[LinuxBIOS] question regarding build Options
by Ben Hewson 01 Sep '06

01 Sep '06

Ok after some playing around I have managed to get my EPIA board partly booting. I had commented out the fallback section in LinuxBIOSv2/targets/via/epia/Config.lb however the LinuxBIOSv2/src/mainboard/via/epia/Options.lb had uses USE_FALLBACK_IMAGE Anyway after booting I get the following LinuxBIOS-1.1.8.0Normal Fri Sep 1 22:07:37 BST 2006 starting... vt8601 init starting Slot 00 is SDRAM 04000000 bytes x2 Slot 01 is SDRAM 04000000 bytes x2 Slot 02 is empty Slot 03 is empty vt8601 done I have 2 x 128Mb DIMMS installed so I think they are being detected ok, however that is as far as things get. What I am trying to do, without much success is to enable the debug output. I guess I am missing the obvious, but how do I do it ? I assume I will need to modify LinuxBIOSv2/src/mainboard/via/epia/Options.lb Anyway any help would be much appreciated. Ben

[LinuxBIOS] Geode GX1/5530: How to forward SMI to a regular IRQ
by Juergen Beisert 01 Sep '06

Hi all, I try to write a native sound driver for the Geode GX1/5530a Companion chip. Problem here: The sound chip only generates SMI. Does anyone knows a trick or a chipset switch that let me forward this SMI to a regular IRQ? Its too ugly to use a polling loop.... ;-) Regards, Juergen

[LinuxBIOS] Enabling USB 2.0
by Anil B G 01 Sep '06

Hi, I am trying to enable USB on a board similar to Tyan s2892 (CK804) chipset? Is there anything that else that needs to be done separately other than setting the irqs et al correctly? Specifically do we need to write some sort of a driver to enable the USB host controller. Thanks Anil
