Hi Andrew and all

I installed freebsd 6.0, complied the kernal and  put
the polling setting to sysctl.conf

after rebooting, it shows "kern.polling.enable is
deprecated" use ifconfig (8)

Do you have any ideas?

2/ how can I page up the see previous boot message in
the console?

Thank you for your help
