BIOS Setup IDE Prefetch Mode The onboard IDE drive interfaces supports prefetching, for faster drive accesses. Set to Disabled if your primary and/or secondary add-in IDE interface does not support prefetching. Primary/Secondary Master/Slave PIO The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (04) 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. Settings: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4. Primary/Secondary Master/Slave UDMA Ultra DMA/33/66/100 implementation is possible only if your IDE hard drive supports it and the operating environment includes 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/33, Ultra DMA/66 or even Ultra DMA/100, select Auto to enable BIOS support. Settings: Auto, Disable. Init Display First This item specifies which VGA card is your primary graphics adapter. Settings: PCI Slot and AGP. Onboard Lan Device (Optional) The field is available only when LAN is integrated on the board. It determines whether the onboard LAN controller is activated. Setting options: Enabled, 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 read/ writes per sector the drive can support. Settings: Enabled, Disabled. Onboard FDD Controller The item is used to enable or disable the onboard Floppy controller. Select Enabled when you have installed a floppy disk drive and want to use it. Onboard Serial Port 1/2 The items specify the base I/O port address and IRQ for the onboard Serial Port 3-17
