I have a Sun Ultra% box with a big internal disk plus a external disk array.

currently I have Solaris 8 loaded.

From time to time, I need to evaluate various different software/patches etc running on different versions of Solaris.

I was told I could install different versions of Solaris on the same disk but just don't know how.

Can someone help me?  

(detailed procedures are needed)

Many thanks in advance

you can distinguish several kernels by specifying the device environment variable in the boot eeprom (see man eeprom: boot-* commands). Some of these commands are similar to those in the boot monitor itself.
AFAIK there is no way to store sevaral pathes and make a choice on boot.

You can install more than one copy of Solaris on a system with multiple disk drives and you can boot whichever you like by specfying the disk to the EPROM boot command. I don't know if you could coerce the installation program into placing more than one copy on a single disk. Of course you could always move an installation to other other slices, but I suspect that the EPROM boot command isn't prepared to deal with that.

Since you effectively only have two disks, the internal drive and the array, you could simply backup the current installation to the array and restore a different configuration from a previous backup onto the array. Since that would be disk-to-disk it would be relatively quick.
