I would love to do that, but I need a struct pci_dev before I can use
pci_write_config_byte() and friends. To find a pci_dev (with
pci_find_device() I think) I need a vendor and device id. My problem is
that I don't have these. My device is a CR16MCS9 (see google) which has
been bolted onto the PCI/ISA bridge. This device reports no vendor or
device id to the system, well.. maybe it does, but then I can't find it.
I can therefore not see how I can get a pci_dev pointer and thought that
my only solution was to write directly to the pci registers. Is there
another way around this problem ?
Thanks,
