Hi.
I have compiled ADLO from LX1 (freebios--devel--1.0--base-0.tar.bz2).
Pure BOCHS BIOS ~58k. Payload with VGABIOS - 124k.
My Config.lb is below:
=
target epia-m
mainboard via/epia-m
option MAXIMUM_CONSOLE_LOGLEVEL=8
option DEFAULT_CONSOLE_LOGLEVEL=8
option CONFIG_CONSOLE_SERIAL8250=1
option ROM_SIZE=256*1024
option HAVE_OPTION_TABLE=1
option CONFIG_ROM_STREAM=1
option HAVE_FALLBACK_BOOT=1
option FALLBACK_SIZE=0x30000
option _RAMBASE=0x00004000
romimage "fallback"
option USE_FALLBACK_IMAGE=1
option ROM_IMAGE_SIZE=0x10000
option ROM_SECTION_OFFSET=0x10000
option ROM_SECTION_SIZE=0x30000
option LINUXBIOS_EXTRA_VERSION=".0Fallback"
payload /home/anthony/src/payloads/adlo.elf
end
buildrom ./linuxbios.rom ROM_SIZE "fallback"
=
Some comments regarding FALLBACK_SIZE. This is done intentionally to
include VIA's VGABIOS into fallback portion.
linuxbios.rom being composed this way is written into flash chip.
Unfortunately I wasn't able to load ADLO payload (see messages below).

Moving GDT to 0x500...ok
Wrote linuxbios table at: 00000530 - 00000b28 checksum 97d3
Welcome to elfboot, the open sourced starter.

Version 1.3
33:stream_init() - rom_stream: 0xfffd0000 - 0xfffeffff
Found ELF candiate at offset 0
Cannot Load ELF Image

I assume this is a problem with improper configuring ROM_IMAGE_SIZE,
ROM_SECTION_OFFSET in my example. I did increase it to 0x20000 value. And I've
got this error while compiling with ROMCC:
=
./romcc -mcpu=c3 -O -I/home/lx/src/LinuxBIOSv2-2080/src -I.
-I/home/lx/src/LinuxBIOSv2-earlymtrr.c:21.45:
Integer constant to large
=
Where I've done wrong? Does anybody experienced with ADLO applying to
LX2 recently?
Thanks.
