Yes, I think I need to set CONFIG_ROM_STREAM=1 in order to have it boot from my FILO payload which then will go load the image in a IDE drive. Thanks.
I got an error when it ties to get_bounce_buffer in elfboot, Don't know if you have the same problem. I dumped out the mem entries info. Looks like the 2 mem entries are all LB_MEM_TABLE(ram config tables to be kept in). So there is no LB_MEM_RAM, (where everyone could use) to allocate the bounce buffer from. Any idea? ======================================================= Wrote the mp table end at: 00000020 - 000001f4 Wrote linuxbios table at: 00000500 - 00000be4 checksum 18e1 lb_size=0x20000 mem_entries=2 mem entry1: type=0x10, start=0, size=0xc4c mem entry2: type=0x10, start=0xf0000, size=0x400 Could not find a bounce buffer...

CONFIG_IDE_STREAM is used to load a payload (such as FILO) from an attached IDE device. This is useful if the flash is not large enough to hold LinuxBIOS+payload, but is probably not what you are looking for. Sorry for the confusion.
