A short description of the screen items follows:

and Play-aware (e.g. Windows 95).
Resources Controlled By: The Award Plug and Play BIOS can automatically configure all the
boot and Plug and Play compatible device. If you select Auto, all the interrupt (IRQ) and DMA
assignment fields disappear, as the BIOS automatically assigns them.
Reset Configuration Data: If enable this option, the BIOS will clear and reset the ESCD after
hardware reset.
IRQ#/DMA# assigned to: These items will be shown only when “Resources Controlled By”

option is set to “Legacy ISA”, the BIOS will never assign the specified IRQ/DMA resource to
