Booting an Operating System
5-23
You can enable the Setup Password option of the Advanced CMOS Setup screen of
AlphaBIOS to limit access to AlphaBIOS Setup mode, but allow booting of the
operating system. You can enable the Startup Password option of the Advanced
CMOS Setup screen of AlphaBIOS to limit access to AlphaBIOS Setup and
operating system booting.
If the Startup Password has been selected from the Advanced CMOS Setup screen
of AlphaBIOS, then you will be prompted for a password before the Windows NT
system is booted or before you can enter AlphaBIOS Setup, after you press the F2
key.
Figure 5-5 shows the Windows NT boot screen with the password authentication
window superimposed. In this case, the Startup Password option has been selected and
the user must type a password before the operating system will boot or before the user
can enter AlphaBIOS Setup mode. A similar screen would prompt for a Setup
Password if that has been selected from the Advanced CMOS Setup screen of
AlphaBIOS and you pressed F2 to enter AlphaBIOS Setup mode before the operating
system was booted.
