Play-compatible devices. If you select Auto, all interrupt request (IRQ), DMA

the following types in accordance with the type of devices using the interrupt:
1. Legacy ISA Devices compliant with the original PC AT bus specification,

2. PCI/ISA PnP Devices compliant with the Plug and Play standard, whether
designed for PCI or ISA bus architecture.
The default value is “PCI/ISA PnP”.
