Chapter 3. The proc File System
• atm/ directory — The files within this directory contain Asynchronous Transfer Mode (ATM) settings

This directory is analogous to the /proc/ide/ directory, but it is for connected SCSI devices.
The primary file in this directory is /proc/scsi/scsi, which contains a list of every recognized SCSI
device. From this listing, the type of device, as well as the model name, vendor, SCSI channel and ID
data is available.
