Hmm..... I'll give it a whirl and see what happens. Just read this in the meantime: http://www.openbsd.org/faq/faq4.html and this: http://www.openbsd.org/faq/faq8.html so I am going to try the /bsd image however my system doesn't have a /etc/boot.conf file so if I wanted to make it permanent do I just simply do this (taken from from boot man page): *EXAMPLES* <http://www.openbsd.org/cgi-bin/man.cgi?query=boot&sektion=8&arch=i386#end> Boot the default kernel: boot> boot Remove the 5 second pause at boot-time permanently, causing*boot* to load the kernel immediately without prompting: # echo "boot" > /etc/boot.conf Regards, Kaya
