== VGA vs. headless ==
== Hardware ==
 
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:
* Low Voltage Intel® Celeron® processor (Micro-FC-BGA) 733MHz
* Intel 830M northbridge
* Intel 82801DB (ICH4) southbridge
* SMSC LPC47M192 Super I/O
* ST M50FW080 8-Mbit (1Mbx8) Firmware Hub (FWH) flash memory
* 128MB PC133 SDRAM on board
* Two USB 2.0 ports
* 2 Ultra-ATA/100/66/33 IDE channels (no connectors)
* 64MB Compact Flash via IDE controller (upgradeable)
* Integrated 10/100 Intel 82562ET LAN On Motherboard (LOM)
* Integrated 2D and 3D graphics with AGP 4X interface
* Conexant CX25873-13 High Performance Video Encoder
* Optical SPDIF output (Dolby Digital)
* Composite and S-Video outputs (can deliver either NTSC or PAL video)
* Integrated Conexant CX81801-94 SmartV.XX V.92, V.34, V.32 data modem
* IR receiver for remote / keyboard
* 3 LEDs with GPIO control


Edit '''targets/rca/rm4100/Config.lb''' and change:
== VGA vs. Headless ==


# option ROM_SIZE = 1024 * 1024
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.
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 ===
See [[VGA support]] for information on how to add support for the onboard VGA controller.
 
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''').

Now we are ready to build coreboot.
Now we are ready to build coreboot.


$ cd ~/coreboot-v2/targets
See the [[Build HOWTO]] for information on how to build coreboot for this board.
$ ./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
See [[VGA support]] for information on how to add support for the onboard VGA controller.

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]].
