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.
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) ===
See [[VGA support]] for information on how to add support for the onboard VGA controller.
 
You have the ability to build a "headless" version of coreboot that will only output to the serial console:
 
Edit '''targets/thomson/ip1000/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
 
=== VGA ===
 
If you do want VGA you can choose how much memory is pre-allocated for VGA. Note: You can still use the serial console when VGA is enabled. 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/thomson/ip1000/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''').
