Item DMA Resources Interrupt Resources Description The DMA Resources menu lets you allocate direct memory access (DMA) channels for an adapter. The menu lists the channel assignments for DMA, which allows I/O devices to transfer data to and from memory. You allocate DMA channels to an adapter by selecting the ISA Resource setting for an available channel. Be sure to read the documentation that comes with your adapter. You might need to make changes to the adapter to accommodate the selections you make for DMA Resources. For example, you might have to move jumpers or switches on the adapter, or make changes to the software that comes with the adapter. The Interrupt Resources menu lets you allocate interrupt requests (IRQs) for an adapter. The menu lists the system IRQs and their functions. You allocate IRQs to an adapter by selecting the ISA Resource setting for an available IRQ. Be sure to read the documentation that comes with your adapter. You might need to make changes to the adapter to accommodate the selections you make for Interrupt Resources. For example, you might have to move jumpers or switches on the adapter, or make changes to the software that comes with the adapter. 92 Using Your Personal Computer
