7: Software Updates
DC 900-1333Q 187
disk (previous versions had to be explicitly commanded to perform this service by set-
ting “PRESERVE_PARTS=yes”). Another enhancement starting with that version is
that now when the Freeway is booted from the CDROM, it determines the IP address
which is used by the Freeway when booted normally (from its own disk), and sets an
alias to that IP address. So if, for example, your Freeway ordinarily uses IP address
192.168.100.100, then when you boot it from the CDROM it will have two addresses:
192.168.135.1 (the standard address for a CDROM-booted Freeway) and
192.168.100.100 -- and you can telnet to it using either of those addresses. These two
enhancements simplify upgrading your Freeway.
Below are the procedures: first the new procedure, then the previous one -- use the sec-
tion corresponding to your CDROM's Freeway version. And as always, if you have any
questions or problems upgrading your Freeway to any Freeway software version, don't
hesitate to contact Protogate directly, at (US) 858-451-0865 or [e-mail].
7.2.1 Freeway CDROMs “X-B” (3.1-3) or later
First backup anything on your Freeway that you want to preserve (most Freeways do not
have anything which must be preserved, but if you are developing code on the Freeway
you may have some files on its disk, or if you have altered or created additional config-
uration files you may wish to save those). Then insert the CDROM into the Freeway's
CDROM drive and boot the Freeway. It will boot from the CDROM, and once it has
completed booting you should telnet to it (using either its usual IP address or
192.168.135.1), login as root/setup, type “6” to enter the command shell, then type
these commands, exactly as shown:
cd /etc
. /etc/rc.buildfwy
The rc.buildfwy command will warn you that it's going to overwrite things on the disk,
but you don't need to type anything more; just give it 10 minutes or so to finish, and
then you can remove the CDROM and reboot your Freeway again, and it will be using
the new software.
