thanks Guth and darkscot!
i added the line "default=Zenwalk" in the conf file and tried "lilo -v", but that gave an error at line such and such. so i had to restore my lilo. anyway, probably i did something wrong. but again, i was doing half-heartedly on friday night... so yeah. that may be why...
i will give another shot this weekend. maybe tomorrow if i am not too drunk.
good weekends for both of you!
