All CardBus controllers can work in PCCARD mode. The PAO code does *something* similar to what Ted's code does, but in a bit different manner. I prefer Ted's layout since it's a better separation of functionality than in the PAO code. > > (12/5) PAO includes boot probes for additional devices, and > > (12/29) has better docs, more drivers, and easier setup. > > PAO has driver support for extra devices. Whether the docs are better > and/or the setup is easier is debatable. The boot floppy makes setup easier, and there *is* some documentation that doesn't exist in FreeBSD. Note that some of the PAO manual pages are in-accurate, especially in the pccardc/pccardd area. Those fixes have been ignored by the PAO folks for whatever reasons... > > CL PD6832 (same as added by Ted Faber), TI PCI-1130, and TI PCI-1131 > > chipsets are currently supported.

On certain laptops, you can set the BIOS to have the CardBus controller 'emulate' a PCMCIA controller w/out requiring any OS support. I know of a couple of folks running their CardBus machines under FreeBSD w/out PAO or explicity CardBus emulation code. > > OK, given this information, is it possible for my Toshiba to currently run > > (reliably) any Ethernet cards, and if so, what card is recommended, what's > > the best way to migrate to the necessary OS version, and do I need PAO? > > - FreeBSD-current can't help you unless you can convince your chipset > to run in a PCCARD-compatible mode.

Chances are that *IF* someone can get PAO to work, then with a little bit of work the code can be ported to the new FreeBSD layer that Ted wrote, thus making it work under FreeBSD as well. Nate
