Proc - IDE directory
The subdirectory /proc/ide contains information about all IDE devices of which the kernel is aware. There is one subdirectory for each IDE controller, the file drivers and a link for each IDE device, pointing to the device directory in the controller specific subtree.
The file drivers contains general information about the drivers used for the IDE devices:
cat /proc/ide/drivers ide-cdrom version 4.53 ide-disk version 1.08
More detailed information can be found in the controller specific subdirectories. These are named ide0, ide1 and so on. Each of these directories contains the files shown in this table.
