Forum: PCMCIA Installation and Configuration Issues
Re: Question: Redhat 6.2 pcmcia boot disk (Joao Marques)
Date: 2000, May 22
From: Joao Marques jpdmarques

Hi again!

I installed RH6.1 by CD (to make a copy of RH6.2 in my hard disk with wget) but now the problem is different.

(pcmcia-cs-3.1.15 drivers)

#dmesg 

Linux PCMCIA Card Services 3.1.15
  kernel build: 2.2.12-20 #1 Mon Sep 27 10:25:54 EDT 1999
  options:  [pci] [apm]
PCI routing table version 1.0 at 0xfdf70
Intel PCIC probe:
  TI 1211 rev 00 PCI-to-CardBus at slot 00:0a, mem 0x68000000
    host opts [0]: [ring] [pci + serial irq] [pci irq 9] [lat 32/176] [bus
32/34]
    ISA irqs (scanned) = 3 PCI status changes
cs: IO port probe 0x1000-0x17ff: excluding 0x1000-0x10ff 0x1400-0x14ff
cs: IO port probe 0x0100-0x04ff: excluding 0x220-0x22f 0x378-0x37f
0x388-0x38f 0x4d0-0x4d7
cs: IO port probe 0x0a00-0x0aff: clean.
cs: memory probe 0xa0000000-0xa0ffffff: clean.

By default it detects a ne2000 compatible card:

eth0: NE2000 Compatible: io 0x300, irq 3, hw_addr 00:A0:0C:40:99:4C

But,

#/etc/rc.d/init.d/network start Bringing up interface lo [ OK ] Bringing up interface eth0 

eth0: Reentering the interrupt handler! isr=0x0 imr=0x0.
eth0: Reentering the interrupt handler! isr=0x0 imr=0x0.
eth0: Reentering the interrupt handler! isr=0x0 imr=0x0.
...

It almost works, but that message is always appearing. (it does the dhcp; ping also works).

So the only explanation is that this card is not ne2000 100% compatible, which a search to the file /etc/pcmcia/config confirmed: 

(...)
card "WiseCom WC-PC400 Fast Ethernet"
  manfid 0x8a01, 0xc1ab
  bind "smc91c92_cs"

This is my card (so i thinked; now i don't know :) ): 

#cardctl ident
Socket 0:
  product info: "PCMCIA", "10/100 Ethernet Card", "", ""
  manfid: 0x8a01, 0xc1ab
  function: 6 (network)

After replacing this entry by the one that conflits with this one, the card was successfull detected

#dmesg

(...) smc91c92_cs: using 8-bit IO window. eth0: smc91c??? rev 13: io 0x100, irq 3, hw_addr FF:FF:FF:FF:FF:FF

but badly configured. So this card probably doesn't use a smc91c92/94/95/96/100/100-FD/110 chipset. Is there any way to see if this card in fact uses a different chipset or this is result of a bug / conflit / error ?
