When you get Solaris 8, you get a whole bunch of CD's with extra stuff (well 2 or 3) it's in the compian (CD with extra programs). When you invoke the installer, then go through the selection for installation you'll be shown what apps it'll be installing.
Don't try and install it from JUST the CD without starting the installer. I've tried it and couldn't get it to work. Just start the installer then install it. If you want install the rest of the programs to.
Once done type 'which cdrw' at the command line and it'll tell you where it is. Should be off top of my head /usr/sbin or /usr/bin one of those two I'm pretty sure.
Just a hint thoug for when you get it running you'll also need to use the mkisofs command. This is how I would burn a program with this method;
mkisofs -r filename filename.tar | cdrw -i -O
That command would make the following files into ISO format the put the out put to the cdrw program. Option -i burns the CD at the burners speed otherwise it burns at x4 (I think) the -O (not zero) leave the CD open incase you want to add to it later. If you get it going and need a little more help let me know.
Also I use the cdrw program,
A: Because I like it
B: I work with security stuff sometimes, and burning with mkisofs and using cdrw to burn is good. It makes the format of the CD so it can only be read with UNIX/Linux (Think linux). This is good incase someone tried to get the CD and doesn't know what is on it. If it goes into a Windows machine it will think the CD is empty due to the format
