have an Dell Latitude E5550 here. Preboot authentication works only with KEXEC command in DMI settings. But with KEXEC command enabled, the boot-process (after PBA-Loginscreen) makes that the notebook is booting up about 1 minute slower -> After the PBA-Loginscreen the Notebook seems to make a pause from about 1 minute until the Windows-Bootscreen appears and windows is loading. Is there any option to speed this up?
