Hello FreeBSD Core Team!
The first thank You about russian documentation FreeBSD.
I have one problem with loader.
Situation: I have 2 HDD - first (master) FreeBSD 5.0 installed; second (slave) - Windows - at one IDE both HDD.
FreeBSD loader show me at startup:
F1 FreeBSD
F2 Dos
F3 Drive1

And one DENGEROUS situation I had: when I press F3 (Drive1) at startup - I'll couldn't load FreeBSD any more, I shoul boot from install FreeBSD CD and reinstall.
