GRUB doesn't look for an OF variable named debug (technically such a thing does not exist, according to IEEE1275), but rather a commandline argument. So you would do this: 0 boot debug=all or even 0 boot floppy debug=all ... but in this particular case, the crash is very very early, and also we already got our helpful debugging message. 0 boot Failed to claim heap at 0x4000, len 0x1fb000 This is telling us that GRUB attempted to claim some memory for its heap (at that address and that length), but some of it was already in use, so the request failed. From the OF prompt, before you boot GRUB, could you do the following and send the output: 0 dev /[EMAIL PROTECTED] 0 .properties In particular, the available property is the one I'm interested in.

mkfs command in grub
Can someone please comment if adding filesystem creation support to grub is reasonable. Please see the rationale at http://www.geocities.com/technologypages/grub-mkfs.txt Will the developers consider adding this feature? It is rather easy to implement as far as I can see -- only glue for external filesystem creation code needs to be added. Although the swap sharing use case discussed in the rationale is trivial, it is a common problem that may bring many multi-OS users over to GRUB 2 and create positive media coverage (if that feature will be added). ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
Re: Status of UNDI Support
I am resending this mail, it looks that it didn't get through: Martin Vogt wrote: Hello grub2 developers, I just tried pxegrub2, but I found out that the network support is missing. (can load pxegrub, but no menu.lst or kernel etc) hi, i have been working on netboot support for grub2 for a while and even got it working once using code from etherboot. I am now grubifying the work in order to submit a patch. The PCI support is on its way and is going to feature an abstract interface which should ease the merging of new implementations. My experience with grub1 and the etherboot based nic support, is that it does not work well, so I still use pxelinux. I always thought that grub2 wont use etheboot and only supports UNDI, like pxelinux. As far as I know, a lot of problems related to netboot in grub were linked to the fact that the drivers could not easily be linked together as it could result in grub freezing of behaving improperly. The idea in grub2 is still to use the etherboot drivers but not to be limited by them. There will be a glue layer in order to import the etherboot drivers, hopefully with as little modifications as possible, but it will be possible to extend that. Isnt it possible to re-use some UNDI support from pxelinux and put it into grub2? I don't know very much about this UNDI support but this is certainly not incompatible with using the etherboot drivers for supported cards anyway. Grub is very flexible and we can certainly have both support if it is worth it. regards, Martin -- Vincent Guffens Intelligent Systems Networks Group Research associate, Imperial College ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

Hi Marco, thanks for your reply. I read a bit grub2-devel and found out that there are some thoughts about linuxbios support. I dont know if linuxbios has some abstraction for network access. Usually (clusterenvironment) you get linuxbios with the right etherboot prom installed. The normal way for installing is booting an .ebi installer. The other way which somtimes is used, you go over pxe to the right etherboot image and then load an ebi. Only as an idea: It would be great if one grub binary could work on then UNDI layer and the etherboot layer (if there is any). But I dont know if this is possible at all. regards, Martin ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

Looking at the sources of pxelinux, it seems somewhat more complex than what you can tell from reading the specs, mainly because you want, as reasonably as possible, to support also buggy PXE stacks etc. So while it's probably not that hard, it would make sense to look at pxelinux for reference if not for the code. I personally was a user of both etherboot, grub with etherboot drivers and grub with undi (which indeed did not work well for me back then - I did not try it recently), and I agree it would make more sense for grub2 to support undi only, unlike grub legacy which tried to support everything etherboot supported, which was probably too much synchronization work and therefore did not work well. -- Didi ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

I prefer to support both. The etherboot drivers usually work better than UNDI, AFAIK. But when etherboot does not support a card, people can fall back to UNDI.
