- When _L_i_n_u_x boots, it displays a handful of information. Those
- information may be useful to diagnose some problems. _L_i_n_u_x generally
- print information on the hardware it probes. Fortunately all this info
- is stored in a buffer, retrieved by askrunlevel and saved in the file
- /var/adm/boot.log.

- Beware that with the advent of modular kernel and on demand loading of
- device drivers, the information in the log is not complete. The /proc
- file-system is a useful complement to grab more information about the
- hardware of your computer. The following files are of special
- interest.
-
- ╖ /proc/cpuinfo
-
- ╖ /proc/interrupts
-
- ╖ /proc/ioports
