[LinuxBIOS] ADLO with EPIA-M LX2

[Anton Borisov]

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).

    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.

See if you can load any payload at all or if its just the ADLO payload
thats causing you trouble.  Try memtest without the video bios so you
don't have to change any settings.
