Thanks, I understand. I was just wondering if there were in fact verified "bios code bugs" or if the
table entries *alone* controlling powerplay MHz values and fan control RPM vs temperature settings
were the *only* reason the BBA reference cards from Visiontek, ASUS, et. al. were running hot with slow fan RPMs and using idle speeds of 500MHz vs. 160 MHz.
I thought I'd seen it implied by some that the hot temeperatures and high idle speeds were the
sole problem of a mis-set BIOS control table, though seeing all the talk of using MSI BIOS as a basis
to change the RBE BIOS tables made me wonder if it was confirmed that there were code related
(beyond default table entries) changes that were significant.
I remember hearing that in the case of various 3870 boards, all one had to do to improve the
Powerplay MHz and fan speed selections was to change the table entries in one's stock BIOS with RBE.
I'm not so sure if those are the only needed / beneficial changes for the BBA Visiontek / ASUS / et.al. reference HD4850 boards though.

The RBE changes some common values like voltages or fan speeds, it cannot go in and apply patches to faulty code that prevents features from working.
So no, you can't use it to enable powerplay if it isn't working (a bug, not a disabled feature).
