So, they will not boot with the current common powerpc kernel, no ? Would it make sense for me to include the patches in the common powerpc kernel, or not ? And what do they use for booting, what filesystem ? What is in the /proc/cpuinfo machine field ? > The MVME5500 is a completely different beast (it should be > available now or soon), with a Marvell Galileo host bridge. Is this the one called GT-64130 or GT-64131 ? BTW, the next generation of Pegasos boards will use the Marvell Discovery II northbridge. Friendly, Sven Luther
