PCI Slot IDE 2nd Channel
This item allows you designate an IDE controller board inserted into one of the PCI slots as
your secondary IDE controller.
Enabled External IDE controller designated as the secondary controller
Disabled No IDE controller occupying a PCI slot.
On-Chip Primary PCI IDE
As stated above, your system includes two built-in IDE controllers, both of which operate on
the PCI bus. This setup item allows you either to enable or disable the primary controller.
You might choose to disable the controller if you were to add a higher performance or
specialized controller.
Enabled Primary HDD controller used -- Default
Disabled Primary HDD controller not used.
On-Chip Secondary PCI IDE
As above for the Primary controller, this setup item allows either to enable or disable the
secondary controller. You might choose to disable the controller if you were to add a higher
performance or specialized controller.
Enabled Primary HDD controller used
Disabled Primary HDD controller not used.
IDE PIO
IDE hard drive controllers can support up to two separate hard drives. These drives have a
master/slave relationship which is determined by the cabling configuration used to attach
them to the controller. Your system supports two IDE controllers--a primary and a
secondary--so you have the ability to install up to four separate hard disks.
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. This simpler faster and more efficient.
Your system supports five modes, numbered from 0 (default) to 4, which primarily differ in
timing. When Auto is selected, the BIOS will select the best available mode. This is true
for the next four setup items:
IDE Primary Master PIO
IDE Primary Slave PIO
