Do you have the 3/60 working on a serial console?

Setting up another box to netboot the sun3 should be 'relatively' [*]
easy - just need a rarpd & tftpd server, then bootparams or dhcpd
[depending on bootloader] and nfs.

The sun2 needs a nd (network disk) server instead of tftpd - I don't
know if a version exists for Solaris (I'm afraid my sparcs don't run
Solaris :), but if it does the procedure should be pretty similar.
What are you running on your Voyager?

[*] I'm a huge fan of netbooting boxes, so I could be biased. I've
only netbooted sun3 & sparc boxes, so there could well be unexpected
fun with the sun2, but I'm sure there are people on the list who can
chime in if you hit issues :)

The NetBSD netboot http://www.netbsd.org/docs/network/netboot/ docs
cover setting up a server to boot a sun2 or sun3 into NetBSD, but the
server side should be pretty much the same for netbooting SunOS (Just
use the SunOS boot blocks and extract a SunOS disk image into the NFS
root)
