BIOS Setup
IDE HDD Block Mode
Enabled
The IDE HDD uses the block mode. The system
BIOS will check the hard disk drive for the maxi-
mum 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
The options are Enabled and Disabled.
On-Chip Primary PCI IDE and On-Chip Secondary PCI IDE
These fields allow you to enable or disable the primary and sec-
ondary IDE controller. Select Disabled if you want to add a differ-
ent hard drive controller.
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 com-
plete task by themselves. Your system supports five modes, 0 (de-
fault) 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 ac-
cording to your hard disk drive’s timing.
Mode 0-4
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.
