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.
