Integrated Peripherals In this menu, you can change the onboard I/O device, I/O port address and other hardware settings. Figure 3-7. Integrated Peripherals Menu Screen Onboard IDE-1 Controller: The onboard IDE 1 controller can be set as Enabled or Disabled. The integrated peripheral controller contains an IDE interface with support for two IDE channels. If you choose Disabled, it will effect the settings of four items not available. For example, if you disabled the Onboard IDE-1 Controller, you will also disable the Master/Slave Drive PIO Mode and Master/Slave Drive Ultra DMA. Master/Slave Drive PIO Mode: Six options are available: Auto ) Mode 0 ) Mode 1 ) Mode 2 ) Mode 3 ) Mode 4. The five IDE PIO (Programmed Input/Output) items let you set a PIO mode (0-4) for each of the four IDE devices that the onboard IDE interface supports. Modes 0 through 4 provide successively increased performance. In Auto mode (default setting), the system automatically determines the best mode for each device. Master/Slave Drive Ultra DMA: Two options are available: Auto and Disabled. Ultra DMA is a DMA data transfer protocol that utilizes ATA commands and the ATA bus to allow DMA commands to transfer data at a maximum burst rate of 100 MB/sec. Ultra DMA/33 or Ultra DMA/66/100 implementation is possible only if your IDE hard drive supports it and the operating environment includes a DMA driver (Windows® 95 OSR2 / 98 / NT / 2000 or a thirdparty IDE bus master driver). SE6 BIOS Setup 3-15 If your hard drive and your system software both support Ultra DMA, select Auto to enable BIOS support. Auto: Disabled: If you encounter a problem in using Ultra DMA devices, you can try to disable this item. Onboard IDE-2 Controller: Description is same as the Onboard IDE-1 Controller. USB Controller: Two options are available: Enabled and Disabled. This motherboard provides two Universal Serial Bus (USB) ports, thus supporting USB devices. If you don't want to use USB devices, set it to Disabled, then the item USB Keyboard Support & USB Mouse Support will also be disabled.
