The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

The RCA RM4100 was originally designed by Thomson Electronics and was called the IP1000. I was then manufactured by RCA and named the RM4100. It is a great little set-top-box for coreboot.

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.

Headless (no VGA)

You have the ability to build a "headless" version of coreboot that will only output to the serial console:

Edit targets/rca/rm4100/Config.lb and change: 

# option ROM_SIZE = 1024 * 1024
option ROM_SIZE = (1024 * 1024) - (64 * 1024)

to 

option ROM_SIZE = 1024 * 1024
# option ROM_SIZE = (1024 * 1024) - (64 * 1024)

Also, change: 

option CONFIG_CONSOLE_VGA = 1
option CONFIG_PCI_ROM_RUN = 1

to 

option CONFIG_CONSOLE_VGA = 0
option CONFIG_PCI_ROM_RUN = 0

Change 

option CONFIG_VIDEO_MB = 8

to 

option CONFIG_VIDEO_MB = 0

Edit src/mainboard/rca/rm4100/Config.lb and comment out these lines so it looks like this: 

#    chip drivers/pci/onboard		# Onboard VGA
     device pci 2.0 on end		# VGA (Intel 82830 CGC) 
#      register "rom_address" = "0xfff00000" 
#    end

VGA

If you do want VGA you can choose how much memory is pre-allocated for VGA. Possible options are: 

## 0 for No memory pre-allocated (Graphics memory Disabled)
## 512 for DVMT (UMA) mode, 512K of memory pre-allocated for frame buffer
## 1 for DVMT (UMA) mode, 1M of memory pre-allocated for frame buffer
## 8 for DVMT (UMA) mode, 8M of memory pre-allocated for frame buffer

To adjust this edit targets/rca/rm4100/Config.lb, edit the line 

CONFIG_VIDEO_MB =

and change it to any of the options above. Note: Remember that if you do want VGA you will need the VGA BIOS file (vga.rom).

Payload

Next you will need to prepare a payload. For this tutorial I will use FILO to boot from a hard drive (Fedora Core 7). In the FILO directory run 

make

like instructed in the INSTALL directions and then edit the file Config.

Change: 

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 (if you have the HD hack installed).

Change: 

#SERIAL_SPEED = 115200

to 

SERIAL_SPEED = 115200

to insure we get output to the serial console. That should be it. Now you can run 

make

again to build your payload ELF file. Once that finishes copy filo.elf to the /tmp directory, or you can adjust targets/rca/rm4100/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).

Building coreboot

Now we are ready to build coreboot. 

$ cd ~/coreboot-v2/targets
$ ./buildtarget rca/rm4100
$ cd rca/rm4100/rm4100
$ make

If you're using VGA you need to prepend your video BIOS to the coreboot.rom file. Copy your VGA BIOS file (vga.rom) to the ~/coreboot-v2/targets/rca/rm4100/rm4100 directory and then: 

cat vga.rom coreboot.rom > bios.bin

Flashing coreboot

At last you're ready to flash bios.bin to your RM4100. If this is the first time, meaning your RM4100 still has the original BIOS, you need to use the method on the RM4100 Customizing website to flash, otherwise you can just use flashrom.
