My configuration, which I just set up recently is:

Intel Celeron 400 Mghz
PCI/AGP/ISA motherboard
Matrox something or other video card
3com 3c905 NIC (thank you for 3.3 :-)
64 Meg of ram

I also have in the box the 2 devices I would like to get working:

3com 3c509 NIC
US Robotics PCI Faxmodem (which is type 3cp5610)

Now, there is supposedly support for the 3c509, but no matter what
I adjust the configuration file to, it is never recognized.  Even taking
out all the other NIC drivers, nothing.  I have adjusted the 3c509 to
300/IRQ15.  I have removed all NIC drivers except xl0 and ep0.
Any ideas?

The 3com Fax-Modem is actually a modem on a serial card, it is a 16550 (A?B?)
chip, which is used to talk to the modem.  Support Class 2.0 fax modem
communications which is good.  The PCIConf information is:

none1@pci0:15:0: class=0x070002 card=0x00ad12b9 chip=0x100812b9
	rev=0x01 hdr=0x00 

Which according to the PCI information I can find, is a stupid serial
adapter.  I have the driver set to the correct IRQ, but am not sure about the
base address.  If I remember my PCI information correctly, the port information
is at offset 114 (short offset, 228 byte offset).  I have set the driver to
0xa000 which the value there.  Unfortunately, since I stopped working for the
company I was doing kernel work at, I no longer have access to the PCI doc
I had.

Any clues?

I would like to use this machine as a firewall between my home LAN and the
outside world.  While I can do this with one NIC and assign 2 IP addresses
to that NIC (assuming I can do that), I would prefer to use 2 NICS.  The modem
is there to keep me from having yet another wall wart :-)

Thanks for any information you might provide.
