DMI Settings Dell Latitude E6400?

Hello

I trie to encrypt my Dell Latitude E6400 Notebook with FDE (ZCM 11.2.1MU1).
By default, there is no entry for this hardware.

So I set some entries in the following order....

First attempt:
[Dell Inc.,Latitude E6400]
DMI_SYS_VENDOR=Dell Inc.
DMI_PRODUCT_NAME=Latitude E6400
KICKSTART=KEXEC
KERNEL=/boot/bzImage-acpi

Result: Frozen PBA Window (Windows will start ind 10 Seconds...)

Second attempt:
[Dell Inc.,Latitude E6400]
DMI_SYS_VENDOR=Dell Inc.
DMI_PRODUCT_NAME=Latitude E6400
KERNEL_PARAM=pci=snb-enable-ahci-to-legacy

Result: Blinking cursor on a black window after PBA! Nothing more...

Third attempt:
[Dell Inc.,Latitude E6400]
DMI_SYS_VENDOR=Dell Inc.
DMI_PRODUCT_NAME=Latitude E6400
KICKSTART=BIOS

Result: Frozen PBA Window (Windows will start ind 10 Seconds...)

Is there anyone who knows the correct DMI-Settings parameters?
Thanks for reply..
