[LinuxBIOS] About VGA question in the EPIA-M motherboard

Hi all,

During compile linuxbios for EPIA-M, have some error message.

The way that I compile as follow:

At first, I build a payload “filo.elf” and put it in /

According to HOWTO document, I fix some setting.

In LinuxBIOSv2-2860/src/mainboard/via/epia-m/Options.lb

default CONFIG_PCI_ROM_RUN=1

default CONFIG_CONSOLE_VGA=1

In LinuxBIOSv2-2860/targets/via/epia-m/Config.lb

romimage "normal"

option USE_FALLBACK_IMAGE=0

#option ROM_IMAGE_SIZE=128*1024

option ROM_IMAGE_SIZE=64*1024

option LINUXBIOS_EXTRA_VERSION=".0-Normal"

payload /filo.elf

end

romimage "fallback"

option USE_FALLBACK_IMAGE=1

#option ROM_IMAGE_SIZE=128*1024

option ROM_IMAGE_SIZE=60*1024

option LINUXBIOS_EXTRA_VERSION=".0-Fallback"

payload /filo.elf

end

In LinuxBIOSv2-2860/targets/via/epia-m/via_epia-m/Makefile

./linuxbios.rom: normal/linuxbios.rom  fallback/linuxbios.rom

cat  /crtbios.rom  fallback/linuxbios.rom > ./linuxbios.rom

.PHONY: all clean fallback-clean normal-clean fallback/linuxbios.rom normal/linuxbios.rom

After compile, it has some error message.

/usr/LinuxBIOSv2-2860/src/lib/version.c

I have trace source code and can’t fix it.

Can you help me to answer what it happen?

Thank for your kindness help.
