Description Choices
Resources Controlled by
The Award Plug and Play BIOS can automatically configure
all the boot and Plug and Play - compatible devices. If you
select Auto, all the interrupt request (IRQ) and DMA
assignment fields disappear, as the BIOS automatically
assigns them.
If you use a manual setup option, you can set to Legacy ISA,
the IRQ/DMA which you do not wish to be assigned
automatically in the next IRQ/DMA Resources setup.
This will prevent the IRQ/DMA number from being
assigned automatically by BIOS.
