I see that it seems to be there now, thanks!

Now there is another thing I am curious about.

I see that the date of the module added on sourceforge is 5 April.

I also see that there's a firmware update for the box I am building,
as of the same date:
http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=19975

and its release notes include:

Other:
- Added: ACM for Intel(R) Xeon(R) Processor 5600 series update to
   production V1.2

Does that mean that the BIOS for this box is one of those that (as the
MLE Guide puts it) "may already have the correct SINIT AC module loaded"
at TXT.SINIT.BASE?

What does tboot do in that case?  Can tboot be used without specifying
an ACM as the last module in grub, if the module is already loaded by
BIOS?  Does tboot unconditionally load the module named in grub?  Or
does it compare the Date fields and use the most recent (as the Guide
suggests)?

If the release note does mean that this BIOS includes the ACM, should
I assume it's the same version as the one published on sourceforge,
since they happened the same day?  The release note says "V1.2" and
the filename on sourceforge is X5600_SINIT_16.BIN but I'm not sure
that "V1.2" and "16" belong to the same numbering scheme.

Please excuse the spray of questions ... if the box had arrived yet
I would probably just be playing with it to see what happens, but
instead I'm getting fidgety waiting. :)

Thanks,
