Well, my point is sn driver can't know that.  Since behavior was
changed as of OT 1.1.1, whether sn driver conforms to the old way or
the new way, it will probably make someone unhappy (some of us
including me are still reluctant to use OT to begin with).

Good.  It's clear that the problem is not related to bootp now...

Your bootp server can see the packet, yet you get "Tx - timeout"s?
That's weird.  It sounds as if the SONIC chip can read the buffer but
cannot write.

Even if I did, it wouldn't work.  First, your card has to be
identified as Apple Ethernet NB TP.  Second, even if it were
identified as such, I don't know the address (offset) of the on-board
RAM.

Anyway, first thing first, please download Slots from the following
URL, run it on your system, write down the output by hand (it can be
quite lengthy, though), and send it to me or the list.

ftp://ftp.apple.com/devworld/Tool_Chest/Devices_-_Hardware/NuBus_Slot_Manager/Slots.sit.hqx

(Yeah, I know it's also somewhere on puma, but from Russia
ftp.apple.com might be faster...)

We need the output for the particular slot number where your Ethernet
card is installed.  But we don't need the output for your video, etc.
