3-4 Integrated Peripherals

This section provides information on setting peripheral devices. By choosing the Integrated Peripherals option from the CMOS Setup Utility menu (Figure 3-1), the screen below displays the manufacturer's default values for the motherboard.

Figure 3-5 Integrated Peripherals Screen

OnChip IDE Device:

Press [Enter] to enter the sub-menu, which contains the following items for advanced control:

1.On-Chip Primary/Secondary PCI IDE:

You can set this to disable the On-Chip IDE controller if you are going to add a higher performance IDE board

2.IDE Primary/Secondary Master/Slave PIO:

The four IDE PIO (programmed Input/Output) fields let you set a PIO mode (0-4) for each IDE device that the internal PCI IDE interface supports. Modes 0 through 4 provide successively increased performance. In Auto mode, the system automatically determines the best mode for each device.

3.IDE Primary/Secondary Master/Slave UDMA:

Ultra DMA implementation is possible only if your IDE device supports it and your operating environment contains a DMA driver. If both your hard drive and software support Ultra DMA, select [Auto] to enable BIOS support.

4.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, select Enabled to auto-detect the optimal number of block read/writes per sector the drive can
