Just thought I'd share my latest idea with you guys. I did a search on the forums for 'wds' and only found two threads about wd's diagnostics program. So I assume it hasn't already been covered.
But since ubcd uses syslinux as menu system it's relatively easy to make it work via pxe - using a wds server in my case.
Below's the link to a thread where I briefly explained how it's done. Quite simple really. A lot more so than installing a linux from a private ftp appearently.
