BIOS Setup
OnChip SATA
This field is used to enable or disable the onboard SATA.
IDE DMA Transfer Access
This field, when Enabled, will enhance the IDE DMA transfer of an
IDE hard disk drive.
OnChip IDE Channel0 and OnChip IDE Channel1
These fields allow you to enable or disable the primary and second-
ary IDE controller. The default is Enabled. Select Disabled if you want
to add a different hard drive controller.
IDE Prefetch Mode
This allows data and addresses to be stored in the internal buffer of
the chip, thus reducing access time. Enable this field to achieve better
performance.
Primary Master/Slave PIO and 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
Mode 0-4
68
The BIOS will automatically set the system according
to your hard disk drive's timing.
You can select a mode that matches your hard disk
drive's timing. Caution: Do not use the wrong setting
or you will have drive errors.
