How can I change Write cache diables on w2kadv Domain Controller

Dear all:

I recently upgraded my win NT 4.0 server to Win2kAdv Server.
its a DC.

When I enable the boot device write-cache,
W2KADV DC changes it back to non-write-cached
upon next boot. W2kadv does this by default on a DC
without power protection.

I want the boot device cached anyway,
and without a ups. so I need it overridden.

As you can imagine, without a write cache,
the performance suffers greatly.

I understand thier reasoning,
I just dont agree, and its my network.
I know the risk. I am fully willing and able
to live with it. I have backups, and ERD's and all that.

My second drive IS write cached and stays that way,
so I KNOW it is possible to make write cacheing stay on.

How do I get the boot device write cache to stay on
without using a ups? Any hacks, cracks or tweaks appreciated.

Thank you,
James W. Long
