That's because the /dev directory does not contain 'files' as such but simply a look up table for the all-important device nodes. Major / minor nodes are like PO boxes, each one is uniquely assigned, and set in concrete. to a specific type of driver (scsi, cd, video, etc). The nodes are used to communicate with a given driver, the name 'hdc', or 'pink_elephants', has no meaning to the driver, simply that 'pink_elephants' is an accepted alias for a node. Thus there was no problem symlinking node 11/1 to 'hdc', it simply meant that the label 'hdc' was henceforth a scsi cd driver name. (unusual but not an issue). What happened however is that by doing so you removed any nodal reference to 22 0, the device node that the ide cdrom driver expects. Thus, your DVD 'dissappeared' because there was no means of accessing 22 0, even though the driver was sitting there patiently waiting. -- http://linux.nf -- [EMAIL PROTECTED] _________________________________________________________ Do You Yahoo!?
