Chapter 3 

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. 

 

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
