Dear LinuxBIOS readers! This is the automated build check service of LinuxBIOS. The developer "stepan" checked in revision 2719 to the LinuxBIOS source repository and caused the following changes: Change Log: This patch adds support for the Intel i82810 northbridge and various i82801xx southbridges, along with the Asus MEW-VM. With this, my machine attempts to boot linux, but does so very slowly and fails during the boot process, probably because of the irq tables.

Dear LinuxBIOS readers! This is the automated build check service of LinuxBIOS. The developer "uwe" checked in revision 2718 to the LinuxBIOS source repository and caused the following changes: Change Log: Add the AMD DB800 (AKA Salsa) mainboard. The DB800 is the AMD LX Reference Design Kit platform. For details see: http://www.amd.com/geodelxdb800 Signed-off-by: Marc Jones <marc.jones(a)amd.com> Acked-by: Uwe Hermann <uwe(a)hermann-uwe.de> Build Log: Compilation of arima:hdama is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2718&device=hdama&vendor=… Configuration of artecgroup:dbe61 is still broken Compilation of ibm:e325 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2718&device=e325&vendor=i… Compilation of ibm:e326 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2718&device=e326&vendor=i… Compilation of iei:juki-511p is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2718&device=juki-511p&ven… Compilation of iwill:dk8s2 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2718&device=dk8s2&vendor=… Compilation of iwill:dk8x is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2718&device=dk8x&vendor=i… If something broke during this checkin please be a pain in uwe's neck until the issue is fixed.

[LinuxBIOS] dmidecode & lspci for new MSI P35 Platinum (Rollercoaster)
by Bob CFC 12 Jun '07

12 Jun '07

I read a post on a forum asking people to run these commands and post the results here to support the LinuxBios project. dmidecode lspci -n lspci -v lspci -t I have the new MSI P35 Platinum, E6600 Core2Duo at stock speed, 8gb (4x2) DDR2 pc2-6400 cas5 at stock speed (OCZ2G8004GK), Overclocked BFG Geforce 8800GTS 320mb Single PATA drive on the Marvell chip and no SATA devices yet. Running Ubuntu 7.04 (Feisty Fawn) x86_64. Hope this helps. Just ask if there is anything else that you need. Bob, London
