Toshiba Tecra M5 BIOS support for Bitlocker in TPM mode?

I have a Tecra M5 (PTM51E) running Vista Ultimate. I would like to
configure Bitlocker using the TPM which is on board. I am aware that
Bitlocker can be used without a TPM, but this requires the user to have
an external token e.g. on a USB drive which they have to insert at boot
time. I would rather use the TPM mode so there will be no need for this.


I have flashed the BIOS to v3.60 which is the latest. Before I was able
to flash the BIOS from within Vista (which is the only option provided
on the Toshiba European support site) I found I had to load the drivers
for the "Value Added Package", without this the BIOS updater simply says
"Computer not supported". Another way to do it is get the BIOS for the
PTM51U from the US site which allows you to write the BIOS updater onto
a bootable floppy.

I used the "Bitlocker Drive Preparation Tool" which is available as an
"Ultimate extra" from Microsoft to set up the partitions as required by
Bitlocker, i.e. my 40 GB hard drive is divided into a main partition to
be encrypted C of 35.7 GB and a separate partition S of 1.5 GB.

I have the "Trusted Platform Module" driver v3.00.1135.00 which is the
latest. Having enabled the TPM in the BIOS (hold ESC when powering on
and then hit F1, second page) I can then go into the Infineon Security
Platform Initialisation Wizard and set the "Platform Owner" and other
passwords etc.

The TPM initialisation wizard automatically opens the Bitlocker config
applet when it finishes (or you can get to it any later time via the
control panel).

The message I get from the Bitlocker applet is:

"Your system is not configured to use BitLocker Drive Encryption. The
BIOS did not correctly communicate with the Master Boot Record (MBR).
Contact the computer manufacturer for BIOS upgrade instructions".

Does anybody have this working on an M5 (i.e. Bitlocker with TPM)? How
did you do it?

I got that message when trying to set up bitlocker on my machine.
I turned off in the bios the boot sector virus protection and was good to
go.
