Assuming the kernel has drivers for the PCI to PCMCIA bridge in question. Many such bridges are not well supported at the moment, particularly with the in-kernel PCMCIA subsystem rather than the David Hinds' pcmcia-cs package. > I don't know about Linux drivers for Agere/Lucent Orinoco/WaveLAN mini-PCI > radio. I've heard rumours that someone has successfully adapted the orinoco driver to work on the Mini-PCI cards, but I have no details. I wish I could find out because I'd like to merge the changes into the standard orinoco driver. Actually for a Prism II or Agere/Lucent based PCI card (actually the same chipset with somewhat different firmware) it should be quite easy to add support. The orinoco driver already has the initialisation code abstracted out from the driver core and supports both PCMCIA cards and the Apple Airport (AFAIK basically PCI plus some custom Apple power control stuff). It should be quite easy to add a PCI "front-end" to the driver. -- David Gibson | Microsoft: Making the easy things hard david@gibson.dropbear.id.au | and the hard things buggy http://www.ozlabs.org/people/dgibson ** Sent via the linuxppc-embedded mail list.
