Integrated Peripherals
The "Integrated Peripherals" category allows you to configure the on-board
device controllers.
The followings describe in sequence all the items of this category.
On-Chip Primary/Secondary PCI IDE
The item allows you to enable or disable the built-in IDE hard disk controller.
Select Disabled only if you are using higher performance or specialized
controller card instead of the onboard IDE controller.
IDE Primary/Secondary Master/Slave PIO
Each of these four items sets the mode timing according to the IDE hard disk
drives in your system. 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 is
simpler and more efficient (and faster). PIO mode concerns data transfer rate.
It can be mode 0 to 4. Higher number indicates faster rate.
Primary/Secondary Master/Slave UltraDMA
These items set if the IDE hard disk drive supports UDMA (Ultra 33 synchronous
DMA mode transfer).
USB Controller
This item allows you to enable or disable the on-board USB controller.
USB Keyboard Support
This item allows you to use the USB keyboard in DOS environment.
Init Display First
This item allows the system to initialize the on-board AGP VGA first before
initializing add-on PCI/ISA VGA cards. Select Enabled if you are using Windows
98's multi-display function.
IDE HDD Block Mode
This allows your hard disk controller to use the fast block mode to transfer data
to and from your hard disk drive.
