<DIV>Hello! Long time no see.<BR><BR>I am trying to use framebuffer using linuxbios. So I am about to use ADLO.<BR><BR>linuxbios -> etherboot -> ADLO -> Bochs -> VGA BIOS -> LiLo -> Linux<BR>( flash rom ) ( remote server ) (MBR) <BR>Is that sequence right ? And I adopt the code which Andrew lp wrote on mailing list <BR>to enabel VGA device. But etherboot didn't work. ( Before enabling VGA device , it worked. ) .. The debug message is below.<BR><BR>why didn't etherboot worked ? I think that the difference between enabling VGA and disabling VGA is PCI bus scanning and resource allocation part. Who does know this problem ?<BR><BR>Thanks for your attention and your help.<BR><BR>=============================================================================<BR>.0</DIV>
