etherboot problem..
by jmcdowell＠issisolutions.com 27 Feb '09

27 Feb '09

Before I get flamed, I know this is the coreboot discussion forum. Someone told me the other day that coreboot was the form of linuxbios, and my issue touches linux bios. If this is the wrong list, please forgive me without burning me at the steak. Anyway, on with it. I have a problem, that has had me banging my head against the wall for weeks. I am finally giving up, and asking on the list, as I cannot find documentation to aid in fixing this issue. Here goes.. I have an Linux NetworX cluster here, that uses etherboot on the nodes. The new software replacement doesn't use etherboot, although it's capable of sending out the pxe payload re-packaged for etherboot. The problem is, that when it gets to loading the kernel, it just hangs there. So after trying to build all sorts of new newer newest kernels. I did a little home work. What I did find, was that execute "file" on each kernel. ( The new and old LNXI kernel ) did show two differences. Old : x86 boot sector My newly built kernels show something different. New : Linux kernel x86 boot executable RO-rootFS, root_dev 0x802, swap_dev 0x1, Normal VGA I have searched and searched for documents that explain how to get the image I need. Can anyone please shed some light on this issue? Thanks in advance. Joshua

Just an update / search for more clues.. I copied over a 2.4 .config file this time, and did a make oldconfig and with your console commands added to the append statement.

v2 HAVE_OPTION_TABLE patch
by Myles Watson 27 Feb '09

27 Feb '09

This patch makes several CMOS variable reads dependent on whether there's a table to read. Otherwise you never know what you'll get from the factory BIOS. There are probably more, but these are the ones compiled into the s2895. Signed-off-by: Myles Watson <mylesgw(a)gmail.com> Thanks, Myles

I tried adding those commands to the append section of the mkelf script and I still get the same thing.. I may not have mentioned it before. But I am watching these nodes over conman, as they have no video. If I use a lnxi built kernel, it will get past the firmware type message and eventually die because its not configured correctly. Which is ok, one I figure out how to get a working 2.6 kernel everytime, I wi address the other issues. I am convinced the kernel has issues. But I have even cped the .config of one of the earlier kernels and did a make oldconfig, built it, and still no change.

No it does not, I built one that doesn't have vga support and am not having any luck there. ------Original Message------ From: ron minnich To: jmcdowell(a)issisolutions.com Cc: coreboot(a)coreboot.org Sent: Feb 27, 2009 2:26 PM Subject: Re: [coreboot] etherboot problem.. your new kernel uses vga.

[PATCH] badram filtering
by Robert Millan 27 Feb '09

27 Feb '09

Hi, This patch implements badram filtering in GRUB. It's the same idea as in http://rick.vanrein.org/linux/badram/ but applied to GRUB. The badram module sits between loaders (or other users like lsmmap) and filters the mmap entries, but only when user previously set the "badram" variable (whose syntax is the same as the one in badram patch for Linux). NOTE this won't affect loadees that get the memory map from BIOS instead of from GRUB. This means it currently works for Multiboot and for the new/experimental Linux loader. -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and how) you may access your data; but nobody's threatening your freedom: we still allow you to remove your data and not access it at all."

Author: myles Date: 2009-02-27 18:51:16 +0100 (Fri, 27 Feb 2009) New Revision: 3959 Modified: trunk/coreboot-v2/src/cpu/amd/dualcore/dualcore.c trunk/coreboot-v2/src/cpu/amd/model_fxx/init_cpus.c trunk/coreboot-v2/src/northbridge/amd/amdk8/coherent_ht.c trunk/coreboot-v2/src/northbridge/amd/amdk8/raminit.c Log: This patch makes several CMOS/NVRAM reads dependent on whether there's a table to read. Otherwise you never know what you'll get from the factory BIOS. There are probably more, but these are the ones compiled into the s2895.
