I have a PCMCIA radioethernet adapter that has an unusual programming interface: instead of having an I/O ports range [for control] and one memory area to send/receive data it has two memory areas, one for controlling and one for data itself. As far as I know standard FreeBSD pccard manager doesn't support such cards directly (I have been playing w/ it for a while :-)) but I see that in recent PAO3 releases/snapshots there are some significant changes in the pccard manager code itself and [probably] there are some handles to map both memory areas simultaneously. Although this code seems to be for 'CardBus support' w/o mention my case directly. Could anyone tell me whether I could work w/ this new interface and how I should do this (i.e what function calls should be performed in the driver to make this work). Also I need a general (pccard) driver writing info. Any help in this direction will be thankfully appreciated Yours sincerely, Alexey Morozov To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
