changing BIOS settings in XP

Does anyone know how to change the BIOS settings in XP? I used to know how to do this in previous OS versions, but can not figure it out in XP.

 

I need to change the settings for the parallel port to the following:

enabled

Mode = ECP

Port address = 378h

IRQ = 7

DMA = 3

 

From what I can see in the Device Manager, the mode and port address are set as needed, but I need to change the IRQ and DMA.

 

I have spent over an hour with Dell Support, but with no luck in reaching anyone who can answer anything but the most basic questions. The tech support documentation is of no help.

 

Thanks anyone
