"The Linux Professional Institute has plans for three levels
of certification, with each level consisting of two exams that you
must pass. Last month, I looked at exam 101, the first test in
the first level (the upper two levels are still in development).
This month, I'll focus on exam 102 (full name known by VUE is
117-102). The following list of fifty key points to know is
excerpted from the upcoming book, LPI General Linux 1 Exam Cram
(Exam 102), to be published in March 2001 by The Coriolis
"1. The /proc/interrupts file shows what interrupts are
currently in use on your system."
"2. Linux supports standard serial, parallel, and joystick ports
in use today. Serial UART types 8250, 16450, 16550, and 16550A are
supported and the /dev directory contains a file for each
port/device supported. The setserial command can be used to list
and alter configuration."
"3. The dmesg command can show what devices (such as lp) that
Linux found during boot."
