Hi All
I've written a working bootloader, and part of its task is
to scan the PCI bus and allocate memory. There are two bits
per device, indicating whther or not th device needs I/O
and/or Memory access. There are straightforward to set up.
However, there is a this bit, to decide whether or not
Bus-Master access is required: how do I determine whether a
certain slot requires this access, so that I know whether to
set/clear this bit?
Thanks
Bruce
