PRIMARY MASTER/SLAVE PIO:
The four IDE PIO fields allow you to set a PIO mode (0-4) for each of the
four IDE devices that the onboard IDE interface supports. Modes 0 through
4 provide successively increased performance. In Auto mode, the system
automatically determines the best mode for each device.
PRIMARY MASTER/SLAVE UDMA:
Ultra DMA/33 implementation is possible only if your IDE hard drive
supports it and the operating environment includes a DMA driver (Windows
95 OSR2 or a third-party IDE bus master driver). If you hard drive and your
system software both support Ultra DMA/33, select Auto to enable BIOS
support.
INIT DISPLAY FIRST:
This item allows you to decide to active whether PCI Slot or on-chip VGA
first. The choices are PCI Slot and Onboard.
IDE HDD BLOCK MODE:
Block mode is also called block transfer, multiple commands, or multiple
sector read/write. If your IDE hard drive supports block mode (most new
drives do), select Enabled for automatic detection of the optimal number of
block read/writes per sector the drive can support.
ONBOARD FDC CONTROLLER:
Select Enabled if the system has a floppy disk controller (FDC) installed on
the system board and you wish to use it. If you install and-in FDC or the
system has no floppy drive, select Disabled.
