This was tested with a Netgear WG311v2 802.11b/g PCI card. Things that were fixed: - This chip has two memory mapped regions, one at PCIR_BAR(0) and the other at PCIR_BAR(1). This is a little different from the other chips I've seen with two PCI shared memory regions, since they tend to have the second BAR ad PCIR_BAR(2). if_ndis_pci.c tests explicitly for PCIR_BAR(2). This has been changed to simply fill in ndis_res_mem first and ndis_res_altmem second, if a second shared memory range exists. Given that NDIS drivers seem to scan for BARs in ascending order, I think this should be ok. - Fixed the code that tries to process firmware images that have been loaded as .ko files. To save a step, I was setting up the address mapping in ndis_open_file(), but ndis_map_file() flags pre-existing mappings as an error (to avoid duplicate mappings). Changed this so that the mapping is now donw in ndis_map_file() as expected. - Made the typedef for 'driver_entry' explicitly include __stdcall to silence gcc warning in ndis_load_driver(). NOTE: the Texas Instruments ACX111 driver needs firmware. With my card, there were 3 .bin files shipped with the driver. You must either put these files in /compat/ndis or convert them with ndiscvt -f and kldload them so the driver can use them. Without the firmware image, the NIC won't work.
