Hello list, here's my actual config-file, but somehow the resulting linuxbios.rom is only 64 kB instead of 256 kB, although setting: "option ROM_SIZE=262144" Filling the Linuxbios.rom to 256 kB with zeros (dd if=/dev/zero bs=1k count=192 >> linuxbios.rom) or with itself three more times (cat linuxbios.rom linuxbios.rom linuxbios.rom linuxbios.rom > bios256.rom) doesn't work, the monitor displays nothing (is framebuffer neccessary for that?!). So, how to make the generated linuxbios.rom will be 256 kB? Thx, Tom target testawb651 mainboard ics-d/awb651 # Enable Serial Console for debugging option SERIAL_CONSOLE=1 option TTYS0_BAUD=38400 option VIDEO_CONSOLE=1 option DEFAULT_CONSOLE_LOGLEVEL=9 option DEBUG=1 # option HAVE_FRAMEBUFFER=1 option USE_GENERIC_ROM=1 option USE_ELF_BOOT=1 option ROM_SIZE=262144 option STD_FLASH=1 linux /stuff2/Linuxe/kernel2422 commandline root=/dev/hda1 console=ttyS0,115200 FS_MODE=ro hda=flash

Please try connecting a serial nullmodem cable and see if you get any output there. What graphics card does the system have? LinuxBIOS is unlikely to initialize your video correctly, except on a very small number of boards with onboard graphics (or with testbios) linuxbios.rom is only the linuxbios image without the payload it seems. I have in mind that V1 was not as solid with payload handling as V2 is, but I may be wrong..
okay, I've got a nullmodem-cable here, but how can I see if there is any output? my graphics-controller is integrated in the Cx5530A-chipset. I think it should be supported, or am I wrong? Thx, Tom Stefan Reinauer wrote:

Connect it to your LinuxBIOS machine on the one side, and to another machine running a terminal program on the other side (ie minicom or screen)

Someone here on the list got it working, but generally speaking, it does not work out of the box. Cx5530 has a pretty broken design.. Stefan

I did a quick and dirty port of LinuxBios V1 to an SBC with a GX1 CPU and a CS5530 using the cocom/voyager2 directory as a base and managed to get it up and running fairly quickly with console output on the serial port. Basic console graphics took a little longer (but not much) but unfortunately I then ran out of time before I got graphics working fully. If you want I can dig out the diffs and my config file and mail them to you but I should warn you it was a bit rough and ready so they would definitely need more work (and I don't really have time to pursue it myself right now). However a quick look at your config compared to mine shows a few lines which I have in mine which may be significant (or not): option ZKERNEL_START=0xfffc0000 option ZKERNEL_MASK=0xffff option PAYLOAD_SIZE=196608 Of course if you're using LinuxBios V2 then this won't be much use to you I'm afraid.

Right. Geode support has not been ported to V2 yet. And I doubt somebody will do it. Even though it is pretty straight forward.. V1 works fine though and V2 gives no immediate advantages over V1 on Geode at the moment Stefan
