Chapter 4: BIOS Setup
On-Chip Primary PCI IDE and On-Chip Secondary PCI IDE
Enables or disables the primary/secondary IDE. The default is Enabled.
Select Disabled if you want to add a different hard drive controller.
IDE Primary/Secondary Master PIO and IDE Primary/Secondary
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/Secondary Master UDMA and IDE Primary/Second-
ary 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.
On-Chip Serial ATA
Disabled
Disables the onboard SATA.
Auto
The system will detect the existing SATA and IDE drives then auto-
matically set them to the available master/slave mode.
Combined Mode
PATA and SATA are combined. Maximum of 2 IDE drives in each
channel.
Enhanced Mode
Enables both SATA and PATA. Supports maximum of 5 IDE drives.
SATA Only
This option automatically sets the SATA drives to Primary Master
mode. Since the SATA drives are in Master mode, you cannot set
the IDE drive to Master mode.
