What i did about Intel LinuxBIOS support 1. change ICH5 to ICH5R in v1. 2. move E7501 and ICH5R from V1 and V2.
For SB, documentation should be enough. For NB, I guess there is some undocumented info, and you may talk to intel directly or hack it out.

Maybe change to use AMD or other platform, or even PowerPC.
The architecture is fixed. I either have to find a way to make LinuxBIOS work with it, or switch to something else. Which comes back to my original question...is there any more information available on the undocumented things the LinuxBIOS E7501 code does? Does the LinuxBIOS community support this code, or recommend against using it?

and we can be pretty sure, based on Intel's comments w.r.t LinuxBIOS, that they will decline to help.

I'm interested in this too; I've hacked up a checkout from arch so it actually compiles for epia-m now, but I'm waiting for my BIOS Saviour to arrive before I can test it. It sounds like there are private trees floating around that have at least some extra work done on them though?

Jonathan I have a prom flasher and am more then willing to test the code. If you would tar/gzip your tree and send it to me I will compile it for my EPIA-MII and test it for you. The worst that could happen is the system does not boot at all, that why I bought the prom flasher in the first place. :-) Adam

Heh. Well, I make absolutely no guarantees about this code other than "it compiles for me". It won't do VGA stuff and having had a further prod around there's a lot of cleanup that needs done around the vt1211 code. I've no way of running it or testing it until my kit arrives and I'm loathe to start making more changes until I've tested at least this lot to see if anything happens. :)
However, I've put what I've got up in an Arch repository.

Where do I turn up the debug so I can get a bit more info and perhaps track the problem??
Try adding:
uses DEFAULT_CONSOLE_LOGLEVEL uses MAXIMUM_CONSOLE_LOGLEVEL
to src/mainboard/via/epia-m/Options.lb just under "uses OBJCOPY"
and then:
option DEFAULT_CONSOLE_LOGLEVEL=9 option MAXIMUM_CONSOLE_LOGLEVEL=9
to targets/via/epia-m/Config.filo.lb just under "option HAVE_FALLBACK_BOOT=1"
You'll need to do the ./buildtarget again afterwards obviously.

Also, I've just fixed up the config a bit more (and checked it into my arch tree) so the southbridge init stuff should actually get called - I don't think it was doing so before. Still looking at the right way to handle the vt1211 stuff.

Hmmm. I wonder if it's the fact the CONFIG_CONSOLE_SERIAL8250 option doesn't appear to get set; in fact I don't see any console option set by default.
Try adding "uses CONFIG_CONSOLE_SERIAL8250" to src/mainboard/via/epia-m/Options.lb under the LOGLEVEL bits you added, and then "option CONFIG_CONSOLE_SERIAL8250=1" to targets/via/epia-m/Config.filo.lb and see if that gives you some more output?

Slowly we seem to be making progress. :)
I /think/ the southbridge code needs some cleanup. It'll be a day or two before I have time to look properly, but if you shove
printk_debug("In VT8235 southbridge_enable\n");
in the southbridge_enable function in /src/southbridge/via/vt8235/vt8235.c that'll at least show if it ever gets that far. Don't worry if you don't have time though, as that whole area definitely looks like it needs work anyway.
The half baud rate problem is something I've seen mentioned before; something to do with the southbridge and various clocks settling down? I'll worry about it once other matters are sorted. ;)

Attached is the diffs file generated by 'tla changes --diffs'. For your convenience, I've also put a gzipped tarball at http://klassified.info/freebios2--tla33-epia.tar.gz but the host apparently takes forever to sync disks so it may not show up there just yet.

Great, thanks. Minor issue I found while using it as a basis for the EPIA-M stuff:
+static void ide_init(struct device *dev) +{
- struct southbridge_via_vt8231_config *conf;
- unsigned char enables;
- if (!conf->enable_native_ide) {
I think you want:
struct southbridge_via_vt8231_config *conf = dev->chip_info;
otherwise you're dereferencing an uninitialised pointer?
