CD-ROM saga (a funny story)

After much delay, for what reason, I don't know, I finally dropped into
Quay Computers
and bought a CD-ROM.  Not a flash one, just an old 24x speed which had a 30 day warranty.  A decent deal for NZ$95.   I planned to install it that night, but something else came up.
When I got home later that day, I found that the FreeBSD box had rebooted.  At first I thought 'power cut'.  Then I saw that NT1 was still running.  And both used the same UPS.  So it wasn't a power problem.  There was no reason for the reboot that I could see.  So I decided to ignore it and press on with other things.   Namely, the CD-ROM.
I switched off the firewall and installed the CD-ROM.  When I switched on the machine, the screen filled with Ys.  Lots of them.  Continuously filling the screen.  Line by line.   I couldn't figure it out.  So I disconnected the drive from the IDE controller.  The machine then ran OK.  But I couldn't connect from NT1 through the firewall to the Internet.  And my DNS was stuffed.  What was going on here!
I figured something really serious had gone wrong.  Anything from someone hacking into my system and changing something to a power surge blowing some code on the hard drive.  I spent 4 hours trying to get it running again.  Finally, I sent a message to the
FreeBSD Questions mailing list
and headed off to bed.  Very annoyed!
10 July 1998 - Inspiration
The next day I figured it out during a lull at work (actually, I was staring out the window at the harbour wondering why I wasn't out there riding my bike).  Master.  Slave.  Can't have two masters.   DOH.
That night, I got it right.  I swapped the little plug thing at the back of the CD-ROM and converted it from a master to a slave.  You see, the IDE controller was already looking after the hard drive.  Which is normally the master.  And the machine booted.
The next step was mounting the drive.  Which was a journey in own right.
Mounting the CD-ROM Drive
I received one suggestion about making sure the network cards where both working.   They were.  So I gave up on the firewall problem and decided to install the CD-ROM.
The
FreeBSD
site was down and I couldn't search for instructions on how to mount the drive.  It's not like Windows where the thing is just there.  You actually have to issue commands in order to see the drive.
I rang up Jay, who had a guest, but helped anyway.  We found out what device the drive was mapped to.  By using the command dmesg, you can see the boot time messages.  We found wcd0.  He told me to try:
