because of technical reasons i am obliged to boot from floopy drive

the
  > boot -a
command gives me the possibility to choose the root partition and to 
boot my installed system.

wsconscfg: /dev/ttyEcfg: Device not configured
wsconscfg: /dev/ttyEcfg: Device not configured
wsconscfg: /dev/ttyEcfg: Device not configured
wsconscfg: /dev/ttyEcfg: Device not configured
wsconscfg: /dev/ttyEcfg: Device not configured

(some other lines, starting inetd, cron and then:)

May 16 14:24:52 getty[179]: /dev/ttyE1: Device not configured
May 16 14:24:53 getty[181]: /dev/ttyE3: Device not configured
May 16 14:24:53 getty[180]: /dev/ttyE2: Device not configured
May 16 14:24:53 getty[178]: /dev/ttyE0: Device not configured

and i can't do anything then, no prompt, no shell, and i have to turn 
power off.

I've got the
wsconscfg: /dev/ttyEcfg: Device not configured
error message even if i run "/etc/rc.d/wscons start" after i boot from 
floppy (without -a) and mount/chroot.

thanks for you help
help i'm asking again
