// hello, i had a heck of time with pcmcia when i upgraded slink to potato. after serveral attempts on different lapboxes, i was successful. (i said "no" to shutting down pcmcia card services during the potato install. after everything was installed, i re-ran "pppconfig" and was surprised to find that the modem "moved" from /dev/ttyS0 to /dev/ttyS1, or something like that. as long as it works, i don't care where it chooses to be.) anyway, what happens when you boot? do you get two high beeps for the pcmcia, a hi-low beep sequence, or no beeps? i re-ran potato's "pppconfig" and let it probe the ttyS's when i had either the 2 high beeps but no dial-out or the hi-low beep sequence (and obviously, no dial-out). i wouldn't even have an anecdotal recommendation if there are no beeps. (but, if i were to guess, i'd try a trusted older kernel, which for me is 2.0.36--yes, i'm running potato on it, for now.) hopefully, some others will chime in on this one. hth. bentley taylor. //
