LinuxBIOS have three parts
Also the flash will contain three
linuxbios.rom
Normal+Fallback+Failover.
Failover will be used to init 64K above
rom access.

Subject: [LinuxBIOS] The two load
RAM codes.
I
am studying the LinuxBios project. I have a question about the RAM code: from
Makefile, it seems that LinuxBios could load codes from FLASH to RAM twice,
first for linuxbios_ram, second for so-called payload. My understanding is
correct or not. However, also from Makefile, it seems that linuxbios is
dependent on LINUXBIOS_RAM_ROM, but doesn't include it. The below is abstracted
from a Makefile for via epia-m based on LinuxBiosV2-2534:
linuxbios:
crt0.o $(INIT-OBJECTS) $(LINUXBIOS_APC) $(LINUXBIOS_RAM_ROM) ldscript.ld
$(CC)
-nostdlib -nostartfiles -static -o $@ -T ldscript.ld crt0.o $(INIT-OBJECTS)
$(CROSS_COMPILE)nm
-n linuxbios | sort > linuxbios.map.
So,
there is no action on LINUXBIOS_RAM_ROM. Does it mean linuxbios_ram is not very
important. Even without it, the system is also ok?
