When you are satisfied with your IPCop installation, you can remove extra hardware on the IPCop PC: your video monitor and CD drive. You will probably want to leave your floppy disk drive in for backup purposes. If your BIOS permits, you can turn off keyboard detection and remove the keyboard, too.
If you remove the CD drive and/or floppy disk drive, remember to change your BIOS settings so the IPCop PC boots from its hard drive, first.
If you don't remove the floppy disk drive, so that you can use it for backup purposes, remember to change your BIOS settings so the IPCop PC never boots from the floppy drive.
