Very Computer

I have installed Linux kernel 2.0.0 with Slackware 3.1 on a Gateway
 PPro 200. I have a BusLogic BT-948 card and a 3C590 Ethernet card.
 Drivers for both are configured into my Linux kernel. Upon booting,
  The SCSI card is recognized, and the Ethernet card is detected.
 However, ifconfig does not recognize the ethernet connection.

 If I disconnect the BT-948 card, ifconfig recognizes the Ethernet card.

 The IRQ for the BusLogic and the 3C590 cards = 10. These values are
 set at the factory and cannot be modified with the respective setup
 programs.

 Is this IRQ conflict the source of my problems ? Is there a workaround
 available ?

                    Thanks

If you have two devices using the same irq, then yes, this is your problem.

The work around, download the 3c590 utility disk image from www.3com.com
and create a utility diskette for your network card.  One should have
came with it, but it's on the web.  Boot to dos, a dos boot disk will
be fine, no need to create a dos partition on your harddisk.  Insert
the utility disk and run the 3c590cfg.exe program.  During that process
it will allow you to turn off PnP and manually set an irq & i/o address.

Do so manually, not choosing irq10 that is being used by the buslogic card.
Reboot system, linux should autodetect the new irq/port for the 3com card.

Problem solved.

The BT-948 is a PCI card (unless I've misunderstood something).  This
means that its IRQ should be configured at system start-up by the
system BIOS through the PCI bus.

I assume the 3c590 is an ISA card, and I suspect that you need to use
your system BIOS setup to inform the BIOS that IRQ 10 is in use by an
ISA card; the BIOS will then assign a different IRQ to the BT-948.

It works better you see, when it goes to 11.

Having just gone through this process, things are much simpler. Remove
the 3c590 card and reboot, passing 'linux single' to the LILO
prompt. Halt the system & reinsert the 3c590. When you reboot they
will have different PCI interrupts. If they don't, read the section in
the Buslogic manual about non-conforming motherboards & * to Gateway.

You can't set the IRQ for the 3c590 - you must be thinking of the 3c509.
