SMC EZ PC card


Hi,

I have an old 486 - toshiba techra, a square grey box of significant size. I installed debian onto it no problem and seems to be running fine. I want to get the ethernet card (and, very wishfully thinking, the wifi card). They are both pcmcia cards, the ethernet card being and SMC ez pca card 10/100 model SMC8040TX.

I have googled a bit and not been able to find anything. I am sure the card works as I have tried it in another computer. Also when I installed the lights lit up, when I did a previous install I managed to install debian from a netinst image - it went and grabbed everything from the net with no problems. Now that I have the distro installed the card is refusing to work.

ifconfig -a shows only the loop back device, lspcmcia shows nothing and dmesg also shows nothing on insertion.

Can anyone give me a pointer about how to get this setup

Thanks
David

Confirm if pcmcia modules driver is available with command "lsmod", if it isn't exist, try:
sudo modprobe pcmcia

I think you might need more than just that one module..
http://kernel.org/pub/linux/utils/ke...ia/pcmcia.html


aptitude install pcmciautils sysfsutils
modprobe pcmcia_core pcmcia firmware_class

Hi,

Thanks for your replies. Pcmciautils was already installed, I had to install sysfsutils. Modprobing the suggested drivers and a subsequent lsmod confirms that they were installed. Unfortunately the card still isn't showing any life.

After a reboot and modprobing again, dmesg and igconfig -a shows nothing different than previously.

does anyone have any more suggestions that I could try? Since this card installed on this computer with this os on install I have no reason to believe that it won't work

I just wonder if you are running into an issue because the system hardware is so old.. Have you been able to get ANY pcpmcia cards to work in that laptop ?


did you look at the rest of the info in the link I provided in my previous post ?
Quote:
Known problems
applying / removing socket power

These are covered at an extra page:

* cs: pcmcia_socket0: unable to apply power
* cs: pcmcia_socket0: *** DANGER *** unable to remove socket power

Unable to suspend Thinkpad T.22

This Thinkpad does not like us placing the Yenta bridge into PCI D3 state.
cs: unable to map memory

Try issuing


pcmcia-socket-startup


CardBus (sometimes also PCMCIA) cards not found

On several, especially new systems the Yenta bridge is not on the root PCI bridge, but behind a PCI-to-PCI bridge. On some x86 or x86_64 systems, these bridges aren't correctly set up by the BIOS, which may cause CardBus and even PCMCIA devices not to show up in lspci or in pccardctl ident correctly. If you suspect that this may be the cause, issue this command:


lspci -v | grep subordinate


Its result may be like this:


Bus: primary=00, secondary=02, subordinate=04, sec-latency=64
Bus: primary=02, secondary=03, subordinate=06, sec-latency=176
Bus: primary=02, secondary=07, subordinate=0a, sec-latency=176


Let's decode the first line: bus 0 (primary) is bridged to busses 2 (secondary) to 4 (subordinate) by a bridge. The second and the third line state that bus 2 is bridged to busses 3-6, and 7-10. However, the CPU (which itself is connected to bus 0 through the root bridge) needs to be able to access all these busses. If you try to walk the tree to bus 7, for example, you see that the CPU can't get there, as bus 0 is only bridged to busses 2 to 4.

If this is the case, or you find a message stating "try pci=assign-busses" in the dmesg log, append the following to the kernel boot line:


pci=assign-busses


Additional information, and a proposed workaround can be found at bug #5557.
