Hi,
your issue-discription is a little bit poor. I assume thats the reason why nobody answers.
What do you mean with "evendvd diskdoes"??
Which version do you tried?
If you mean, that the installation-cd boots, but don't find the cd-media, then the cd-rom isn't supported (ask your server-vendor for debian lenny support). Use simply an external CD-ROM connected via usb and boot from there.
If you came further with the installation, where is the problem?
