hardware revision 1.3 
1NetBSD/sparc RELEASE runs on the following classes of machines:
2	- sun4c (e.g. the SS1, SS1+, SS2, IPC, ELC, IPX, and SLC)
3	- sun4 (e.g. the 4/100, 4/200, and 4/300.   note that support
4		for the 4/400 processor is incomplete)
5
6NetBSD/sparc RELEASE does *not* run on these machines (yet):
7	- sun-4/400 (lacking support for the I/O cache, and has
8			ethernet problems)
9	- sun4m (e.g. sparc classic, 4, 5, 10, and 20)
10	- sun4d (e.g. sparc center 2000)
11
12Work on porting NetBSD/sparc to the sun4m platform is currently in 
13progress, but was not ready in time for the 1.1 release.
14
15The minimal configuration requires 4M of RAM and ~60M of disk space.
16To install the entire system requires much more disk space, and to run
17X or compile the system, more RAM is recommended.  (NetBSD with 4M of
18RAM feels like Solaris with 4M of RAM.) Note that until you have
19around 16M of RAM, getting more RAM is more important than getting a
20faster CPU.)

22Supported devices include:
23	sun4c sbus video: 
24		cgsix, cgthree, and bwtwo frame buffers
25	sun4 video (not thoroughly tested?): 
26		P4 on-board bwtwo, and VME cgtwo card
27	serial ports: 
28		ttya and ttyb (can be used as console if needed)
29	ethernet: 
30		on-board AMD Lance ethernet ("le0"), 
31		Sbus AMD Lance ethernet cards, 
32		on-board Intel 82586 ethernet (ie0 on 4/100's and 4/200's), 
33		VME Intel 82586 ethernet cards
34	SCSI: 
35		on-board "esp" SCSI controller (sun4c's, and the 4/300),
36		sbus "esp" SCSI controller, 
37		Sun "SUN-3"/"si" VME SCSI controller (polled mode only, slow),
38		Sun "SCSI Weird"/"sw" on-board controller (4/110 only, polled)
39	VME disks:
40		Xylogics 7053 VME/SMD disk controller ("xd"),
41		Xylogics 450/451 VME disk controller ("xy")
42		[note: VME/IPI disks are not supported]
43	sun floppy disk drive on sun4c's
44	sun keyboard and mouse
45	sun4c audio
46
47
48Hardware the we do NOT currently support, but get many questions
49about:
50	sun4m, including multiprocessor machines
51	interrupt driven SCSI driver for sun-4/100's and sun-4/200's
52
53The next release will hopefully run on many more machines.  In
54particular, some Sun4m support will be there.
