The problem will even be more extensive as the size of the PCMCIA memory
window is platform specific. Generally you should have enough window space
as early Flash cards were flash chip arrays mapped into the local
processor space (up to 64MB). But as these cards become more scarce there
isn't much of a need to make the window large anymore. You could try to
take the base address which should just be the physical address (system
bus address) and perform your own virtualalloc/copy. You also have to
consider that you are operating in the device.exe process, you could be
running out of virtual memory or mapping resources.
