Pleas look into the knoppix-cheatcodes.txt (attached, and on your CD).
You will need the boot option for sony or transmeta notebooks.

CHEATCODES AND HINTS FOR KNOPPIX V3.1
==============================================================================
(last update: 01.01.2002)
These options (can be combined) work from the SYSLINUX bootprompt:
knoppix lang=cn|de|da|es|fr|it|pl specify language/keyboard
knoppix lang=ru|sk|tr|tw|us specify language/keyboard
knoppix desktop=fluxbox|gnome|icewm Use specified WM instead of KDE
knoppix desktop=kde|larswm|twm Use specified WM instead of KDE
knoppix desktop=wmaker|xfce Use specified WM instead of KDE
knoppix screen=1280x1024 Use specified Screen resolution for X
knoppix xvrefresh=60 Use 60 Hz vertical refresh rate for X
knoppix xserver=XFree86|XF86_SVGA Use specified X-Server
knoppix xmodule=ati|fbdev|savage|s3 Use specified XFree4-Module
knoppix 2 Runlevel 2, Textmode only
knoppix floppyconfig Run "knoppix.sh" from a floppy
knoppix no{apic,agp,apm,dma} Skip parts of HW-detection (1)
knoppix no{firewire,pcmcia,scsi} Skip parts of HW-detection (2)
knoppix no{swap,usb} Skip parts of HW-detection (3)
failsafe Boot with (almost) no HW-detection
knoppix pci=irqmask=0x0e98 Notebooks, if PS/2 mouse doesn't work
knoppix ide2=0x180 nopcmcia Boot from PCMCIA (transmeta notebooks)
knoppix mem=128M Specify Memory size in MByte
knoppix noeject Do NOT eject CD after halt
knoppix-txt No framebuffer at startup
knoppix vga=normal No-framebuffer mode, but X
knoppix blind Start Braille-Terminal (no X)
knoppix brltty=type,port,table Parameters for Braille device
knoppix wheelmouse Enable IMPS/2 protocol for wheelmice
fb1280x1024 Use fixed framebuffer graphics
fb1024x768 Use fixed framebuffer graphics
fb800x600 Use fixed framebuffer graphics
knoppix keyboard=us xkeyboard=us Use different keyboard (text/X)
knoppix testcd Check CD data integrity
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).
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. 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 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).
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.)
The "expert" mode provides a very simple and not yet well tested 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".
The "floppyconfig" option allows you to reconfigure the system after
autoconfig, or install your own config files, by mounting a floppy disk
and running a bourne shell script called "knoppix.sh" from the root
directory on this floppy. There is a GUI to create such a configuration
floppy disk calles "saveconfig" (also located in the KDE menu under
"KNOPPIX", but experts also know how to do this by creating their own
shellscripts. From Version 2.1 and up, a file called "knoppix.sh", if
located in the toplevel KNOPPIX directory on CD, will also be executed
at startup. This makes ist easier to create customized versions without
having to change anything on the compressed filesystem KNOPPIX/KNOPPIX.
Starting from Version 2.0, SCSI-Emulation is active for all CD-Roms,
so IDE CD-Writers should work with the installed versions of cdrecord
and cdrdao (or the graphical frontends thereof, cdbakeoven, xcdroast
and gcombust).
If your BIOS does not support el torito booting from CD, you can create
a bootable floppy disk by issuing (on Linux)
dd if=mounted_cdrom_directory/KNOPPIX/boot.img of=/dev/fd0 bs=18k
or, in case of DOS, use the rawrite.exe program provided in the
KNOPPIX directory on CD.
If you wish to remaster the CD, please don't forget to specify
-b KNOPPIX/boot.img
for the german version of the bootfloppy, or
-b KNOPPIX/boot-en.img
for the english version, as option to mkisofs. Otherwise your CD
won't be bootable. The directory KNOPPIX, containig the compressed
filesystem file "KNOPPIX", must be located in the top level
directory of the CD.
Caution: X-Screensaver: Don't start xlock or any screensaver that
requires a password. There are no default passwords on KNOPPIX,
i.e. all accounts are LOCKED unless you explicitly set a password.
See also README_Security.txt about this issue.
If you accidentially hit the screensaver button in KDE,
switch to one of the textconsoles by Control-Alt-F1 and kill
the screensaver (or just set a password for the knoppix user).
If you would like to edit your X-Server configuration manually
(/etc/X11/XF86Config-4 for XFree86 V4.x), use "knoppix 2" to boot
into runlevel 2 (textmode only) and type "ls /usr/X11R6/bin/XF*"
to see a list of all available X-Servers. Once you verified
that your X-Server is working correctly, you can run the X startup
script with "/etc/init.d/xsession start".
