SuSE Firewall on CD and SQUID

Hello Group, just a little question about this nice product. Is it possible to change the squid error pages (html-format) ? I tried to put them on the floppy (in the right subdir, of course), but it seems, that these files won't be copied to the ram-disk. Is the script, responsible for the copy-process, on the CD, or is it on the floppy, so that I can edit it? Thanks in advance, Alexander
