We don't need not stinkin' organization.
NetBSD 1.3, Dell Optiplex GX Pro 200. Built-in (on motherboard) 3c905.
[ this bug filed as 'kern' because it applies to a
machine-independent driver that i'm using on an x86 system.
If that's the wrong classification, refile it! 8-]
The NetBSD 1.3 'ep' driver doesn't work with the built-in 3c905 in
(at least some) Dell systems. I care, because my system happens
to be one in which it doesn't work.
It seems that the 'ep' driver selects an incorrect media type, and
won't allow the user to select any other media types. This makes
it pretty much impossible to install the system using the built-in
The startup messages look like (10-finger copy, with irrelevant
ep1 at pci1 dev 8 function 0: 3Com 3C905 Ethernet
ep1: MAC address ...
ep1: 8KB word-wide FIFO, (undefined) Rx:Tx split, mii default mii
ep1: interrupting at irq 10
The device is detected properly as a 3C905. ifconfig -am shows
the following for ep1 (again 10-finger copy, with irrelevant bits
media: 100baseTX status: active
supported media: 100baseTX
Not only does this not match what's printed at boot (should it?), it
doesn't let me select 10baseT. My network is 10baseT, and the device
is supposed to work with 10baseT. Other systems, e.g. FreeBSD,
do the right thing. (indeed, i don't even have to muck with setting
the media type under freebsd. it either autodetects it, or the
default is 10baseT which works for me.)
It's worth noting that the "(undefined)" message for Rx:Tx split
is probably bogus, as well. It should probably be "unknown." The
value reported by the card is almost certainly _defined_ to have
some meaning (otherwise, why would the card be using it?!), but
that meaning probably isn't known to the NetBSD kernel.
Boot a 1.3 install floppy on my Dell (or probably many other
Dell Optiplex GX Pro systems). Poke around, when you realize
that you can't talk to the network.
"Install FreeBSD." FreeBSD 2.2.5-RELEASE works "out of the box."
