OSx86 on the OLPC XO Laptop

It may be a XO-1.5.

Thats right, you need atleast a SSE2 processor to run osx86.

I just got it in, its just a XO-1 but a very weird computer it is, It uses a AMD Geode processor, which(correct me if I am wrong) support SSE2 instruction sets. When I got it from a Goodwill thrift store, They messed up the Fedora linux based OS called "Sugar" that was on it I reinstalled and I am now currently awaiting a "Developer Key" that will disable this machines "DRM" feature allowing me to have full contol over it.

Its a nice laptop, I got my Dev. Key but what I cant figure out is that if it does support SSE2 then how will I coax it to boot, you see it uses Open Firmware (like the old PPC macs).

But these machines support the Fedora 10, which I assume needs a computer with atleaste SSE/SSE2?

intresting, I'll do some research and get back later, This would make an awsome Tiger machine, but as I said how in the world would Open Firmware boot an Intel based Tiger install?

This is what the readout is of the OLPC XO-1 is from the "cat /proc/cpuinfo" command.

Such one: http://de.wikipedia.org/wiki/OLPC_XO-1 ↗ ?

No way for OS X - the CPU doesn't support the necessary instruction sets.

@00010It may be a XO-1.5.

Well according to this page: wiki.lap top.org/go/XO_1.5_A1 this version uses a VIA C7-M CPU, which is fully x86 capable and even supports SSE3.

There has been some cool guy who managed it to get OSx86 running on a OQO e2 (which is using that CPU as well) - you can watch his video on youtube: http://www.youtube.com/watch?v=qSJM4r4PVuY ↗

Anyway I would expect, that a lot of Apps like iTunes and the PPC based stuff will crash, cause I allege that you would have to do kind of CPU-Opcode patching like it's necessary on AMD systems, but for with VIA Opcode...

Pretty neat computer anyway.

Goede is a K7 based CPU - so I guess it maybe won't even have SSE support. You can check with using "cat /proc/cpuinfo" but I feel you won't have luck with that one.

@00010Its a nice laptop, I got my Dev. Key but what I cant figure out is that if it does support SSE2 then how will I coax it to boot, you see it uses Open Firmware (like the old PPC macs).

Just use the command I wrote above on Fedora, it will show you wether your CPU supports SSE2 or not. You might need to run it as root. Try using sudo or su.

@00010But these machines support the Fedora 10, which I assume needs a computer with atleaste SSE/SSE2?

No - most Linux distributions have very minimal hardware requirements. See here - docs.fedora project.org/release-notes/f12/en-US/html/index.html#sect-Release_Notes-Hardware_Requirements - Fedora 12 has a 200Mhz Pentium Pro given as minimal requirement - but I would not wonder if the Kernel would even work on any at least i386 based CPU.
I personally cannot realy understand the philosophie behind this (I mean who's stuck using such hardware?!) and would prefer to use i686 optimized Linux system like Arch or Crux...
