Re: accessing physical memory mapped to a pci board

I would like to view physical memory that is mapped to a pci board. I
am using a tool called WinIO to try to create a virtual address to
that physical memory. It works for both read and write of some
addresses, like 0x9FFF0. However, the resource the board uses is
address at 0xE8100000 which I cannot pick up with the tool. I have
confirmed that address in windows device manager and in the BAR0 entry
in the table that the PCI board registers with windows. Is there some
protection in Windows that I must circumvent to view that memory?

You're asking a Windows question, not a C question.

comp.os.ms-windows.programmer.win32 *might* be the right place to ask,
but I'm not sure.
