Well, you don't have to rely on those new-fangled, "visually-oriented" tools
like vi, you can go old-school. :-) Edit your /etc/zipl.conf from the
console using sed(1) or ed(1). Neither of these need any character
positioning functionality from the terminal, so they work fine from the
console.
To use sed, try something like this (assuming there is no "dasd=" option in
your "parameters" line, but there is a parameters line):
# sed '/parameters[ \t]*=/s/"/"dasd=100-104 /' /etc/zipl.conf > /tmp/zipl.conf
# cat /tmp/zipl.conf # So you can see your change to make sure it worked.
# mv /tmp/zipl.conf /etc/zipl.conf
Or with ed (all but the first line are input to ed):
# ed /etc/zipl.conf
/parameters[ \t]*=
s/"/"dasd=100-104/p
w
q
You might have to tweak the regular expressions to match what is in your
zipl.conf, but the above works on my SLES9 box. Good luck!
