Boot Logon fails to load with Black Screen Blinking Cursor
Boot logon does not load. System freezes at a Black Screen with a blinking cursor. This is related to Intel MEI driver the SecureDoc Linux preboot uses.
Symptoms:
Following the WinMagic SecureDoc Boot Logon vX.X.X Please tap A for alternate boot screen, the device immediately produces a Black Screen Blinking cursor.
The end user will be unable to press F10 to break autoboot if the system is still being Provisioned, or configured for Permanent Autoboot.
The end user will be unable to collect preboot logs through F7, or through the config file on a usb.
Environment:
Legacy BIOS, v5 boot logon.
Probable Cause:
The boot logon fails to load as the result of a failed handshake with the Intel MEI firmware. This is related to the Intel MEI driver the SecureDoc Preboot uses. This can also outline an issue with the hardware.
The Intel Management Engine Interface (Intel MEI, previously known as HECI) is the interface between the Host and Intel ME. This interface is exposed to the host as a PCI device. The Intel MEI Driver is in charge of the communication channel between a host application and the Intel ME feature
Proposed Workaround:
We suggest the following steps to implement mei-me.blacklist=yes as a Boot Parameter. This prevents the initialization of the Intel MEI driver, and allows the boot logon to load.
Standalone/Single device
Boot the system to the bv4 boot logon by tapping the a key as the system start.
Login with a SecureDoc Administrator.
In Windows Load the SecureDoc control center.
Login with the same SecureDoc Administrator.
Go to Boot Control > Advanced Settings
Click the Advanced Settings tab.
In the Boot Parameters field enter mei-me.blacklist=yes
Click Apply.
Restart the device to verify v5 will load.
