Thanks for the quick reply! This board uses a National PC97317 Super-I/O chip, and the only reference to a serial port I see in auto.c is a call to function pc97317_enable_serial(), where it passes the value of TTYS0_BASE. I guess that means something could be wrong with pc97317_enable_serial(), which I'll try to grok tomorrow.
thanks, Jonathan

You also need to change it in the target's auto.c or cache_as_ram_auto.c, you'll need to change both the IO base and the com port. They're usually defines at the start of the file that you have to change.

Hi, I have a perfectly working coreboot v2 image for a GX-1 target of mine, but
when I tried to switch it from COM1 to COM2, I can't make it work. I thought it would be as easy as updating TTYS0_BASE from 0x3f8 to 0x2f8 in Options.lb, but that doesn't work. What's the trick to making this work?
thanks, Jonathan
