PCI IDE Present on Slot 1

If this option is set to

Enabled,

PCI IDE adapter cards that require IRQ14 are supported on slot 1 (P16) only. Switch1-

8 must be set ON to enable IRQ14. PCI IDE adapter cards that support configuration registers with proper IDE class
code information are automatically handled. For PCI IDE adapter cards that do not set the IDE class code, this option
must be set to ON. This will program the base registers to 1F0h - 1F7h and 3F6 - 3F7h. These devices will then work
with the main BIOS IDE support. The settings are

Enabled

or

Disabled.

The Optimal and Fail-Safe default settings are

Disabled.

IDE 32 Bit Transfer

32-bit data transfer on the IDE data port can be enabled through this option. If disabled, 16-bit data transfer is used by
the BIOS. 32-bit data transfers can only be enabled if IDE prefetch mode is also enabled. The settings are

Enabled

or

Disabled.

The Optimal and Fail-Safe default settings are

Disabled.

IDE Block Mode

This option enables multiple sector reads and writes for IDE drives. The settings are

Enabled

or

Disabled.

The

Optimal and Power-On defaults are

Disabled.

PCI IDE Host Timing

The settings are

Slow

or

Fast.

The

Fast

setting saves one clock on the lead-off cycle of the onboard PCI IDE. The

Optimal and Fail-Safe default settings are

Slow.
