I doubt 0x402 does anything on Xen, aside from beeing > trapped in qemu if configured correctly, but I havn't tried. If you really want this, I'm okay with a patch that introduces CONFIG_DEBUG_PORT, and has Kconfig do all the magic of selecting the preferred debug port. That okay? -Kevin

As far as I know, it's a Bochs BIOS thing (see rombios.h). Bochs seems to have lots of debug ports (eg, 0x400-0x403) - I'm not sure why. Qemu also has code for port 0x402 if DEBUG_BIOS is enabled in hw/pc.c - though it's much easier to use the isa-debugcon command line option. Also note that the DBUG() method in SeaBIOS' src/acpi-dsdt.dsl is also setup to use port 0x402 right now. > I really doubt picking up a new debug port in xen would be acceptable > because 0xe9 has been around for a long time and it would certainly > break legacy code. Is the issue that writes to 0x402 are causing an issue on Xen, or just that you don't see the debug output? What's the origin of 0xe9 - is it a "standard" for debug output? What does Xen do today on writes to 0xe9? -Kevin

Seabios on Via pc2500e
by Elisenda Cuadros 06 Jan '12

06 Jan '12

Hello list, I´m trying to boot a Via pc2500e motherboard with coreboot and seabios (built from coreboot, stable). Everything is ok, I can see the bootmenu (I have only one hard disk at the moment), but when I press "1" it seems coreboot is restarting entering in a loop. Is this a normal behaviour? I tried attaching a bootorder file with cbfstool with same result. I attach you the log. Thanks in advance. Best regards, Elisenda

Hi Kevin, It took a bit longer but now i have your vga patches/updates working on Geode GX2.(i had to solve a bug in my VSA first) Not all of your patches did apply cleanly. I made this patchset to test the code on GX2 and it works.:) Signed-off-by: Nils Jacobs <njacobs8 at adsltotaal.nl> Thanks, Nils.
