RE: [LinuxBIOS] Intel E7501 Northbridge head-scratching
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. YH

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. ron

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.

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?

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? J. -- 101 things you can't have too much of : 3 - Sleep. Ask me about server co-location - info@blackcatnetworks.co.uk
