Aaeon HSB-811P Bios Unlock/Speedstep?

[Superdos]

Aaeon HSB-811P
BIOS v1.6, circa ~2007

I have two of these. They are Single-Board Computers, made for industrial/niche applications.
The main issue I'm having with this is the absence of SpeedStep, either not enabled by default or missing entirely.

Any other hidden features that can be enabled would be wonderful as well.

the board I'm to be testing with is based on an 855GM chipset, contains a Pentium M 1.6GHz Dothan (400MHz FSB) and, like all Dothans, runs pretty warm at full speed all the time. the BIOS already allows for the overclocking of the FSB, and I've played around with that. but, in the end, having speedstep available to have it run at low speed when idle would be a miraculous thing.
I've already flashed 1.6 to this board, hoping there would be speedstep, and alas, there is not.

I'm also including an image of the board I have, sans-heatsink, thanks to some wonderful soul in China that thinks the board is worth $800:


Thank you very much to whomever takes this on. The BIOS is also attached in case the FTP link does not work for some strange reason.
