Integrated peripherals (Cont.)

IDE prefetch mode: If you IDE interface supports IDE prefetching this will allow for faster drive access. Enabled is faster, only disable if not supported.

Init display first: If you have only 1 graphics card in your system this can be ignored. If you have multiple graphics cards in your system, select either PCI or AGP depending on which one you want to use. This is useful for those of you who have motherboards with graphics cards soldered into the motherboard.

USB controller: If you use USB devices then you'll need to leave this enabled. Otherwise disable it, you'll free up an IRQ in the process too.

IDE HDD Block Mode: This setting allows for multi-sector transfers, enabled is faster.

IDE 32-bit transfer mode: Select enabled to use 32-bit I/O accesses with your hard drive. This is faster, although it has been known to cause data corruption in Windows NT.

Onboard FDD controller: If you use FDD's (Floppy Disk Drives) then you'll need to have this enabled.

Onboard serial port 1: Use this to set/disable/change the address for Serial port 1. You can manually select an address for it, e.g. 3E8/IRQ4, disable it altogether or set it to Auto. I'd recommend leaving it set to Auto.

Onboard serial port 2: Use this to set/disable/change the address for Serial port 2. You can manually select an address for it, e.g. 3E8/IRQ4, disable it altogether or set it to Auto. I'd recommend leaving it set to Auto.

Onboard parallel port: Sets the address for the parallel port to use. Leave it at the default setting unless you need to change it to fix a resource conflict.

Parallel port mode: Use this to select the operation mode for the Parallel Port. You may need to check your motherboard manual to find this out. ECP mode being the best. Depending on your choice one of the following submenus may become available.

·       ECP mode use DMA: Use this to select the DMA channel for ECP or ECP+EPP to use.

Parallel port EPP type: When using EPP mode you can choose between EPP 1.7 or EPP 1.9
