If I understand the question correctly Juergen want to tell the chipset to issue a IRQ not a SMI. There is no SMM code in LB.

I try to write a native sound driver for the Geode GX1/5530a Companion chip. Problem here: The sound chip only generates SMI. Does anyone knows a trick or a chipset switch that let me forward this SMI to a regular IRQ? Its too ugly to use a polling loop.... ;- )
Sorry. I think I must explain: I'm using linuxbios on this Geode system, so there is no SMM emulation of the sound hardware. Thats why I'm searching for a solution to forward the SMI to a regular IRQ. Has someone experience in programming this SMM code? Maybe a short routine that only triggers a regular interrupt when an SMI occures would help.
Is there some reason to continue to use SMI? why not just drive the hardware directly w/o smi?
