Hi, Someone asked me how to disable PAE mode on Solaris 10 x86.
I have done following testing before answer his question: 1. Setting "force_pae_off" option in /etc/system, and reboot system: vi /etc/system .... set force_pae_off=1 2. Checking %cr4 register with kmdb -bash-3.00# mdb -K Welcome to kmdb Loaded modules: [ crypto ptm ufs unix krtld sppp nca lofs genunix ip logindmux usba specfs nfs random sctp ] [0]> ::status debugging live kernel (32-bit) on boltx-1 operating system: 5.10 Generic_118844-26 (i86pc) CPU-specific support: AMD DTrace state: inactive stopped on: debugger entry trap [0]> force_pae_off/X force_pae_off: force_pae_off: 1 [0]> getcr4::call 6f8 = getcr4(); [0]> According to manual of x86 cpu, if PAE mod is disabled, the value should be "6d8", I don't know what's wrong with my testing. Does anyone can tell me?
