After a pin broke in my built-in network socket I was forced to re-examine the
pcmcia card network option.

To recap, previous attempts got the following result

Sep 19 01:29:29 philipashmore kernel: pccard: PCMCIA card inserted into slot 1
Sep 19 01:29:29 philipashmore kernel: cs: memory probe 0xf4000000-0xfbffffff:
excluding 0xf4000000-0xf8ffffff
Sep 19 01:29:29 philipashmore kernel: pcmcia: registering new device pcmcia1.0
Sep 19 01:29:29 philipashmore kernel: eth%d: pcnet_reset_8390() did not
complete.
Sep 19 01:29:29 philipashmore kernel: pcnet_cs: unable to read hardware net
address for io base 0xe300

I noticed that after inserting the following into /etc/pcmcia/config.opts

    exclude port 0xd000-0xefff

(the indent is for readability) I got
Sep 19 02:09:55 philipashmore kernel: pccard: PCMCIA card inserted into slot 1
Sep 19 02:09:55 philipashmore kernel: cs: memory probe 0xf4000000-0xfbffffff:
excluding 0xf4000000-0xf8ffffff
Sep 19 02:09:55 philipashmore kernel: pcmcia: registering new device pcmcia1.0
Sep 19 02:09:55 philipashmore kernel: eth%d: pcnet_reset_8390() did not
complete.
Sep 19 02:09:55 philipashmore kernel: pcnet_cs: unable to read hardware net
address for io base 0xf300

Note the change in the last line - I probably missed it loads of times.

I finally got it to work by using

   exclude port 0xd000-0xffff

Sep 19 02:17:10 philipashmore kernel: pccard: PCMCIA card inserted into slot 1
Sep 19 02:17:10 philipashmore kernel: cs: memory probe 0xf4000000-0xfbffffff:
excluding 0xf4000000-0xf8ffffff
Sep 19 02:17:10 philipashmore kernel: pcmcia: registering new device pcmcia1.0
Sep 19 02:17:11 philipashmore kernel: eth1: NE2000 (DL10019 rev 05): io 0x300,
irq 3, hw_addr 00:e0:98:70:27:d8
Sep 19 02:17:11 philipashmore kernel: pcmcia: registering new device pcmcia1.1
Sep 19 02:17:11 philipashmore kernel: 1.1: ttyS1 at I/O 0x2f8 (irq = 3) is a
16550A

To re-iterate, inserting the following into /etc/pcmcia/config.opts

    exclude port 0xd000-0xffff

Fixes the problem - I'm using it now to file this message.
