Hi, just a short heads-up because I did not find teh Ultra 25 on the list of "supported" systems. I wanted to give it a try and can confirm that it boots from CD and gets into the "Select a language" screen but the keyboard is not working.
System: Sun Ultra 25, 1 GB RAM, 250 GB SATA, XVR-300, kbd/mouse connected to the USB ports I will try a serial install once I find the adaptor. Cheers Iggi.
