So: - I have installed a Linux/Debian and I'm using GRUB2 to chainload the stage1 block in order to load the NetBSD kernel, using the booting once feature of GRUB2 so that if something goes wrong, I can go back to the Linux/Debian; - I have set (since I can see nothing of the boot process) a /boot.cfg with several choices, and set the default in order from the chainloading done by GRUB2 to try various things (since I haven't found the possibility to mount ffs rw under Linux, I use qemu-system-x86_64, under Debian, to write and modify the NetBSD partitions); - The machine is an Intel Xeon, quadcore, IvyBridge. Since the GENERIC kernel does not boot, I have compiled a custom 9.3, stripping all unneeded, and adding this feature (commented out in the GENERIC config): acpismbus* at acpi? # ACPI SMBus CMI (experimental) since from x86/pci/imcsmb/imc.c, there are some pecularities about the (Sandy,Ivy)bridge with the Xeon. Disabling the framebuffer (i915drmkms) via userconf, and disabling the SMP, NetBSD boots on the machine. The dmesg is here: http://downloads.kergis.com/misc/rpt_netbsd9.3_monocore_no-fb.dmesg Since I fought quite a lot with Debian, GRUB2 and so on for the installation and the boot process, I have to verify if an SMP version of the same does boot or not. If an SMP does not boot, I will go back to the list to have tips about how I can best gain informations about what's going wrong in order to try to fix or help to fix it. -- Thierry Laronde <tlaronde +AT+ polynum +dot+ com> http://www.kergis.com/ http://kertex.kergis.com/ http://www.sbfa.fr/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C
