dual boot

[cljlk]

I have Sun solaris 8 in my system Sparc Ultra. I need to install SunOS
system in another disk
and use dual boot to boot up either Solaris 8 or SunOS which depends on the
users.
Thus we need two different operating sytem in one system.
Would any one give me a tip or point out the URL or documents how to install
SunOS and how
to use dual boot to boot up either Solaris or SunOS.

Thanks in addvance.

No problem at all.

You can run only one of them at a time, you know.

Just install the second OS to a separate drive. I run Solaris 9 on c0t0d0
and interchangably Solaris 8 and Solaris 10-beta on c0t5d0.

At the ok prompt:

ok boot disk0 # boots Solaris 9
ok boot disk5 # boots Solaris 8 or 10-beta depending on which drive is
# in that slot of the array.

You're welcome.

You could write a script which uses eeprom to alter the default boot
device and have your user run that before rebooting.

Otherwise simply educate your user which disk contains which OS.

Alternatively, set up the appropriate devaliases in the OBP for your menu
choices. Then, create a custom banner with your menu text.

The following article gives you more information on creating custom
banners and logos:

The installer should give you the opportunity to choose which disk on
which the OS gets installed. If the version of SunOS which you want to
install does not give you that option, then install SunOS to c0t0d0 and
Solaris 8 to c0t2d0.

If you're using the term "SunOS" to mean SunOS 4.x (aka Solaris 1.x)
or earlier, you're SOL: those older versions of the OS don't support
Ultras.
