Usually less than 2MB/s means you don't have DMA enabled, which usually means you are using the wrong ide driver or have a bad configuration somewhere. You can check the settings in /proc/ide/hda/settings or whatever your HD is. As for installing knoppix that way, I have no idea. knoppix is a tolerable live cd but I would hate to have it as my normal use system. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
