pxebooting with GRUB 2
Hi folks-- I've searched high and low for documentation about how to get PXE booting working with GRUB 2, but i haven't had much luck. Can anyone give me pointers? What i've done so far - I found a brief mention on the wiki [0] and followed those instructions: "cat pxeboot.img core.img >pxegrub" does create a PXE-bootable grub image, but once the image is loaded, GRUB 2 doesn't seem to be capable of downloading other files over the network (this includes being unable to download its own config file). I get dropped into a "rescue GRUB shell", which appears to be only useful for pulling files off of a local disk -- but that sort of defeats the purpose. Here's what i see on the screen after the pxe boot: Welcome to GRUB! Entering into rescue mode... grub rescue> looking at the logs of my TFTP and DHCP servers, i see the initial (boot ROM-generated) PXE interaction of a DHCPDISCOVER/OFFER/REQUEST/ACK handshake, and the initial TFTP download of the pxegrub file itself, and then nothing. What else do i need to to enable pulling files via TFTP? i've successfully pulled files off a TFTP server with a patched GRUB Legacy [1], but i'd like to support and use GRUB 2 if possible. Details --- FWIW, the above attempt was done using a Via Rhine NIC with functional PXE boot ROM. the version of GRUB 2 that i tried is the one in debian unstable at the moment (1.95+20070828-2), and i was using the core.img generated on this same debian unstable system that initially boots from a local disk. Maybe i need to regenerate a different core.img somehow? Final Questions --- Is there documentation somewhere that i missed? I'd love to get a pointer or two if it's out there. I'm also happy to help debug this, and to write up my notes on the wiki, if folks think that'd be useful. What next steps should i take to get network booting working? Do you have any advice? Thanks for making this useful tool, and for making it free.

Any pointers at all? even "this isn't a priority; don't bother trying" would be appreciated so i don't waste any more time. i've seen many links to this: http://www.inma.ucl.ac.be/~guffens/grub2_netboot/index.html but the page appears to be dead, and the wayback machine provides text, but no graphics or tarballs to download: http://web.archive.org/web/20061210001116/http://www.inma.ucl.ac.be/~guffens/grub2_netboot/index.html Thanks for this great tool, --dkg pgpicQwYzXGil.pgp Description: PGP signature ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
RE: pxebooting with GRUB 2
Hello! To be honest I wasn't aware that anyone did do all of that. According to the other list members they want to accommodate the abillities of GRUB2 to be able to boot an operating system on other platforms, and then the concepts of network booting which was accomplished on the original GRUB-Legacy system. Is there a reason why you've not tried a network boot using GRUB-Legacy? Or are you not working on an X86 based platform? -- Gregg C Levine [EMAIL PROTECTED] "The Force will be with you. Always."

Or are you not working on an X86 based platform? Perhaps i've been confused by the idea of what "grub legacy" means. Yes, i've tried and succeeded at pxebooting with a patched version of GRUB-legacy [0], but i thought i understood that new features/patches weren't being accepted into GRUB Legacy. In particular, i was hoping to see a pxe-capable grub or grub2 packaged cleanly for my distro of choice (debian), but interpreted a comment by Robert Millan [1] to imply that GRUB2 netbooting or PXEbooting was superior and better-supported in GRUB2. I probably didn't understand the context of his remarks well. I suppose i should go back to pushing for in-distro GRUB-Legacy PXE-booting support, if it's not a priority for GRUB2. I definitely like the idea of GRUB working on other platforms too, and i don't want to distract from that goal. Thanks for the help, the information, and the software.

Are you referring to this, from two months ago? http://lists.gnu.org/archive/html/grub-devel/2007-08/msg00011.html I couldn't find a more recent e-mail. And though the message suggests that the patchset will be in CVS within a week (i.e. mid-August), it doesn't look merged to me. i'm looking at CVS HEAD, though -- is there another branch i should be trying? I'm not sure what feedback i can give as i'm not a grub developer, and there doesn't appear to be enough in the patch (e.g. no IPv4 support) to make it something i can test as an end user. Marco, can you give another status report on netbooting?

No, you are right. In the current state it will not be very useful. I will work on this after dealing with patches that were sent in, LinuxBIOS related work and ATA support. > Marco, can you give another status report on netbooting? This patch that will be committed soon will be the foundation of networking support. After that I will add IPv4, UDP, TFTP, etc. -- Marco ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
