Re: pcmcia support with no ISA bus?

Hi Warner,

I currently have an IBM S31 that could not function with oldcard.
It seems to be resource conflicts.  How should I find out
the available IRQ's and IOMEM's on -current?

Also, I have attached the necessary info in this url:
http://people.freebsd.org/~keichii/ibm_s31_info.tgz

The problem is that no matter what IRQ i assign the cards,
wi0 never attached in the CF slot.  And putting any card in
pcic0 (the normal pcmcia form factor) panics or freezes the system.
It looks like a IRQ storm, but I am not sure.

Will your patch work with my system?

It also contains the dumpcis that you requested a long time
ago for the CF form factor wlan card.

Thanks,
  Michael
