Can Solaris 2.3 & SunOS4.1.3 Be Run on One Sparc Machine?

I mean to run two OS on same machine?

If so, how?

Yes, it is possible to run both SunOS 4.1.3 and Solaris2.3
on the same Sparcstation. In fact, I'm currently doing it.

I have a pair of drives in the sparc10, and i've turned off
the autoboot options in the startup eeprom.

To boot I use 'boot disk1' or just 'boot' and I get the
different OS's. When installing I just told Solaris2.3
to ignore the first drive.

I've also heard it can be done on a single drive by using
different slices as the root partition, and sharing the swap
area.

I currently run SunOS 4.1.3C and Solaris 2.X on the same sparc 10.
The technique I use requires two disks. Install the two OS's on
separate disks. At boot time, at the prom prompt enter:

boot diskn<return>

where "n" is the number of the scsi disk you want to boot from.

Good luck, Steven Barkdull

I currently run SunOS 4.1.3 and Solaris 2.3 on a SPARCstatio 10 with
only one disk. The machine has an internal 1.05 GByte disk drive. I
was using it as a SunOS 4.1.3 machine with partition h (0.5 GByte)
used as a local /home2 (I mount /home from a server). I used this
partition for a complete Solaris 2.3 installation. The swap partition
is used by both OSses.

To mount SunOS I have to type "boot disk", to boot Solaris I have to
type "boot disk0:h". As I use Solaris most times, I changed the load
device using "setenv boot-device disk0:h" to make the h partition the
default.

Yes, set up two disks, one with 2.3 and one with 4.1.3. Use the 'boot'
command at the console to select which OS to boot. You can even mount
the 4.1.3 disk from 2.3. I'm not sure if you can go the other way.

You *can* mount 2.3 partitions from 4.1.3. I use three disks, one to boot
4.1.3, the second to boot 5.3, and the third to hold /home and /u partitions
mountable from either OS.

Do you have an estimate of what sizes the OS specific disks need to be,
I have 4.1.3 on a 600Mb drive, and will have a 200Mb and a 1Gb drive as
well, I'd obviously prefer to put Solaris on the 200Mb and have the 1Gb
mountable from either, but I'm not sure if that is practical.

I can help with that. You won't get a full OS with on 200Mb disk.
It leaves off at least the man pages, if not other things.
I tried it...
