You just answered my question, I think. So you're saying if I access i/o port 0x3f8 (com1) or the lpt port the access will be forworded to the LPC bus? I thought the LPC was just another bridge on the PCI bus and you had to setup the I/O and Memory base address regitsters just like any other PCI bridge device. Sorry for asking what appears to be a stupid question, but I come from the MIPS and PPC part of the world. I haven't done any P.C. programming in 15 years...

I'm trying to figure out how to reroute i/o amd memory space from the pci space to the LBC Bridge. Anyone out there know which registers to touch in the SSI550. I have the SIS

What do you mean by mapping PCI IO/MEM space to LPC bridge ? LPC bridge bridges ISA devices which have different address space than PCI.
