[Gerrit Bruchhäuser]

Hello Sean,

thank you very much - you realy helped me a lot. I wrote to the top 
because this question had been already posted many times. See for 
instances: http://www.leto.net/mail/linuxasm/2001/msg00538.html

If this is ok for you then I would like to copy+paste your answer to all 
these postings I crossed.

Many thanks and cheers!
