Basically, they map the card IRQ/DMA/address ranges onto the (ISA in this case) bus. Once this is done, then the cards should function. Currently, the PCMCIA address range mapping mechanisms (generalized by an ENPIC type enabler) aren't generalized. The upshot of this is that only one of the five chipset types is supported at this time (the Intel -- by far the most popular), and the bridge enabling is done by specific drivers knowing about the address ranges instead of a general "card services" mechanism. The barrier to generalization is that the module would like to handle all of PCMCIA/PCI/EISA/MCA devices as bus attaches, and this code is pretty much not done (the PCI stuff is the closest thing FreeBSD has). I believe someone posted about having hacks for the USR modem to the list at one time. For all other cards, it's pretty much unsupported and not general. For now I would suggest sticking with only supported hardware. Terry Lambert terry@cs.weber.edu --- Any opinions in this posting are my own and not those of my present or previous employers.
