SMM Mode

Hi all,

I would like to use the processor SMM Mode.
Does anyone work with this processor mode ?
Is this processor mode is supported by Neutrino ? Is there a function to
hook SMI irq ?
Does anyone know if the SMRAM (System management RAM) is relocated by
the OS (default address is 30000h)?
In fact, I would like to hook an SMI irq handler to monitor mainboard
(Celeron 733, chipsets i82810E2/i82801BA(ICH2) and the superio is
W83617HF - superio use SMI irq -) parameters.

All informations on this mode are interesting…
Thanks for your answers,
