this is my fisrt message and my first experience with IRQ-related problems
with Ethernet card running under Linux.

In particular, my setting is:

Microstar - Medion9648 laptop.
Pentium III 1.2GHz, 384Mb RAM, 30Gb HDD, Internal DVD/CDROM.

PhoenixBIOS Setup Utility - BIOS Version: 1.0C-0016-0713

Dual booting with LILO 2.22:

 - Linux Mandrake 8.2 (kernel 2.4.18-6mdk).
 - Windows XP.

The problem is:

While ethernet card works fine with WinXP, I can't make it run on
Linux. I'm making use of RealTek RTL8139 driver (as a module):

When I try to bring up the eth0 interface I get the following error

% ifconfig eth0 up
SIOCSIFFLAGS: Device or resource busy

If I type ifconfig eth0 I get:

I downloaded (with another PC :-)) and compiled rtl8139-dial.c, and here
is the diagnostic message:

% rtl8139-diag -eam

rtl8139-diag.c:v2.06 3/22/2002 Donald Becker (becker@scyld.com)
Index #1: Found a RealTek RTL8139 adapter at 0x1c00.
This chip has not been assigned a valid IRQ, and will not function.
 This must be fixed in the PCI BIOS setup.  The device driver has no way
 of changing the PCI IRQ settings.
 See  http://www.scyld.com/expert/irq-conflict.html  for more information.
RealTek chip registers at 0x1c00

  No interrupt sources are pending.
 The chip configuration is 0x10 0x8d, MII half-duplex mode.
Decoded EEPROM contents:
   PCI IDs -- Vendor 0x10ec, Device 0x8139.
   PCI Subsystem IDs -- Vendor 0x10ec, Device 0x8139.
   PCI timer settings -- minimum grant 32, maximum latency 64.
  General purpose pins --  direction 0xe1  value 0x12.
  Station Address 00:07:CA:00:45:F2.
  Configuration register 0/1 -- 0x8d / 0xc2.
 EEPROM active region checksum is 09c7.
 The RTL8139 does not use a MII transceiver.
 It does have internal MII-compatible registers:
   Basic mode control register   0x1100.
   Basic mode status register    0x782d.
   Autonegotiation Advertisement 0x01e1.
   Link Partner Ability register 0x41e1.
   Autonegotiation expansion     0x0001.
   Disconnects                   0x0000.
   False carrier sense counter   0x0000.
   NWay test register            0x0004.
   Receive frame error count     0x0000.

Well, I'm a novice in IRQ conflicts, but from messages above it seems IRQ
has not been assigned to ethernet chip. 

What should I do at this point?

If I follow advise to fix PCI IRQ by BIOS setup, and follow instructions
at http://www.scyld.com/expert/irq-conflict.html, I notice that my BIOS
setup utility DOES NOT HAVE option for changing "Installed O/S". In the
Advanced menu there are only the following options:

- PS/2 Mouse
- LCD Panel View Expansion
- Silent Boot
- Frame Buffer Size
- I/O Device Configuration
  - Serial port
  - Infrared port
  - Parallel port
  - Floppy disk controller

but no Installed O/S option...

Can anybody help me at this point?
Alternative solutions/ideas?

Thanks in advance,
