i'm not sure where to begin  :)

i have a 5000/240 with serial console.  i had to change pmax/dev/findcons.c
like this to make it work:

Index: findcons.c
===================================================================
RCS file: /cvsroot/src/sys/arch/pmax/dev/findcons.c,v

  	int kbd_slot;
  {
  #if NSCC > 0
+ #if NPM > 0
  	if (kbd_slot == 3) {
  		cd.cn_dev =  makedev(SCCDEV, SCCKBD_PORT);
  		lk_divert(sccGetc, makedev(SCCDEV, SCCKBD_PORT));
  		cd.cn_getc = LKgetc;
  		return 1;
  	}
+ #endif /* NPM */
  #endif /* NSCC */
  	return 0;
  }

i have no idea if this is correct but it built.. 

i also can't build a 240-only kernel (i haven't tried others) yet.  once i
worked out to use options DEC_3MAXPLUS i started getting these sorts of
errors:

/sys/arch/pmax/pmax/dec_3maxplus.c:105: pmax/pmax/dec_3max_subr.h: No such file or directory
/sys/arch/pmax/pmax/dec_3max_subr.c:43: pmax/pmax/dec_3max_subr.h: No such file or directory

so i took those lines out (seems that header has gone the way of the dodo).

now i get this:

/sys/arch/pmax/pmax/dec_3maxplus.c: In function `dec_3maxplus_os_init':
/sys/arch/pmax/pmax/dec_3maxplus.c:160: `mips_hardware_intr' undeclared (first use this function)
/sys/arch/pmax/pmax/dec_3maxplus.c:160: (Each undeclared identifier is reported only once
/sys/arch/pmax/pmax/dec_3maxplus.c:160: for each function it appears in.)
cc1: warnings being treated as errors
/sys/arch/pmax/pmax/dec_3maxplus.c: In function `dec_3maxplus_errintr':
/sys/arch/pmax/pmax/dec_3maxplus.c:494: warning: implicit declaration of function `dec_mtasic_err'

and

/sys/arch/pmax/pmax/dec_3max_subr.c:53: warning: function declaration isn't a prototype


mips_hardware_intr is used in a bunch of pmax/dec_XXX.c files and dec_mtasic_err
is defined in dec_3max_subr.c but no header files.


and that's where i am at the moment.
