To boot from the CD, you need to make sure the CD is set as the first
device to try booting from. All of them are different, but there must
be some way
to get into the BIOS setup screen before the system boots. Most common is
"press del for setup", but there are those that need F2, \, esc and
other keys
to go to the setup screen. In there, there should be a boot order
selection.
Once you have it booted up, you need to open a terminal window. There
should
be a "sea shell" icon on the bottom left. Click it and you should get a
character
cell terminal window.

Now, type the following :
mkdir /mnt/floppy
mount /dev/fd0 /mnt/floppy
ls /mnt/floppy

(at this point, you should get a directory listing of the floppy)

cd /usr/local/emc
./generic.run -ini /mnt/floppy/<file name>

This should run EMC and tell it to read the ini file from the floppy.
Now, the explanation.

The mkdir command may be optional, but it seems on these the mount
points are not set
up by default, so the mkdir command creates a "mount point" in the file
structure where
the floppy file system can be mounted to. (This is nothing like how it
works on Windows.)

mount connects the floppy device (/dev/fd0) to the file system at the
mount point /mnt/floppy
It should automatically identify the floppy's file system, but if not,
it may be necessary to
load a kernel module with this command: modprobe fat

ls lists the contents of the floppy file system

cd changes the current directory location to what is specified

./generic.run runs the script generic.run from the current directory.
the "./" syntax is
a quirky linux thing due to the strict command syntax used by the bash
command
interpreter. The dot means the current directory, and the slash
isolates the dot so
it doesn't mean a dot as part of the file name. The rest of the line
tells generic.run
that you are specifying what ini file to use. the <file name> is
replaced by the
file name on the floppy. Note that all this syntax is case dependent,
and the file
name must be typed with the same case as it shows on the ls command.
