- Integrated Peripherals
On-Chip Primary PCI IDE - This option allows you to enable or disable the primary IDE channel. If disabled, IDE devices connected to the primary IDE channel will not function. If you are using this channel, enable it, if not, disable it to free up an IRQ.
On-Chip Secondary PCI IDE - See On-Chip Primary PCI IDE.
IDE Primary Master PIO - PIO stands for "Programmed Input/Output". This option allows you to select the PIO mode for your primary master IDE device. The higher the PIO mode, the higher the maximum throughput of your IDE device. It is recommended that you set this to "auto" because trying to set it to a speed higher than what your IDE device was designed for can result in data loss.
IDE Primary Slave PIO - See IDE Primary Master PIO.
IDE Secondary Master PIO - See IDE Primary Master PIO.
IDE Secondary Slave PIO - See IDE Primary Master PIO.
IDE Primary Master UDMA - This option allows you to enable or disable UDMA (Ultra Direct Memory Access) support. UDMA is a new protocol for the interface between your computer and the hard drive. It is double the speed of the traditional ATAPI/EIDE protocol. It is recommended that you leave this as auto so the BIOS can automatically detect whether your IDE device/s support UDMA.
IDE Primary Slave UDMA - See IDE Primary Master UDMA.
IDE Secondary Master UDMA - See IDE Primary Master UDMA.
IDE Secondary Slave UDMA - See IDE Primary Master UDMA.
IDE1 Conductor Cable - This is where you can manually selected the transfer speed of your devices connected to IDE1 (e.g. ATA33/66/100/133). You can't set it to anything higher than what your device supports so this is best left set as "auto".
IDE2 Conductor Cable - See IDE1 Conductor Cable
USB Controller - This option enables or disables the USB controller. Enable this if you are using USB devices. If you are not using any USB devices, disabling this option will free up an IRQ.
Init Display First - This option allows you to select the primary graphics card that your system will boot with. If you are using more than one graphics card (e.g. An AGP and a PCI card), select the one you want to use as the primary card. For most of you this will be the AGP card.
