That I do not know, but I can tell you that the 68K kvm and sys trees <br>
are not present.<br>

Ah yes I remember that, how far have you gotten?<br>
<br>
I myself am simply trying to recompile zs_async.c with some quick <br>
changes to keep it from changing the parity and bitness on serial <br>
consoles at boot time. We have a couple of big Suns running at LSSM, <br>
whose consoles are handled through a terminal server network, and the <br>
parity/bits switching is a pain in the ass.<br>
<br>
But I don't know if the driver is the same between sun3 and sun4/4c/4m.<br>
