After a time far from Knoppix because of a Synaptic problem, I’m using it again as my main OS.
When I enter cheat codes "knoppix keyboard=es xkeyboard=es" Spanish keyboatd works fine, but with
LABEL knoppix
KERNEL linux
APPEND lang=en keyboard=es xkeyboard=es apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1

in /mnt-system/boot/syslinux/syslinux.cfg
it doesn’t.

Is this the file I have to edit?

Thanks.
