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/thomson/ip1000/Config.lb and change:
# option ROM_SIZE = 1024 * 1024 option ROM_SIZE = (1024 * 1024) - (64 * 1024)
option ROM_SIZE = 1024 * 1024 # option ROM_SIZE = (1024 * 1024) - (64 * 1024)
option CONFIG_CONSOLE_VGA = 1 option CONFIG_PCI_ROM_RUN = 1
option CONFIG_CONSOLE_VGA = 0 option CONFIG_PCI_ROM_RUN = 0
option CONFIG_VIDEO_MB = 8
option CONFIG_VIDEO_MB = 0
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
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).
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).
Now we are ready to build coreboot.
$ cd ~/coreboot-v2/targets $ ./buildtarget thomson/ip1000 $ cd thomson/ip1000/ip1000 $ 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/thomson/ip1000/ip1000 directory and then:
cat vga.rom coreboot.rom > cboot.rom
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.
