Intel® Server Board SE7320SP2 & Intel Server Board SE7525GP2 TPS System BIOS
Revision 2.0
101
Administrator has control over all fields in the setup, including the ability to clear the user
password.
If the user enters three wrong passwords in a row during the boot sequence, the system will be
placed into a halt state. This feature makes it difficult to break the password by “trial and error.”
The BIOS Setup may provide an option for setting the EMP password. However, the EMP
password is only utilized by the mBMC; this password does not affect the BIOS security in any
way, nor does the BIOS security engine provide any validation services for this password. EMP
security is handled primarily through the mBMC and EMP utilities.
