A Dell System Number ending in 0001 means that the Master Password Lockout setting is enabled in BIOS. This is the BIOS checkbox that disables master-password support.
What the 0001 suffix means
In Dell BIOS, this setting is usually named “Master Password Lockout” or “Enable Master Password Lockout”. When the checkbox is selected, BIOS disables master-password support and the password screen shows the -0001 ending. Therefore, 0001 identifies this setting state; it is not a ready-made password.
