heavybass Posted March 8, 2006 Share Posted March 8, 2006 Since OSX 10.4.3 the mach kernel uses PAE and my processor doesnt support that, i wondered if it is possible to build a kernel without PAE. I can build a linux kernel without PAE. And I think that the PAE should be transparent to applications. So a compiled app can run with a PAE enabled kernel and with PAE disabled kernels. So my questions is ( I dont know how the pae is realised), are the applications dependent on pae in darwin/os x or do they also run with a pae disabled kernel? If the apps are not dependent on PAE in the kernel, then one can build a kernel without pae. heavybass Link to comment https://www.insanelymac.com/forum/topic/11358-build-a-pae-disabled-kernel-from-darwin-sources/ Share on other sites More sharing options...
rApJtR Posted March 8, 2006 Share Posted March 8, 2006 I don't think it is possible, however I still hope some one is able to do that....because I have a Banais with PAE really broken.

valosx86 Posted March 8, 2006 Share Posted March 8, 2006 I manage to compile the xnu kernel from darwin without PAE... it boot under darwin, but when using it from osx it reboot ! don't know why, and don't know how to debug that !

doc Posted March 8, 2006 Share Posted March 8, 2006 I am pretty sure it is not possible to build a OSX kernel from the darwin sources . maxxuss said as much in some of his technical info.

Azurael Posted March 8, 2006 Share Posted March 8, 2006 What are you on about? You try telling the 1.4GHz Banias chip in the ThinkPad X31 I have 10.4.3, 10.4.4 and 10.4.5 booting just fine on... It also boots fine on a Celeron-M Banias, a couple of Dothan machines and numerous AMD machines I've been playing with it on. I thought the PAE problem with Pentium-M was fixed ages ago? Have you actually tried it? If so, it's probably a bios specific bug...

nascent Posted March 8, 2006 Share Posted March 8, 2006 I don't know for sure if it will work or not, but I say give it a try! You can build a custom kernel that works with Mac OS X from the Darwin sources. Here's a link on how to do it. http://developer.apple.com/documentation/D..._section_3.html As for disabling PAE, you'll have to figure that out yourself.
