30	 * The start address needs to be a physical address allowing for
31	 * enough room for the console firmware, and the boot loader.
32	 * On most alpha machines, the console fits in no more than
33	 * 2MB, to which we need to add 256KB of boot blocks and the
34	 * initial kernel stack.
35	 * However, some of the last alpha models (*5 D and E series,
36	 * *7, and G series) have much larger console sizes.
37	 *
38	 * For reference, here is a list of systems and their console
39	 * sizes:
40	 *
41	 *	AXPpci33		10e000, 110000
42	 *	EB164			11c000
43	 *	AS400 (Avanti)		11e000
44	 *	2100/A50 (Avanti)	11e500
45	 *	AS1000			12e000
46	 *	AS200, AS255		13a000, 1f2000
47	 *	AS250			148000
48	 *	AS500			14a000
49	 *	AS500/600		14c000
50	 *	Multia			154000, 158000, 166000
51	 *	DS20			156000
52	 *	PC164			180000
53	 *	PWS			1d6000, 1d8000, 1f2000
54	 *	3305 (AS1000A)		1da000
55	 *	164SX			1de000
56	 *	AS1200			1f0000
57	 *	XP1000, AS2100, AS4100	200000
58	 *	ES40, CS20, DS10	200000
59	 *	AS8400			200000
60	 *	ES45			32c000
61	 *	DS25			51c000
62	 *	GS160			5f2000
63	 *
64	 * If you change this value, make sure to update KERNBASE in
65	 * <machine/param.h> as well.
66	 *
67	 * Note that the current setting will not work on a GS160.  If you
68	 * are the lucky owner of such a system and want to run OpenBSD on
69	 * it, please contact <alpha@openbsd.org>
