What do the options 'noapic' and 'nolapic' do anyway. I googled and found lots of pages saying try those options if you get lost interrupt errors. But I didn't find anything on what they actually do. Anyone use removable hard drives? I have a couple IDE drives in removable carriers. The main drive is mounted in the system (not in a carrier, this is has the OS), the other three drives swap out in the carriers (one for backups, one from my laptop, and one for movies). The setup worked fine before. I could run the system with just the one drive, or with either of the removable drives in. I upgraded the main drive that is mounted in the system. Now I can't start the system without having one of those removable drives in system. On the old drive, there were two jumper settings: 'master/single' and 'slave'. On the new drive there are four settings: 'master', 'single', 'slave', and 'cable select'. The main drive needs to be the master. When I put the jumper on the master setting, I can't start the system without a removable drive in it. If I set the jumper on single I can't use any of the removable drives. I want to be able to start the system regardless of what is in the carrier,(no drive, or any of th drives). I don't need/want to have a second drive in the system all the time. I don't want to have to open the computer and change jumpers every time I want to use or not use, a removable drive. That was my whole reason for using the carriers in the first place. Any ideas of what I can do to get around this problem.
