== Building a LinuxBIOS image ==
 
 
$ cd targets
 
$ ./buildtarget bcom/winnet100
 
$ cd bcom/winnet100/winnet100
 
$ LANG=C make
 
 
The '''LANG=C''' is only for those users (like me) that uses a localised system. Determining some include pathes fails in LB's build system, if the GCC answers in German...
 
 
== Using the hardware with a current kernel ==
 
 
The current 2.6.22/23 kernel does not know the CS5530 interrupt router. So it is impossible to let the kernel itself setup PCI's interrupt routing. Even if you provide the kernel with a valid interrupt routing table (PIRQ). No interrupts will work as the interrupt routing registers are still left at their reset values.
 
The small patch below solves this issue (it was rejected in mainline as it breaks various standard BIOS based Geode systems, as they were shipped with broken PIRQ tables [http://lkml.org/lkml/2006/11/24/47]).
 
 
Since kernel 2.6.23 Geode chipset access macros are now working as expected. Due to this, some chipset tweaks embedded in the kernel are working now. One of these tweaks setup the performance incrementor for a 233MHz CPU. This may fail on a 300MHz CPU now (additionally it depends on the SDRAM speed). The symptom of this failure is a freezing system after running a while (after warm up). Take a look into '''arch/i386/kernel/cpu/cyrix.c''', function '''set_cx86_inc()'''. Correct the setting to:
 
setCx86(CX86_PCR0, getCx86(CX86_PCR0) | 0x05);
 
when you run a 300MHz CPU.
 
 
== How to bring LinuxBIOS in ==
 
 
I was not successful to boot anything other than the software in the DoC to get some information about this board. It seems a very special BIOS as it only outputs "booting os" and nothing else. Then the splash screen comes up and the graphical environment starts.
 
One or two times I was successful to run an update of this firmware. Because the update process fails (the server it tries to connect to doesn't answer anymore), the console comes up. That's why I know they run a 2.4 kernel with an XFree86 3.x. Their software needs about one and a half minute to boot up and supports graphical resolutions up to XGA@64k colours and SXGA@256 colours.
 
 
With my own implementation (LinuxBIOSv2, Linux 2.6.2x kernel, Xorg 7.2) I boot this machine in about 10 seconds, then the xdm dialogue occures (its a terminal, not a workstation) and supports also SXGA@64k colours.
 
 
As is it hard to get a console on this system with the original software, I found no way to reprogram the boot flash in a running system. But it is very easy to disassemble the flash memory. Only 3 screws to unscrew at the reverse.
 
 
Pull the front panel to one side, the casing to the other. Done. You now have access to all relevant parts.

|}
 
 
To disassemble the PLCC32 boot flash ROM you need something with a hook. I'm using my SMD tweezer. Did I mention that you will need something to burn your flash?
 
 
== How to build a root filesystem ==
 
 
This question is easy to answer. Download the following archives:
 
 
* [http://www.pengutronix.de/software/geode/OSELAS.BSP-JB-GeoTerm-2.tgz Board Support Package (BSP)]
 
* [http://www.pengutronix.de/software/ptxdist/download/v1.0/ptxdist-1.0.0.tgz Build System]
 
* [http://www.pengutronix.de/software/ptxdist/download/v1.0/ptxdist-1.0.0-patches.tgz Patch package]
 
* [http://www.pengutronix.de/software/ptxdist/download/v1.0/ptxdist-1.0.0-projects.tgz Generic projects package]
 
* [http://www.pengutronix.de/oselas/toolchain/download/OSELAS.Toolchain-1.1.0.tar.bz2 Toolchain package]
 
 
Start with the BSP, extract it and read the quickstart in Documentation/GeoTerm-Quickstart.pdf. It will guide you through the steps that are required to:
 
 
* get a generic project build system,
 
* get a cross toolchain for the Geode GX1,
 
* configure the BSP and build it,
 
* bring this target up and running with LinusBIOS and GNU/Linux.
 
 
The BSP builds all parts to run this Geode GX1 system. This includes LinuxBIOS and the kernel and also userland with X to run as a terminal (not as host!).
 
 
Note: This BSP includes all required patches for the kernel. You won't need the patches below.
 
 
== Required patches ==
 
 
When you build your own kernel for this target you might need the following patches:
 
 
* This [http://www.pengutronix.de/software/ptxdist/temporary-src/references/geode-5530.patch patch] is needed to let Linux know the Cyrix 5530 interrupt router.
 
* This [http://www.pengutronix.de/software/ptxdist/temporary-src/references/setup_correct_chipset_access_functions.patch patch] is needed as someone has overoptimised chipset tweaks so the used access macros failed. This patch is required only for kernels up to 2.6.22. From Linux 2.6.23 on it's part of mainline.
