Due to lack of documentation - not at the moment. Even the BSD folks haven't managed to get that bit going. Pulling the card registers for the device in Windows PIO4 would be most useful. > Linux throughput of 'dd bs=100MD' writing to FAT16 (Dell 3GHz P4 x86 32bit, > kernel 2.6.23): > > 3.1MB/sec for Linux PCMCIA (legacy delkin_cb.c ) > 1.8MB/sec for Linux CardBus 32 (libata pata_ninja32.c) Yes. I've not had time to go back and do more investigating.
