Chapter 2 BIOS Setup IDE Prefetch Mode The onboard IDE drive interfaces supports IDE prefetching, for faster drive access. If you install a primary and/or secondary add-in IDE interface, set this field to Disabled if the interface does not support prefetching. The Choices: Enabled (default), Disabled. Primary/Secondary Master/Slave PIO The four IDE PIO (Programmed Input/Output) fields lets you set a PIO mode(0-4) for each of the 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 Choices: Auto (default), Mode0, Mode1, Mode2, Mode3, Mode4. Primary/Secondary Master/Slave UDMA Ultra DMA/66 implementation is possible only if your IDE hard drive supports it and the operating environment includes a DMA driver (Windows 98 OSR2 or a third-party IDE bus master driver). If your hard drive and your system software both support Ultra DMA/66, 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 (must new drives do), select Enabled for automatic detection of the optimal number of block read/writes per sector the drive can support. The Choices: Enabled (default), Disabled. Muti-Media setting The multimedia setting submenu is used to configure various multimedia peripherals such as audio and game equipment. If you highlight the literal "Press Enter" next to the "Muti-Media setting" label and then press the enter key, it will take you a submenu with the following options: Onboard Legacy Audio The field controls the onboard legacy audio.
