The problem is my m8 Portege R100 somehow got screwed up, it's missing some system files so explorer cannot start. Without explorer i cant replace the missing stuff so i though no big deal, just boot Knoppix from an external dvd-rom and fix it. But the lappy wont recognise the USB dvd-rom, and i dont have an external floppy either. After a bit of research it seems the Portege R100 is quite dodgy at USB support, but some people did manage to boot from an external drive (according to Google at least). So any suggestion of what can i do, is there a way to boot from USB devices ?
P.S. I'm sure the boot priority is correct. It's CD->FDD->LAN->HDD
