-
- 1) IRQ 9 is IRQ 2 for the interrupt controller cascade.
-
- 2) Where the device is found is dependant not on where the device
- actually is, but on the kernel configuration.
-
- 3) If you have a video card on IRQ 2/IRQ 9 (ie: vertical retrace
- interrupt), like some VGA's, you will need to either physucally
- cit the trace (some cards have a little "o" shaped trace that
- will let you do this and reconnect it with solder later), or you
- will need to either change your ethernet interrupt as part of
- a kernel rebuild or use one of the "tape on the card edge" type
- hacks to prevent IRQ 2 from contacting the card connector.
-
- 4) The Base and DMA addresses are also tied into the kernel config.
-
- 5) The cards can be at the wrong interrupt and still be recognized,
- since the probe routines check memory locations rather than
- making sure an interupt from the card occurs.
-
- 6) If you have the card on IRQ 3 or IRQ 4, you should know that
- most "disable com port" jumpers on motherboards with built in
- com ports *don't* disable the interrupt latch, and so still
- interfere with other cards on that interrupt (DTK and Intel
- motherboards are particularly bad at this).
-
- 7) As long as the default route specified to your "route" command
- refers either to a packet forwarding host, like a cisco box, or
- the host you are going to FTP to, you're OK with the route.
-
- 8) The default netmask on an ifconfig seems to be 255.255.255.255,
- which is obviously bogus. You need to specify a "netmask <value>"
- on the end of your ifconfig for this to work correctly. For a
- class A net, value is 255.0.0.0, for a B it's 255.255.0.0, and for
- a class C it's 255.255.255.0. The network number in your post
- is 192.1.1.2, so it's a class C.
-
- 9) The "startart" is from a debug message in the driver you are
- using. You can get rid of this when you recompile the kernel;
- it wil, however, slow down FTP until then (you need the bin and src
- distributions, in that order, to rebuild the kernel -- if you
- have a small drive, you can download the tar.Z (prepared, I believe,
- by Amacio?) containing only the kernel sources. You still need the
- bin, however).
-
- 10) Make sure our second computer isn't the problem by talking to a
- system other than the 386BSD box you are trying to get set up.
- There's nothing you can do to a 386BSD box that will make it talk
- to another computer if the other computer has a bad ethernet adapter.
-
-
- Hope this helps.
