It is defective, unfortunately. Aside from the CPU, the LC630 hardware had good Linux driver support last time I tested it. It's a late model and performs better than some earlier macs (Linux and MacOS). BTW, some of those logic boards have two DRAM slots and these will accept 192 MB. My own LC630 has only one DRAM slot, with a 128 MB SIMM fitted, which is probably sufficient (depending on what you want to use it for). > The only information I'm finding on doing this is quite ancient > (http://www.mac.linux-m68k.org/docs/gettingstarted.php) and I was > wondering if someone had information on testing this with one of the > more modern kernels, rather than the really old etch kernel. > > If I do happen to have one of the defective batch what would my options > be, short of buying a full 68040?

Of course, if you have the skills and the time, there's always a way. The CPU flaw did not prevent Apple from implementing virtual memory in MacOS, for example. In theory, you could patch the kernel to work around the CPU erratum somehow, and thereby make use of a binary distro like Debian. Alternatively, again only in theory, you could cross-compile an entire distro from scratch, notwithstanding possible soft-float tool chain issues. IMHO the source distros for embedded targets are better suited to that kind of hacking. > That said a lot of the information I'm seeing is quite a few years or > even a decade out of date. I agree. There is confusing historical information on www.mac.linux-m68k.org but I generally keep the FAQ and hardware compatibility information up-to-date. A refresh of the sf.net downloads and the pages relating to Debian has long been on my long to-do list. I don't really know what to do with Debian Hamm/Slink/Potato install guides at http://www.mac.linux-m68k.org/docs/ Can this stuff be archived on the Debian wiki? > > > Thanks very much, > > Hayden K. > > -- -- To UNSUBSCRIBE, email to debian-68k-requ...@lists.debian.org with a subject of "unsubscribe".
