---------------

This kernel compiles almost cleanly:

* I had to compile obio.c with -DSUN4 [which I pr'ed]

* I had to comment out lines from ioconf.c [This is what broke it I guess]

/sys/arch/sparc/compile/DOUBLESIX:neil@doublesix>diff ioconf.c.orig ioconf.c  
15c15
< extern struct cfdriver oclockcd;
---
> /* extern struct cfdriver oclockcd; */
65c65
<       {&oclockcd,      0, NORM, loc+ 16,      0, pv+ 8, 0},
---
> /*    {&oclockcd,      0, NORM, loc+ 16,      0, pv+ 8, 0}, */


However if I didn't do that I got this link error:

loading netbsd
ioconf.o: Undefined symbol `_oclockcd' referenced from data segment
*** Error code 1

Can someone tell me what I've not understood? The kernel doesn't configure 
things like esp and a pile of other things and then panics with boot device 
not known.

Thanks,
Neil.
