Pleased experienced on EPIA : Linuxbios runs,but smbus errors, no normal rom starting, payload making difficulties

[Mathieu Deschamps]

hello to every linuxBios people,

First, I would like I got V2 started on EPIA C3 Ezra with a null 
payload for a start ...and that truely welcome and pleasant.

I heared a while ago of a half baud rate problem, I 
have no worries on this side. I was trying to to collect
debug serial sent strings via minicom, but i would't advice 
this, it's a mess to configure (in fact for someone like I).
I've just make it with this script that I have joined in there
if it is of any use to somebody :

#!/bin/bash
# Hear !
#
#
( [ "x$1" = "x" ] && echo "Usage $0 log_file" && exit 0)|| $LOG="$1"
ter=`tty`
echo "****************************************************" >>$LOG 
echo " Hear! Boot Log started on `date +%d/%m/%y|%T` " >> $LOG
echo "  tty in use : $ter  from ttyS0 " >>$LOG
echo "****************************************************" >>$LOG

cat -sbA </dev/ttyS0 | tee -a $LOG

It can be lauch that way :
[root@ge] sh hear.sh boot.log
[root@ge] cat boot.log | while read line; do if [ "x$line" != "x$" ];
then echo $line;fi;done

it outputs the bellow log with some non-fatal (?) error
on which, firstly I would like some explanation if you will

****************************************************
 Hear! Boot Log started on 04/05/04|17:27:54 
  tty in use : /dev/pts/0  from ttyS0 
****************************************************

2 LinuxBIOS-1.1.6.0Fallback Mon May 3 18:39:09 CEST 2004 starting...$

Why the normal rom didn't start first, though I config 2 payloads
normal and fallback. I belived fallback were called in case of
fallback BTW of erroring normal rom ?!

3 vt8601 init starting$
4 Slot 00 is SDRAM 04000000 bytes $
5 Slot 01 is SDRAM 04000000 bytes $

6 Slot 02smbus_error: 04$
7 Device Error$
8 is empty$
9 Slot 03smbus_error: 04$
10 Device Error$
11 is empty$

What are these error number refers to ? 
It work though, but these errors while init plus the fallback mode
right from the start, show nothing good for the future deployement
I presume ... anyway

Secondly, I intended to make a IDE elfImagepayload to boot a kernel
on a hard disk, I've read that LinuxBios alone could do that quite
well.
So got mkelfImage 1.16 (i know it's quite old
but i can't find a link to a recent one- BTW please a link to a more
recent one would be appreciated).

I had a error on the build that's seems not to be relevant since 
ending ok ( that's i like to say to myself in these cases )

[root@ge] make;echo "Build : $?";
find :./kunzip_src: No such file
...
Build : 0

So I made  : mkelfImage -kernel=/boot/vmlinuz 
vmlinuz is a kenel bzImage.
It made elfImage, that is wierd :

ls says :
-rwxr-xr-x    1 root     root       901816 mai  5 10:08 elfImage

file says:
elfImage: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
statically linkedfile: corrupted section header size.

It's corrupted, could it be the build "warn"-error message ?

I've done a readelf -x on it too :
