Chapter 2 BIOS Setup On-Chip IDE Control The chipset contains a PCI IDE interface with support for two IDE channels. Select "Enabled" to activate the first and / or second IDE interface. If you install a primary and / or secondary add-in IDE interface, select "Disabled" to deactivate an interface. If you highlight the literal "Press Enter" next to the "Onchip IDE Control" label and then press the enter key, it will take you a submenu with the following options: On-Chip Primary / Secondary PCI IDE The integrated peripheral controller contains an IDE interface with support for two IDE channels. Select Enabled to activate each channel separately. The Choices: Enabled (default), Disabled. IDE Primary / Secondary Master / Slave PIO The IDE PIO (Programmed Input / Output) fields let you set a PIO mode (0-4) for each of the IDE devices that the onboard IDE interface supports. Modes 0 through 4 provides successively increased performance. In Auto mode, the system automatically determines the best mode for each device. The Choices: Auto (default), Mode0, Mode1, Mode2, Mode3, Mode4. IDE Primary / Secondary Master / Slave UDMA Ultra DMA/100 functionality can be implemented if it is supported by the IDE hard drives in your system. As well, your operating environment requires a DMA driver (Windows 95 OSR2 or a third party IDE bus master driver). If your hard drive and your system software both support Ultra DMA/100, select Auto to enable BIOS support. The Choices: Auto (default), Disabled. 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 mode (most new drives do), select Enabled for automatic detection of the optimal number of block read / write per sector where the drive can support. The Choices: Enabled (default), Disabled. 2-17
