NetBSD/amiga 1.2 runs on any Amiga that has a 68020 or better CPU with
some form of FPU and MMU, and on DraCos which still have a CIA.
The minimal configuration requires 4M of RAM and about 65M 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) 75M 110M 55M 90M
swap ----- 2M for every M ram -----
local (/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.

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:
Cyberstorm SCSI option, Blizzard IV SCSI, Blizzard 2060 SCSI,
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.
**) Fastlane SCSI is reported to show data errors and hangs at
least when used with multiple devices on the bus. This might
be a problem with any FAS board.
***) 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.
