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 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 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 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 Share on other sites More sharing options...
