Complete newbie to linux.

I have a linux program on a boot floppy which I want to run via knoppix 3.1 (cd boot up version).
I have the following questions:

The original floppy script begins by using the command;
cp /mnt/floppy/etc/* /etc/
There are several different terminal emulations. Which one do I want?
Which partition do I need to make writeable? (eg HDA1,HDA2 etc)
The above command copies the profile to /etc.
How do I enable this profile to overwrite the existing profile?

The next commands are:

mkdir /lincardemu
chmod 777 /lincardemu
gzip -d -c /mnt/floppy/lce.gz > /lincardemu/lce
cp /mnt/floppy/lce/* /lincardemu/
cp /mnt/floppy/loaf.txt /lincardemu/loaf.txt

Will I have sufficient write access to carry these out?

I am using USB serial interface (Pl2303) instead of the normal serial interface. In the config file will I need to change the statements
"xdev = /dev/ttyS0" for it to recognise the serial port coming via the USB socket?


Any help appreciated.
