Back when I was making PReP boot CD's with a perl script, Troy Benjegerdes was already making the changes to mkhybrid to handle PReP boot. I submitted his changes to the mkhybrid maintainer and recall him commenting that HFS/PReP hybrid boot CD's worked fine. I have high hopes too. :) The HFS partition isn't at block 0 on the media is it? That's where the PReP header (which is merely a PC partition table) sits. PReP firmware reads the first two 512 byte blocks on the media, looks up an entry in that header which contains an absolute offset to the start of an image, and then reads it in and vectors to it. > All of that is still theoretical right now, however. > What I can say for sure is: > > -rw-rw-r-- 1 dan Debian 756228096 Mar 21 17:26 potato-powerpc-1.raw > -rw-rw-r-- 1 dan Debian 680079360 Mar 21 17:27 potato-powerpc-2.raw > -rw-rw-r-- 1 dan Debian 162017280 Mar 21 17:28 potato-powerpc-3.raw > > Obviously I need to cut the size limits a little lower, but otherwise, we're > making real progress here :) I can confirm that some of my old bootable PReP CD builds really did work save for the insanity of all the broken packages and broken task selection in boot-floppies 3-4 months. There is some guy running around the Phoenix LUG with a Motorola Powerstack (PReP) that was installed from a pre-alpha potato/PowerPC CD. :) -- Matt Porter [EMAIL PROTECTED]
