Resident SIS expert

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...
