	$NetBSD: hardware,v 1.26 1998/10/29 20:57:03 is Exp $	

NetBSD/amiga _VER runs on any Amiga that has a 68020 or better CPU with
some form of MMU, and on 68060 DraCos.

For 68020 and 68030 systems, a FPU is recommended but not required for the
system utilities.
68LC040, 68040V and 68LC060 systems don't work correctly at the moment.

The minimal configuration requires 4M of RAM and about 75M of disk
space.  To install the entire system requires much more disk space,
and to run X or compile the system, more RAM is recommended.  (4M of
RAM will actually allow you to compile, however it won't be speedy. X
really isn't usable on a 4M system.)

Here is a table of recommended HD partition sizes for a full install:
	partition:	advise,	with X,	needed,	with X
	root (/)	20M	20M	15M	15M
	user (/usr)	95M	125M	75M 	105M
	swap		----- 2M for every M ram -----
	local (/usr/local)	up to you


As you may note the recommended size of /usr is 20M greater than
needed. This is to leave room for a kernel source and compile tree as
you will probably want to compile your own kernel. (GENERIC is large
and bulky to accommodate all people).

If you only have 4M of fast memory, you should make your swap partition
larger, as your system will be doing much more swapping.

	Real-time clocks:
		A2000, A3000, A4000 builtin (r/w),
		DraCo builtin (r/o).

If its not on the above lists, there is no support for it in this
release. Especially (but this is an incomplete list), there is no
driver for:

	Blizzard III SCSI option, Cyberstorm Mk III SCSI option,
	Ferret SCSI, Oktagon SCSI.

Known problems with some hardware:

	*) the Emplant SCSI adapter has been reported by a party to
	hang after doing part of the installation without problems.

	***) SCSI scanner support is machine independent, so it should
	work, but hasn't been tested yet on most Amiga configurations.
	There are reports that the Mustek and HP Scanjet hang if
	accessed from the A3000. This might apply to other
	33C93-Adapters, too.

	****) Our floppy driver doesn't notice when mounted floppies are 
	write-protected at the moment. Your floppy will stay
	unchanged, but you might not notice that you didn't write
	anything due to the buffer cache. Also note that HD floppy
	drives only get detected as such if a HD floppy is inserted at
	boot time.
