This in my opinion sounds like setting yourself up for headaches.

If it were me, I'd put a test in the beginning of the task sequence that checks 
the BIOs version and fail out cleanly if it isn't at a good version.  Then have 
a "utility" task sequence that the desktop techs can run that is 32bit and can 
be used to update the BIOs.  Then kick off the build again.

That's just me.

Subject: [MDT-OSD] Modify boot image assigned to TS on the fly?

Currently I am not able to update BIOS until I am in the full OS since Dell 
BIOS update is a 32bit application.  There was talk in forums about releasing 
64bit versions of BIOS update tools, but 7 years has passed with no action.  
Usually, updating BIOS is OK to do after the OS is loaded, but there are times 
when an out-of-date BIOS is a block to the installation of Windows and in those 
cases it would be great to deploy an updated BIOS before we reboot into the 
full OS.  So after the task sequence starts I'd like to be able to stage 
different WinPE image depending on whether I want to reboot into 32bit WinPE or 
64bit WinPE.  It would be cool to specify the WinPE boot disk to stage in the 
reboot step rather than have it be locked in for the whole Task Sequence.

Does anyone know of a way to change the boot image assigned to a task sequence 
on the fly, and let it get restaged by the Reboot step?

Do you think the work being done with nested Task Sequences might eventually 
help?  Will it allow the nested TS to have a different WinPE boot disk assigned 
to it and restage WinPE before reboot steps in the nested TS if the clild TS 
has a different WinPE boot disk assigned to it than the parent TS?
