>Description:
Configured a kernel just for a DS5000/133 to test diskless booting. Compilation
running on a DS3100 running NetBSD 1.2_Beta.

******This looks like a show-stopper for the 1.2 release for DS5000/1xx users.

Compilation failed at line 1594 in pmax/machdep.c with a diagnostic telling
that kn03_tc3_imask is undefined.

Looking at the code (see extracts below), I notice that this variable is
only defined for a DS5000_240, but used in code for a DS5000_100.

#ifdef DS5000_240
u_long	kn03_tc3_imask;
extern u_long latched_cycle_cnt;
#endif

----text cutted----

#ifdef DS5000_100
----text cutted-----
void
kmin_enable_intr(slotno, handler, sc, on)

----more text cutted--------
#if defined(DEBUG) || defined(DIAGNOSTIC)
	printf("3MIN: imask %x, %sabling slot %d, sc %x addr 0x%x\n",
	       kn03_tc3_imask, (on? "en" : "dis"), slotno, sc, handler);
#endif


>How-To-Repeat:
Define a kernel configuration file that is targeted at a DS5000/1xx, but
not at a DS5000/2xx.
>Fix:
	Either remove the diagnostic printout around line 1594 or make the
variable declaration for kn03_tc3_imask available for all cpus that need it.
