IDE HDD Block Mode

Enabled
The IDE HDD uses the block mode. The system BIOS will check the
hard disk drive for the maximum block size the system can transfer.
The block size will depend on the type of hard disk drive.

Disabled
The IDE HDD uses the standard mode.

IDE DMA Transfer Access

This field, when Enabled, will enhance the IDE DMA transfer of an
IDE hard disk drive.

On-Chip Primary PCI IDE

Enables or disables the primary IDE. The default is Enabled. Select
Disabled if you want to add a different hard drive controller.

IDE Primary Master PIO and IDE Primary Slave PIO

PIO means Programmed Input/Output. Rather than have the BIOS issue
a series of commands to effect a transfer to or from the disk drive, PIO
allows the BIOS to tell the controller what it wants and then let the
controller and the CPU perform the complete task by themselves. Your
system supports five modes, 0 (default) to 4, which primarily differ in
timing. When Auto is selected, the BIOS will select the best available
mode after checking your drive.

Auto
The BIOS will automatically set the system according to your hard
disk drive’s timing.

Mode 0-4
You can select a mode that matches your hard disk drive’s tim-
ing. Caution: Do not use the wrong setting or you will have drive
errors.

IDE Primary Master UDMA and IDE Primary Slave UDMA

These fields allow you to set the Ultra DMA in use. When Auto is
selected, the BIOS will select the best available option after checking
your hard drive or CD-ROM.

Auto
The BIOS will automatically detect the settings for you.

Disabled
The BIOS will not detect these categories.
