I tried with friend laptop. It didn't give anything. Maybe I just can't use
serial cable and minicom :( I hope better debug next time. Superio  is
w83627hf in both mainboards (ms-6178 and ms-6337)

Kernel config (I am no sure if it's the same but it is small) is minimal. It
boots with proprietary bios and it is just for testing. I had no success
with filo either. It is used with ubuntu dapper sources. I'll try to attach
it this week.

Last two are pci cards. Not necessary just now.

lspnp: /proc/bus/pnp not available
might help if I change some settings of proprietary bios.

Here is minimal kernel config. I  hope it is right version.

OK, on the MS-6178 I can say for sure that serial output works in LinuxBIOS.

Quick minicom tutorial:

$ minicom -s
  -> Serial port setup
  -> Press A and enter your COM device (ttyS0 or ttyS1 or ttyUSB0 or so)
  -> Press E and choose "115200 8N1" (default)
  -> Disable Hardware and Software Flow Control (via F and G)
  -> Press enter to leave the menu
  -> Save setup as..
  ->   Enter "lb"
  -> Exit from minicom

So, from now on you can use this config like this:

$ minicom -o lb

So this is the ms-6337, I guess? It's an i815 chipset which is similar,
but not quite the same as i810. Some more work is probably needed for that.

Strange. Maybe you have to enable some "PnP" option in the BIOS for
lspnp to work?

I also managed to get some serial output after all. It's attached too :-)
Somehow some af a letters are shown as i. There is some Pci bad id messages
and it Cannot load ELF image.

Cool, Good job! Looks like your getting some weird characters before  
each line. This could be caused by the wrong serial speed setting.  
What do you have minicom set to?

Just a guess the lspnp: /proc/bus/pnp not available could be cause by  
your LPC Interface Bridge. Eithor it is not enabled or not configured  
for PNP maybe?

Attached minicom log with ms6178 revision 2948. It seems even better than
slightly modified version earlier.

superiotool_output is from ms6337. Superio is w83627hf-aw.

Please check the dimm size translation tables, in northbridge.c and
raminit.h. If you're using the i810 ones, I'm fairly sure they need to
be modified, that could be why your elfload is failing. Also check that
video is either disabled or the vga framebuffer size is subtracted from
the memory size in northbridge.c (look for ram_resource()). And please
try with only a single dimm, unless you've worked on it I think ram init
is only working correctly for one dimm.

Good luck!
Corey

Looks like you may have something wierd going on with your SuperIO or  
LPC Bridge:

If I was you I would look deeper into these errors.

Using just one dimm made it better. It gave last line FILO version
0.5(desktop) and date. Image is slightly modified.  I hopefully
disabled
onboard  vga. It is set to 2.0 and off.  Also  other  things  in my opinion
not so important now as paraller port and floppy are set off. Could
unconnected floppy drive affect to PNP errors?

northbridge is changed by just using device number 0x1130 instead of 0x7120
in northbridge.c

Filo.elf is different this time too.

Is the ram working good enough with one chip? Does elfload tell anythig to
you?

Have you tried ram_check() in auto.c? Sounds like you may have some  
memory initialization problems like I was having. You can try this:

1. Enable debugging output in raminit.c, build and run to get the bootlog.
/* Uncomment this to enable debugging output. */
#define DEBUG_RAM_SETUP 1

2. As root with the factory bios do a lspci -xxx.

3. Compaire the 00:00.0 Host bridge from lspci -xxx to the Northbridge  
following SDRAM init: PCI: 00:00.00 from your bootlog. Especially the  
DRB registers. I had two DRB registers that were supposed to be  
reserved but they are not. I set those and boom it booted:-)

Hope that helps.
