_EFI_ISA_IO_PROTOCOL Struct Reference
Detailed Description
The EFI_ISA_IO_PROTOCOL provides the basic Memory, I/O, and DMA interfaces used to abstract accesses to ISA controllers. There is one EFI_ISA_IO_PROTOCOL instance for each ISA controller on a ISA bus. A device driver that wishes to manage an ISA controller in a system will have to retrieve the ISA_PCI_IO_PROTOCOL instance associated with the ISA controller.
Field Documentation
The list of I/O , MMIO, DMA, and Interrupt resources associated with the ISA controller abstracted by this instance of the EFI_ISA_IO_PROTOCOL.
A pointer to the in memory copy of the ROM image. The ISA Bus Driver is responsible for allocating memory for the ROM image, and copying the contents of the ROM to memory during ISA Bus initialization.
The size, in bytes, of the ROM image.
