[realtek] Device or resource busy

FYI,
Linux 2.2.14-5.0
PnP OS not enabled in Bios (Award Modular Bios v6.00PG)

I ran rtl8139-diag with the '-p' and '-t' options because it would not work
otherwise.
So, I first used the i/o address found in windows, where the card works:
    ./rtl8139-diag -t 2 -p 1400 -e >& diag-1.log
This returned the following which I piped into a file:

 http://www.scyld.com/diag/index.html
Assuming a SMC1211TX EZCard 10/100 (RealTek RTL8139) adapter at 0x1400.
Decoded EEPROM contents:
   PCI IDs -- Vendor 0xffff, Device 0xffff.
   PCI Subsystem IDs -- Vendor 0xffff, Device 0xffff.
   PCI timer settings -- minimum grant 255, maximum latency 255.
  General purpose pins --  direction 0xff  value 0xff.
  Station Address FF:FF:FF:FF:FF:FF.
  Configuration register 0/1 -- 0xff / 0xff.
 EEPROM active region checksum is 17e8.

Then I looked at /proc/pci:
------
  Bus  0, device  13, function  0:
    Ethernet controller: Unknown vendor Unknown device (rev 16).
      Vendor id=1. Device id=1211.
      Medium devsel.  Fast back-to-back capable.  IRQ 11.  Master Capable.
Latency=32.  Min Gnt=32.Max Lat=64.
      I/O at 0xdc00 [0xdc01].
      Non-prefetchable 32 bit memory at 0xde008000 [0xde008000].
------
and used the i/o address of the card found there:
    ./rtl8139-diag -p 0xdc00 -t 2 -e >& diag-3.log

This returned the following which I piped into a file:

  Station Address 00:E0:29:88:BC:C7.

and adding -ee options gives:

So, now I am lost.  The card appears to be found on a pci scan but linux and the
rtl8139 driver cannot access the card.  What should be in the EEPROM?
Also, I noticed that IRQ=11 is assigned to both the ethernet card and a scsi card -
I believe IRQ sharing is now handled by OS's (Windows and Linux).

Thanks for any help, TK
