Booted it again with '-p', and discovered quite a few things : [ 0.000000] PROMLIB: Sun IEEE Boot Prom 'OBP 3.30.0 2003/11/11 10:37' [ 0.000000] PROMLIB: Root node compatible: sun4u [ 0.000000] Linux version 2.6.18-rc2 (maz@positive) (gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)) #15 SMP Mon Jul 17 11:44:17 CEST 2006 [ 0.000000] ARCH: SUN4U [ 0.000000] Ethernet address: 08:00:20:d8:e4:6d Remapping the kernel... done.
