How to create an OpenBSD 3.4 ISO:

1. Download the requisite files from ftp://ftp.openbsd.org. (I would suggest ports.tar.gz, src.tar.gz, sys.tar.gz and the entire i386 folder.)
   

2. On your old OBSD machine (since you all have one), cd to the root of the new CD
   

3. Use mkhybrid to make an ISO: mkhybrid -b i386/floppy34.fs -c boot.catalog -l -J -L -r -o obsd34.iso . (That final period is necessary! Isn’t it always?)
