4. BIOS SETUP Onboard Parallel Port [378H/IRQ7] This field sets the address of the onboard parallel port connector. 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. Configuration options: [278H/IRQ 5] [Disabled] [3BCH/IRQ 7] [378H/IRQ 7] Parallel Port Mode [ECP+EPP] The port is both software and hardware compatible with existing parallel ports so that it may be used as a standard printer mode if ECP is not required. ECP mode provides an automatic high burst-bandwidth channel that supports DMA for ECP in both the forward (host to peripheral) and reverse (peripheral to host) direction. This field allows you to set the operation mode of the parallel port. The setting [Normal], allows normalspeed 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 unidirectional data transfer rate; [ECP+EPP] allows normal speed operation in a two-way mode. Configuration options: [Normal] [EPP] [ECP] [ECP+EPP] ECP DMA Select [3] This field allows you to configure the parallel port DMA channel for the selected ECP mode. This selection is available only if you select [ECP] or [ECP+EPP] in Parallel Port Mode above. Configuration options: [1] [3] [Disabled] 4. BIOS SETUP I/O Device Config 48 ASUS MES-VM User's Manual
