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.
- Change / show the screen resolution

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.
