I've tried installing versions of Linux on livecds, I've tried Knoppix 3.8.2, Knoppix 3.9, and Slax Kill Bill version 5.0.5. The cds will start to boot Caldera DR DOS, it will find drivers for USB devices and search for hard drives and then freezes. All 3 cds freeze at this point. I wasn't sure if it was something with my computer, a Toshiba Satellite A20, so I tried to install them on another computer, an HP Pavllion a630n, and the process would freeze on that computer too. It did get farther on the other computer, the hard drive would be mounted and it would recongize the USB cable modem and printer. It would then start looking for USB hard drives, it would freeze there. Any ideas on what is going wrong?
