Hello,
I had success with my old laptop and FreeBSD 5.x now. I compiled a new
set of installation floppies with the pccard daemon and using
device pcic
device card
instead of
device cbb
device pccard
device cardbus
in the kernel. The old pccard bus driver uses a polling mode if he is
not able to map an IRQ. It seems like that the new driver won't do this.
Is there a specific reason why this was not implemented? Is this still
possible or isn't it worth because too less hardware demands it anymore?
Thanks in advance
Björn
