Battery check

Basic checks, hardware support, benchmark

List loaded modules + list if how to custom tests

Network + ifconfig, ping

Video/Webcam ls /dev/ | grep video + mplayer + xawtv

Sound lsmod | grep ^snd + speakertest + alsamixer

Mic arecord,aplay

Graphic startx /usr/bin/window manager

Benchmark - phoronix-test-suite, glxgears mesa-demos.

ArchISO build problem

Fix the Live CD boot problem: cannot find an unused loop device [1].

Add the earlymodules=loop into the syslinux/archiso_sys32.cfg and/or syslinux/archiso_sys64.cfg file to APPEND variable as parameter to the kernel, e.g.

APPEND archisobasedir=%INSTALL_DIR% archisolabel=%ARCHISO_LABEL% earlymodules=loop
Note: Problem with the X startup was fixed by copying X11 configuration files from Archbang

.

Acronis ISO add to archiso Live CD. syslinux config lines
LABEL acronis
KERNEL memdisk
INITRD /path_to_iso/file.iso
APPEND iso raw

"Acronis True Image Home 2011 Build: #6942 ISO Size: 137.75 MB" can restore images made by "Acronis True Image 2015 for PC Build: #6525 ISO Size: 477.13 MB"

Supported by acronis kernel commands.
