It looks like pata_pcmcia is always PIO mode 0: /** * pcmcia_init_one - attach a PCMCIA interface * @pdev: pcmcia device * * Register a PCMCIA IDE interface. Such interfaces are PIO 0 and * shared IRQ. */ I assume that with old IDE this would use ide_cs.c, but I'm drawing a blank on what modes that supports.. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from [EMAIL PROTECTED] Home Page: http://www.roberthancock.com/ _______________________________________________ Linux PCMCIA reimplementation list http://lists.infradead.org/mailman/listinfo/linux-pcmcia
