I use RIS to start Ultrix 2.0 and 3.0 on 4Mb VS2000's. I think I even did it on a 3Mb MVII/GPX. I did cheat; all I used the in-memory kernel for was to chpt and mkfs the file systems and then I ran an rsh to another machine and did a network dump/restore to copy the other machine's file systems onto the local ones. Change the host name in /etc/rc.local, boot, run /usr/lib/sendmail -bz, and presto the new machine is a clone of the original. Takes about 45 minutes to copy an rd53 machine. I did find that I had to delete a bunch of stuff from the in-memory kernel file system when it first booted to have a big enough /tmp to support the network dump/restore. But this way of getting a workstation up is so much easier than a full RIS! It's also the way I get Ultrix 3.0 to run on a single-rd32 machine when RIS thinks the disk is too small. Use RIS to boot up your first machine, then simply use this trick to clone machines from that master. -- -IAN! (Ian! D.
