Password Bypass; Hardware Startup - AlphaPC 164LX User Manual

This chapter contains information about troubleshooting hardware and software
during AlphaPC 164LX startup.

8.1 Password Bypass

AlphaBIOS provides password protection. However, Password Bypass is provided
for system setup or startup when the AlphaBIOS password is unavailable.
Password Bypass is enabled by inserting jumper CF3 in the J27 System
Configuration Jumper Block (see Figure 3-1). This disables the AlphaBIOS
password verification and enables the user to set up or start up their system without
the AlphaBIOS password. Password Bypass also clears the password.
