bcobco Posted September 12, 2012 Share Posted September 12, 2012 hello! i was wondering if someone is capable of booting with this flag arch=x86_64, for full 64 bits with a legacy kernel. actually the only way i can start with a legacy kernel is with flags arch=i386 -force64 other thing makes panic when loading the first kext (?) thanks in advance Link to comment https://www.insanelymac.com/forum/topic/282743-legacy-kernel-and-archx86_64/ Share on other sites More sharing options...
Matt35 Posted September 12, 2012 Share Posted September 12, 2012 have you try to boot with : -f -v -x Link to comment https://www.insanelymac.com/forum/topic/282743-legacy-kernel-and-archx86_64/#findComment-1852253 Share on other sites More sharing options...
bcobco Posted September 12, 2012 Author Share Posted September 12, 2012 have you try to boot with : -f -v -x yeah of course i know those flags... the thing is that, like many others, startup panics when loading ACPI system (appleacpiplatform ioacpifamily iopcifamily) seems that 64 bits kernel space (arch=x86_64) is not possible with AMD its only possible 32 bits kernel space (arch=i386) enabling 64 bits user space (-force64) can someone confirm this? best regards Link to comment https://www.insanelymac.com/forum/topic/282743-legacy-kernel-and-archx86_64/#findComment-1852262 Share on other sites More sharing options...
Matt35 Posted September 12, 2012 Share Posted September 12, 2012 yeah, maybe because AMD is not made like Intel ! Link to comment https://www.insanelymac.com/forum/topic/282743-legacy-kernel-and-archx86_64/#findComment-1852263 Share on other sites More sharing options...

Matt35 Posted September 12, 2012 Share Posted September 12, 2012 It's not the same architecture ! Link to comment https://www.insanelymac.com/forum/topic/282743-legacy-kernel-and-archx86_64/#findComment-1852268 Share on other sites More sharing options...
