AMI BIOS Setup
#:
If enabled in BIOS Setup and supported by the hard disk, AMI BIOS
enables LBA mode and translates the physical parameters of the
hard disk drive. If the hard disk is formatted, AMIBIOS enables LBA
mode. If a hard disk that supports LBA mode and has a capacity
greater than 528 MB was formatted with LBA mode disabled,
AMIBIOS does not enable LBA mode even if LBA mode is enabled
in AMIBIOS Setup. Choose On to enable support for IDE drives with
capacities greater than 528 MB.
Block Mode - Block mode boosts IDE drive performance by
increasing the amount of data transferred. Only 512 bytes of data
can be transferred per interrupt if block mode is not used. Block
mode allows transfers of up to 64 KB per interrupt.
If the IDE drive supports block mode and it is enabled in BIOS
Setup, AMIBIOS enables multi-sector transfers. AMIBIOS sets the
number of sectors to be transferred per interrupt to the value
returned by the identify drive command.
PIO Mode - IDE PIO mode programs timing cycles between the IDE
drive and the programmable IDE controller. As the PIO mode
increases, the cycle time decreases. IDE PIO modes 3 through 7
are the advanced PIO modes. The IDE controller on the CPU card
must support the IORDY signal before an advanced IDE PIO mode
can be implemented.
Select Auto to allow AMIBIOS to automatically choose the PIO
mode that the IDE drive being configured uses. If you select 0-5
you must be absolutely certain that you are selecting the PIO mode
supported by the IDE drive being configured.
32Bit Mode - Hard disk drives connected to the computer via the
ISA bus transfer data 16 bits at a time. An IDE drive on the PCI or
VL-Bus local bus can use a 32-bit data path. If enabled in AMI BIOS
Setup, AMI BIOS enables 32-bit data transfers. If the host does not
support 32-bit transfer, this feature should be disabled.
#" Boot Sector Virus Protection
When this item is enabled, AMIBIOS issues a warning when any
program (or virus) issues a Disk Format command or attempts to write
to the boot sector of the hard disk drive. The settings are Enabled or
Disabled (default). If enabled, the following message appears when a
write is attempted to the boot sector. You may have to type <N>
several times to prevent the boot sector write.
