.Nx*M
|
|
\*V runs on several of the older Macintosh computers.
|
|
About 4 MB of RAM is sufficient to boot a stripped-down custom kernel, and a
|
|
subset of the system can be squeezed onto a 40 MB hard disk with considerable
|
|
creativity and persistence. However, an 80 MB disk should be considered a
|
|
practical minimum, and to do anything more interesting than booting at least
|
|
8 MB of RAM and more disk space is recommended.
|
|
About 180 MB will be necessary to install all of the
|
|
.Nx*M
|
|
\*V binary system distribution
|
|
sets (note that this does not count swap space!). You can drop this
|
|
to 150 MB if you choose not to install
|
|
the binary X11 distribution sets. Much more disk space is
|
|
required to install the source and objects as well; a complete source
|
|
distribution, including X11, consumes nearly 1 GB of storage.
|
|
.Pp
|
|
Please note that to install
|
|
.Nx*M
|
|
\*V using the
|
|
.Ic sysinst
|
|
method, your system must have a minimum of 6 MB of RAM and 60 MB of
|
|
available disk space (i.e. not part of an in-use HFS partition).

If your 68030 system is not listed above, it may be because of a problem

If your 68LC040 system is not listed above, it is due to a problem with

Macintosh IIfx

|

This machine has unusual custom chips for the ADB and serial interfaces

which make support for it difficult. Work is in progress on this, though.

|
|
Quadra 900/950
|

.Pp
|
|
These machines have I/O processor chips for their ADB interfaces similar to

|
those used in the IIfx and thus face similar support problems. Note that you
|
|
can use a serial console on these systems.

This is a separate effort from the \*M port. PowerMacs use hardware that

|
is often fairly different from that of the \*M port. If you are

interested in this, you might want to take a look at the new

|
|
Real Time Clock
|
|
.Pp
|
|
Due to oddities of the Macintosh hardware interrupt priority scheme,
|
|
.Nx*M
|
|
keeps very poor time. Under a high interrupt load (e.g.
|
|
SCSI or serial port activity) , a machine can lose several minutes
|
|
per hour. A consequence of this problem is that attempting to run
|
|
.Ic ntpd
|
|
is generally rather pointless.
|
|
.It
|
|
SCSI difficulties
|
|
.Pp
|
|
The
|
|
.Nx*M
|
|
SCSI drivers are not quite as
|
|
robust as their
|
|
.Tn Mac OS
|
|
counterparts. Symptoms of these
|
|
problems are that some SCSI disks will not work under
|
|
NetBSD that work fine under
|
|
.Tn Mac OS .
|
|
Other problems include
|
|
occasional file system corruption with some types of drives
|
|
and the general unreliability of removable SCSI media.
|
|
Keep in mind that there are no clear patterns with these
|
|
problems, and they do not appear to affect the majority of
|
|
users.
