Chapter 4: BIOS Setup
IDE Primary Master/Slave PIO and IDE Secondary Master/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/Slave UDMA and IDE Secondary Master/
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.
SATA Mode
IDE
This option configures the Serial ATA drives as Parallel ATA stor-
age devices.
RAID (Only on NISE 3140M / NISE 3144 series)
This option allows you to create RAID or Intel Matrix Storage
configuration on Serial ATA devices.
AHCI
This option allows the Serial ATA devices to use AHCI (Advanced
Host Controller Interface).
