IsaBus DXE_DRIVER 240612B5-A063-11d4-9A3A-0090273FC14D 1.0 Component description file for IsaBus module. Discovers all the ISA Controllers and their resources by using the ISA PnP Protocol, produces an instance of the ISA I/O Protocol for every ISA Controller found, loads and initializes all ISA Device Drivers, matches ISA Device Drivers with their respective ISA Controllers in a deterministic manner, and informs a ISA Device Driver when it is to start managing an ISA Controller.

If it is unset, these interfaces will return EFI_UNSUPPORTED. When it is disabled, it is will save code size if a platform does not have ISA device with ISA memory. PcdIsaBusSupportDma gEfiGenericPlatformTokenSpaceGuid TRUE This feature flag is used to enable the implementation for interface _EFI_ISA_IO_PROTOCOL.AllocateBuffer, _EFI_ISA_IO_PROTOCOL.FreeBuffer, _EFI_ISA_IO_PROTOCOL.Map and _EFI_ISA_IO_PROTOCOL.UnMap. If it is unset, these interfaces will return EFI_UNSUPPORTED. It is useful to save code size if a platform does not have ISA device which did DMA transfer. PcdIsaBusOnlySupportSlaveDma gEfiGenericPlatformTokenSpaceGuid FALSE This feature flag is used to enable the implementation for interface _EFI_ISA_IO_PROTOCOL.Map and _EFI_ISA_IO_PROTOCOL.UnMap to only support Slave DMA transfers. In addition, unsetting this feature flag also make AllocateBuffer() and FreeBuffer() to return EFI_UNSUPPORTED. It is useful to save code size if a platform have only ISA device to do slave DMA R/W transfer. This flag is only effective when PcdIsaBusSupportDma is set to TRUE. If PcdIsaBusSupportDma is set to FALSE, Map() and UnMap() will simply return EFI_UNSUPPORTED. Please check description for PcdIsaBusSupportDma for details.
