The Thomson IP1000 is designed by Thomson Electronics. It is the RCA RM4100's big brother. It is a great little set-top-box for coreboot. Linux has never been able to run on this board until now. Maintained by Joseph Smith.
A full bootlog of this board running coreboot is available for reference.

VGA vs. Headless
Before building coreboot for the RCA RM4100 there are a few settings to consider. Depending on whether you want VGA support or not, you might have to modify some files.
See VGA support for information on how to add support for the onboard VGA controller.
like instructed in the INSTALL directions and then edit the file Config.
MENULST_FILE = "hda3:/boot/filo/menu.lst"
to (menu.lst is a symlink to grub.conf and FILO does not like that)
MENULST_FILE = "hda1:/grub/grub.conf"
to boot to GRUB on the Compact Flash card or
MENULST_FILE = "hdc1:/grub/grub.conf"
to boot from the harddrive.
#SERIAL_SPEED = 115200
SERIAL_SPEED = 115200
to insure we get output to the serial console. That should be it. Now you can run
again to build your payload ELF file. Once that finishes copy filo.elf to the /tmp directory, or you can adjust targets/thomson/ip1000/Config.lb to point to where filo.elf is.
You can further reduce the size of filo.elf by disabling various unneeded options in FILO's Config file (e.g. support for filesystems you don't use).
See the Build HOWTO for information on how to build coreboot for this board.
At last you're ready to flash cboot.rom to your IP1000. Unfortunately there is not really an easy way to do this. The IP1000 has a PLCC32 socket for the firmware chip so you can take the chip out and use the Hot Flash method or a programmer device. After you have Linux running you can always use flashrom.
