That board has a VIA vt82c686b south on it? I built linuxbios for a
similar VIA board (endat) with an 8601 north and vt82c686b south. That
won't work with the epia or epia-m configs. but you can go from the
via/vt5426 config. You are perhaps getting garbage serial output because
you're setting up serial for the wrong superio.
Have you figured out how to enable flash memory write? I have two 686
datasheets which seem to contradict one another on how it's done. one
appears like the 8231 south, and another alike the sis630.
