FPC 8084 User’s Manual

On-Chip IDE Channel0/Channel1

The integrated peripheral controller contains an IDE interface with support for two IDE channels. Select “Enabled￿ to activate each channel separately.

The choice: Enabled, Disabled.

IDE Prefetch Mode

The onboard IDE drive interface supports IDE prefetching for faster drive accesses. If a primary and/or secondary add-in IDE interface are installed, set this field to “Disabled￿ if the interface does not support prefetching.

Primary/Secondary Master/Slave PIO

The four PIO (Programmed Input/Output) fields sets 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.

The choice: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.

Primary/Secondary 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 (W indows 98 or a third-party IDE bus master driver). If the hard drive and the system software both support Ultra DMA/33, select Auto to enable BIOS support.

The Choice: Auto, Disabled.

Init Display First

This item is to active whether PCI Slot or on-chip VGA first.

The choice: PCI Slot, Onboard.

IDE HDD Block Mode

Block mode is also called block transfer, multiple commands, or multiple sector read/write. If the 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.

The choice: Enabled, Disabled

Onboard FDD Controller

Select ￿Enabled￿ if the system has a floppy disk controller (FDC) installed on the system board and the FDC will be used. If the and-in FDC are installed or the system has no floppy drive, select ￿Disabled￿ in this field.

The choice: Enabled, Disabled.
