Freebsd on mac mini g4

I hope this will be your case as well.. I used to use hd:3,ofwboot. Ok, Thanks.

I probably won't get to this till this weekend, but I'll let you know. I just wanted to follow up on this. I tried all suggestions from daemonfowl and even a few I missed in the install text and still no boot. I even reinstalled at which point I noticed a message after the successful install message which says that you need to copy ofwboot to the HD using Mac OS. I wondering, is this the problem? And if so, should this not be a pre-install message?

OpenBSD has facilitated the macppc installation as though it be on i I bet that's what you want too.. Please try again and maybe you won't even need to setenv boot-device on openfirmware a was my case last time with 5. Last edited by daemonfowl; 9th April at PM. Hi all, just wanted to say that I had the same experience when I tried to put 5. I ended up just putting Tiger back on it for a few weeks, and then a couple days ago I re-read the macppc install file.

I went with MBR, and made the changes in ofwboot, and was able to properly replace the old Tiger with the new 5. All times are GMT. The time now is AM. User Name. Remember Me? Mark Forums Read. Donate to FreeBSD.

As with the port itself, these pages are still a work in progress. That means it is not being fully supported by our security officer, release engineers and toolchain maintainers. The easy way to use ports on FreeBSD is to use portsnap. Refer to the Handbook if you need assistance to use the Ports Collection. The powerpc64 port provides a bit kernel and userland, and is supported on all bit CPUs.

For those users with a choice, powerpc64 provides some additional features the ability to use more than 2 GB of RAM and ZFS support while having slightly worse ports support due to being a newer and less common architecture. Peter Grehan is the project leader.

There the real boot begins Libraries are initialized, some of them fail at the very moment eg. It loads the AROS executables and relocates properly. The kernel is loaded somewhere within first 16MB of RAM and then relocated to the virtual address at the very top of the bit address space. It puts all read-only sections upwards from the kernel base, and all writable sections downwards from the kernel base. This memory few megabytes will be used as a local pool for kernel and will be excluded from usermode access of any kind. The structure of an AROS kernel has changed to be a minimal kernel.

The loader typically GRUB can optionally get whatever modules libraries, resources, devices, etc into memory and make them available to exec when it starts. The only port that use to not do this was Linux hosted. UNIX-hosted kernel refactor.

OpenBSD on a PowerBook G4: A brief overview

Obtain libc interface later, after hostib. This allows to get rid of some duplicating code. Decreased number of global variables, no more global HostIFace needed. Got rid of many global KernelBase references, use getKernelBase instead. The handler calls back into UnixIO after the last write is done to disable write events.

UnixIO isn't reentrant, and so the lists got corrupted. Hosted uses the OS threading system to implement a minimal virtual machine, all within kernel. The other thing it does is neatly split modules into host-side and AROS-side parts. The AROS parts are handled as normal modules, but in their initialisation they call into hostlib. These are standard shared libraries which can bring in any library dependencies they need, neatly avoiding the problem contained within the X11 and SDL drivers in that its kinda painful to find the needed libraries at runtime.

This way, you just find what you need at link time. The idea is that there is still too much arch-specific code in exec. Adding a host. The next thing to do is reimplement task switching and interrupt core. After that hook DOS up and get something interesting happening.

That said, there is issue of which stdio. Possibly explains the segment violation error on executing existing ppc binaries from April build which never successfully opens files, loads kernel modules and beyond "bus error":. Bus error. This way the modules try to read the SysBase from that address. Since at the stage where this symbol is resolved, there is no other AROS component working. Therefore we can neither put there address of some other SysBase pointer there is none nor do anything else than using just some arbitrary position in memory.

So can't we use another absolute address other than 4 on PPC, one that does not fall in the first memory page? Let boot code then setup this virtual address to contain SysBase pointer? Used to generalize existing code. Howewer, soon after introduced krnAllocXXX primitive so that slab allocator would be used for these thing instead of exec's chunk allocator.

This was done because PPC kernels have own memory area, accessible only in supervisor mode, for these things. First, our KrnCreateContext could accept extra argument, holding initialization taglist. Currently exec. After this, we could have a single function, which can be replaced on per-implementation basis.

A generic implementation would call AllocMem , then set up fields. Another implementation could do own things.

Additionally we could get rid of one more supervisor more call exec's context initializer also has to become supervisor in order to access that memory. After attempts to use configure and various config files to generate makefiles in a graceful build approach, and having the config break on missing tools or failure to navigate the source code tree, found possible solution by copying.
