Hello, have learned a little more. I need to be a little more informative when I ask a question. Let me start off, the computer I'm using is a gateway433c 256 ram, 10gb hd, has a intel AC97 i810 driver, intel 82810 cgc graphic rev. 03, also installed nvidia NV 11 GeForce mx mx 400 rev. b2 card. Have dedicated HD to VL 5.8 gold, which runs pretty well considering the age of the gateway. Downloaded several live OS, Knoppix 5.1.1 is sometimes hard to boot, I am getting a few failures but sometimes it does load with an error window on the desktop. It reads something like this, system/media/hdc (dev/hdc) named Knoppix can not be unmounted, also below that it states, umount:/cdrom is not in the fstab (and you are not root). It seems to run ok but the error message appears quite frequently. Is there any command to eliminate or fix this?
