Video BIOS Shadow (Enabled) This field allows you to change the video BIOS location from ROM to RAM. Relocating to RAM enhances system performance, as information access is faster than the ROM. C8000-CBFFF to DC000-DFFFF (Disabled) These fields are used for shadowing other expansion card ROMs. If you install other expansion cards with ROMs on them, you will need to know which addresses the ROMs use to shadow them specifically. Shadowing a ROM reduces the memory available between 640KB and 1024KB by the amount used for this purpose. BIOS (BIOS Features) 36 ASUS P/I-P550 User's Manual IV. Onboard Serial Port 2 (2F8H/IRQ3) Settings are 3F8H/IRQ4, 2F8H/IRQ3 (default), 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for the onboard serial connector. Onboard Parallel Port (378H/IRQ7) This field sets the address of the onboard parallel port connector. You can select either: 3BCH / IRQ 7, 378H / IRQ 7 (default), 278H / IRQ 5, Disabled. If you install an I/O card with a parallel port, ensure that there is no conflict in the address assignments. The PC can support up to three parallel ports as long as there are no conflicts for each port. 38 ASUS P/I-P550 User's Manual IV. BIOS SOFTWARE Parallel Port Mode (ECP+EPP) This field allows you to set the operation mode of the parallel port. The setting Normal, allows normal-speed operation but in one direction only; EPP allows bidirectional parallel port operation at maximum speed; ECP allows the parallel port to operate in bidirectional mode and at a speed faster than the maximum data transfer rate; ECP+EPP (default) allows normal speed operation in a two-way mode. ECP DMA Select (3) This selection is available only if you select ECP or ECP+EPP in the Parallel Port Mode. Select either DMA Channel 1, 3 (default), or Disable. UART2 Use Infrared (Disabled) When enabled, this field activates the onboard infrared feature and sets the second serial UART to support the infrared module connector on the motherboard.
