IRQ This function lets you assign an interrupt for serial ports 1 and 2. The options for serial ports 1 are IRQ 4 and 11. The options for serial port 2 are IRQ 3 and 10. The Base Address and IRQ parameters for each port are configurable only if the port is enabled. 2.5.2 Parallel Port This parameter allows you to enable or disable the parallel port. Base Address This function lets you set a logical base address for the parallel port. The options are: • 3BCh • 378h • 278h The default setting is 378h. IRQ This function lets you assign an interrupt for the parallel port. The options are IRQ 5 and 7. The Base Address and IRQ parameters are configurable only if Parallel Port is enabled. If you install an add-on card that has a parallel port whose address conflicts with the onboard parallel port, a warning appears on the screen. Check the parallel port address of the add-on card and change the address to one that does not conflict. Chapter 2 - BIOS Utility 2-17
