E' la tua machina una laptop?

D: Il mio mouse PS/2 non funziona!

R: Se il puntatore del mouse in modalita' grafica si muove in maniera
casuale, il mouse sta usando un protocollo non riconosciuto. In questi casi
l'unica soluzione consiste nel fare l'avvio in modalita "expert" e
configurare il protocollo corretto per il mouse. Se invece il puntatore
compare in mezzo allo schermo e non risponde affatto ai movimenti del mouse,
probabilmente avete una scheda madre con un noto bug del BIOS (ultimamente
questo problema si e' manifestato frequentemente sui portatili). Scrivete
	knoppix pci=irqmask=0x0e98
alla schermata di avvio e verificate se serve a qualcosa. In alternativa
potete cercare un aggiornamento per il BIOS del vostro computer (che 
potrebbe risolvere anche altri problemi).

knoppix tohd=/dev/hda1              Copy CD to HD partition and run from 
there
knoppix fromhd=/dev/hda1            Boot from previously copied CD-Image
knoppix testcd                      Check CD data integrity and md5sums
expert                              Interactive setup for experts

Hint: Using the default DE-bootimage, SYSLINUX boots with german keyboard
layout. The '=' letter is located at Shift-0 on this keyboard (just in
case you want to change keyboard and language with lang=us).

*) Try "knoppix pci=irqmask=0x0e98" if (you have a notebook and) your
PS/2 mouse doesn't work. (Possibly caused by a BIOS-flaw on your board,
BIOS updates can help.) Sometimes, switching to the text console with
Control-Alt-F1 and back to the X-screen with Control-F5 solves the
problem without rebooting, since the X server reinitializes the mouse
driver during that procedure.

If your KNOPPIX CD makes strange noises during boot, or you see
frequent errors like "cloop: read error", or programs on your KDE
desktop keep crashing randomly, then your CD image is probably defective
or incomplete, or your CD-burner created a defective CD due to wrong
writing speed or bad media. This is the most common error reported.
Please boot with "knoppix testcd" to check if the CD is OK, and/or even
better, verify the MD5 checksums that are present on the mirrors before
writing the CD. In some cases, defective IDE controllers cause this
error if you have DMA enabled. Also, please read the KNOPPIX-FAQ.

In case of a failing hardware autodetection, try booting with any of
the "no-" options as shown in the table above, like in
    knoppix noagp noaudio noddc noapm noapic nodma nopcmcia noscsi nousb
to skip some critical parts of the autodetection system.

The "noswap" option is useful for a forensic analysis without touching
existing swap partitions.

Some Boards apparently don't pass the proper memory size to the
linux-kernel. It may cause the message "Panic: cannot mount root file
system" and the system hangs. Use "knoppix mem=128M" to solve that
problem if your system has 128MByte memory for example (caution:
you MUST use a capital "M" here).

The "expert" mode provides a very simple interface to loading additional
Kernel modules from floppy disks (ext2 or vfat), plus interactive
configuration of mouse/keyboard/soundcard/xserver. "expert" mode 
supports the same boot options as "knoppix".
