I don't have ICE (Could you recommend one ?) . Therefore I printed post
code at several point of bochs code. 
And I think it stop during VGABIOS execution because it works before option
rom scan procedure. 
I think EPIA bios do something on northbridge settings which VGABIOS
How do you think? 

I found some VGA related registers on northbridge such as 0xfb register
which have 'VGA Enable' 
disable bit. However When I enable it, strangely etherboot doesn't works
and system restarted. 
(My boot configuration is linuxbios -> etherboot -> ADLO payload )
