I guess I'm stuck during hardware probe or + it panics. + x 2.0 seems to react the same way as 1.3.1. + - knoppix + x 2003-07-13_4 boots but does not detect the hardware the right way: + it wants to use the VESA driver for X. If you are patient, + after a few tries, it will fallback to fbdev driver. + But then, the mouse is broken (uses the Microsoft serial protocol) + and the keyboard is set to german. + x k-mib-ppc-beta uses 2.6 kernel. + - gnoppix hoary boots kernel 2.6, then framebuffer is buggy + (colors are broken: should detect 15 bpp fb, but uses 16 bpp). + - sysrescue boots kernel 2.6 so framebuffer is buggy + (no output but the penguin). + - Fedora Core 3 uses 2.6 kernel then ... + ... seems to stay stuck into a small infinite loop inside the kernel. + - Fedora Core 4 does the same. + - unbuntu does not load: we don't find any bootable file on the HFS partition. + - yellow dog 4.0 boots with 2.6 kernel. + - rock linux: it boots and installs. Unfortunatelly, there seem to be some + bugs in this distribution: I did select the minimal installation, + then it forgot the "hfsutils" package and so yaboot did not install itself. +* NetBSD: + - 1.5.2 fails to boot. + - 1.6.1, 1.6.2 & 2.0 boot-loader loads but stops + (missing available memory property). +* OpenBSD: + - boot-loader cannot run because it's a gzipped ELF file. + (tried 3.4, 3.5 & 3.6 macppc CDROMs). +* Darwin: + - Darwin 7.01 and gnuDarwin 2.3 beta dont run: boot-loader crashes: + seems to rely on special values in registers (or entry point is false...). + looks like Mach-O embedded in XCOFF (?). + - Darwin 6.02 and OpenDarwin 6.6.1, 6.6.2 & 20030212 load + but seem not to like the OF tree as it's shown then crash. + - Darwin 1.41, MacOS X 10.2 & gnuDarwin 2.3 boot + but fail to mount the boot device. Seems related to the OF tree. + - gnuDarwin 7.01 does not boot at all (cannot find the boot file). + - OpenDarwin 7.2.1 does not boot (no boot partition found). +* MacOS: + - Mac OS X 10.2: fails to mount its root device. + - Mac OS X 10.3 crashes: + seems to try to use Altivec instructions.

I don't even know if they would run on a real PREP ;-) + +CHRP emulation: + TODO (no support in qemu). + +MVME emulation: + TODO (no support in qemu). + +Pegasos emulation: + TODO (no support in qemu). + +=============================================================================== + +Known problems: + +--- +RedHat make 3.79 is fully buggy. You may have several problems trying to build +OpenHackWare using it. You'd better update to make 3.80 or recompile it from +regular sources (ie not RedHat sources). Please don't complain if you aren't +able to build the BIOS using this package. + +=============================================================================== |
