Dell Patching SMA 12.0


We are starting to use Dell Patching in our environment, and it is working great. 

The only issue is deploying BIOS. Our Dell computers are protected with BIOS "Admin Password" to prevent users' poking around.

When we run the Dell Patching schedule, everything installs fine, except for the BIOS packages, which eventually timed out after the default attempts.

Is there a way to have this successfully installed without having to remove the BIOS password? I want to fix a security issue without opening another hole (removing the password).

The BIOS package installed ok when we removed the password in a testing environment, no matter how many versions the BIOS was behind.

Dell BIOS updates are a problem, indeed.
THis has two causes:
1. Dell BIOSes cannot updated over huge distances (from A01 to A38 or similar) but need steps in between.
2. The driver feed (which is imported from Dell) only contains the latest version.
3. The Dell tool to install the drivers cannot handle passwords.

You can do the following:
1. create a bunch of smart labels with the nessesary BIOS versions. As an example you can use this  which checks for the E7450 with BIOS versions below A24 (you can also click it in the wizard)

SELECT MACHINE.NAME AS SYSTEM_NAME, SYSTEM_DESCRIPTION, MACHINE.IP, MACHINE.MAC, MACHINE.ID as TOPIC_ID FROM MACHINE  WHERE ((BIOS_VERSION < 'A24') AND (CS_MODEL like '%Latitude E7450%'))  2. create a software Item with the BIOS versions where you attach the BIOS version you want to use
3. run a MI with the following:
E7450A24.exe /s /f /r /p=YOURPASSWORD

Notes: if you use Bitlocker, you need to disable bitlocker before and reenable it afterwards. In that case a script would be more helpful.
