[Barrelfish-users] Booting Barrelfish using TFTP - GRUB issues

[Georgios Varisteas]

Hey Shawn,

Actually it is not really a patch. GRUB supports network booting, although it is not part of its default compile configuration. You need to run '# configure --netboot' followed by more arguments that enable support for specific NICs. It is not recommended to just enable them all though. More on this in the README found in the netboot subfolder of the GRUB's tree. Also keep in mind that GRUB legacy is rather old code and wont compile with modern versions of GCC. Version 3.x is recommended but it might work with some early 4.x.

Apart from this you do need a patch to enable support for a 64-bit kernel but it has nothing to do with PXE.

Hope this helps

regards,
Georgios

Hey all,

I am trying to boot Barrelfish over a TFTP server but I am having trouble with GRUB. From what I understand, I need GRUB Legacy (0.97) with a patch for PXE. From here, GRUB would chain-load Elver, and then Elver would boot Barrelfish. (Correct me if I am mistaken on this)  However, I cannot get a patched version of GRUB 0.97 to install correctly to my hard drive. Has anyone gotten this method to work? If so, what was your environment and GRUB patches do you use?

Thanks,
Shawn
