When IBM is ready we'll hear from them. Until > thentrying to push would only have negative results Hi, I'm one of the guys working with grub2 at IBM. That's my first mail to = the=20 list :) The default bootloader for PPC machines is still Yaboot (at least on RHEL a= nd=20 SLES), and our main goal here at IBM is to contribute code to grub2 to make= it=20 Yaboot's replacement for PPC systems (specifically IBM POWER5, POWER6 and P= OWER7=20 machines). The most important feature that we were lacking in grub2, from a PPC=20 perspective, was netboot. We ported bootp/tftp support from yaboot to grub2= , but=20 the implementation was PPC specific, relying upon OFW's obp-tftp package to= =20 handle all network communication. We discussed that with Vladimir, who pointed out the following drawbacks: 1) Current implementation was BOOTP/TFTP only. No support for other protoco= ls. 2) Almost no shared code between architectures. 3) 100% dependent on OFW. We are now working on a network infrastructure that could be shared by all= =20 platforms, including protocols, device drivers, etc. Gpxe project is a good= =20 start point, and most of things are being developed based on it. Chances are that we'll have something working on x86 soon, and then we'll s= tart=20 adding support for PPC (access to PCI bus via OFW, VIO, device drivers for = some=20 very specific cards like ehea, etc). So far Manoel Abranches is the only person (part-time) actually developing = code=20 and he's doing that based on the skeletons created by Vladimir (am still ge= tting=20 some approvals from IBM legal to contribute code...).
