This is where I was assuming the issue was. Why is the only question remaining.

Great, here is what it looks like:

  # probe -v
  PCI bridge probe: not found.
  Intel PCIC probe:
    ident(0)=0x83  ident(1)=0x83
    i82365sl B step found, 2 sockets.

Tried this in one of my "itterations" but went back to your suggestion. No joy.

This is why it took me so long to reply. Since I didn't have a lot of time invested in RH6.1, I poked around a bit and have seen mostly praise for RH6.2. So, I jumped in with both feet... and then looked around.

Tried the same configs with native RH6.2 (pcmcia 3.1.8), with the same lack of results. So, I then downloaded the latest pcmcia 3.1.14 bits, config'd, compiled and installed... no joy.

Either card gets recognized, but only whoever is first recognized gets configured.

Could this have something to do with the 0x83 base address being the same on both. One thing I didn't try was forcing the base address. But then, I'm not sure exactly just how to do this.

Thanx again for your pointers.

I neglected to give you the output of dmesg:

  Intel PCIC probe:
    Intel i82365sl B step rev 00 ISA-to-PCMCIA at port 0x3d0 ofs 0x00
      host opts [0]: none

eth0: NE2000 Compatible: io 0x300, irq 10, hw_addr 00:E0:98:02:2D:F5

(I'm also curious why I don't see the infamouse ToPic brige that causes so many fits.)
