(Usb sticks and SD etc flash cards are other possible options.) ..boot it with 'knoppix toram ' and see what happens, if that fails to do what we want, try e.g. 'knoppix toram xmodule=ati ', more ideas to try append to the boot command: ftp://ftp.uni-kl.de/pub/linux/knoppix/knoppix-cheatcodes.txt .."xmodule"'s I'd like to see compared, is radeon, radeonhd, and ATI's own fglrx, and on Nvidea's, nvidea and nouveau. ..note that you _may_ have to use knoppix64 to boot a 64bit kernel on a 64bit cpu, and knoppix32 or somesuch to boot a 32bit kernel on 32bit cpus, I'm not up to date on current knoppix boot cheatcodes. _Play_around_. ;o) -- ..med vennlig hilsen = with Kind Regards from Arnt Karlsen ...with a number of polar bear hunters in his ancestry...
