stryder Posted November 22, 2005 Share Posted November 22, 2005 My setup reboots as soon as it tries to load from the kernel. I think I've figured it out. From Maxxuss's page: "PAE" stands for "Physical Address Extension" and allows your CPU to address more than 4 GB of pyhsical memory. It is enabled by Mac OS X's kernel; sorry no work-around for this. PAE is actually a quite old technology (first found in the Pentium Pro), so current Intel and AMD CPUs should have this feature. However, some issues, probably related to motherboards/chipsets/RAMs, might cause trouble with native (i.e. non-VMWare) installations - typically, you experience an instant reboot after the boot prompt in this case. This issue is currently under investigation. Note: Some users observed that their motherboard will allow PAE only if the NX feature is enabled or full 4 GB of RAM are installed. If your CPU supports NX/XD, make sure you use the original or my SSE2 kernel with NX enabled. I can't enable PAE on my board, so unless I have 4GB of RAM, it's disabled from what I can tell... That could be your problem, too... Link to comment Share on other sites More sharing options...

I'm installing this on a Sony VAIO laptop. GRX-500 1.5Ghz P4-M with 256MB RAM. I type in the right kernel with the -v extention. It goes up to like the 4th or 5th line and just reboots. There is nothing related to PAE in the bios, not sure how to enable/disable it. I guess will have to wait. Link to comment Share on other sites More sharing options...

Mine is the 505, and I would need the 505j to support NX. Link to comment Share on other sites More sharing options...
VaiOSX Posted November 22, 2005 Share Posted November 22, 2005 openSolaris is having the same problem with the PAE fonction. http://cvs.opensolaris.org/source/xref/on/...m/mach_i86mmu.c Search for PAE in this page. I will check in the mach_kernel of Darwin to see if it's possible to disable it (for unlucky CPU owner without the PAE support). Link to comment Share on other sites More sharing options...
Brywalker Posted November 22, 2005 Share Posted November 22, 2005 Ahh, same problem here on my 875p chipset with a Northwood 2.6. Link to comment Share on other sites More sharing options...
