuration

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 : This field displays only when the Type field contains a
value of [User] or [1–39]. 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 LBA
(Logical Block Addressing). 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 CHS (Cylinders/Heads/Sectors)
method.
• Enabled (default if a drive is installed) : Reference hard
disk data as logical blocks.
Note : This field displays only when the Type field contains a
value of [None].
