Hello.
I will have to review my notes and locate the links I used to obtain Ubuntu 8.04 and Debian v40r3... If those prove to be dead links, I can always push the ISO to the KCS depot server and provide you with a link. I will get back with you after work today.
By the way, what is the specific HP/Compaq hardware platform and generation on which you are trying to install UT (version?) I would like to replicate your configuration here so I can follow along while we work this.
Thanks,
Matthew.
