This is a problem I've had for a while but haven't properly resolved.
I've got a 3Com589D Ethernet card and a XJack Sportster Modem card
in a IBM TP560, and am using Linux 2.0.29 with PCMCIA card services
version 2.9.7. In brief my problem is that with both cards installed
in the machine together neither actually works successfully. If I
eject one or other card before booting then the remaining card operates
correctly. Nevertheless, 'cardmgr' does recognise both cards in
the machine simultaneously and gives no indication of any conflict.
When I first tried both cards together (4+ months ago) I noticed some
postings reporting similar concerns in this newsgroup. Unfortunately
I didn't act on them at the time and I can't find any record of the
advice. I remember though that many answers suggested turning of
Plug-n-Play on the cards (except one respondent who said this was
not completely necessary).
Could someone suggest what I should try to fix this? I can get more
detailed diagnostics if needed.
