-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, I just found that if I disable "AES NI" in BIOS setting, FreeBSD would be able to detect it on boot with: Features2=0x29ee3ff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,<b17>,DCA,SSE4.1,SSE4.2,POPCNT,AESNI> However if it's set to "enabled" I got: Features2=0x9ee3fd<SSE3,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,<b17>,DCA,SSE4.1,SSE4.2,POPCNT> The CPU was Xeon L5630 and motherboard is Supermicro X8STi with BIOS 1.00c. Should I consider this a BIOS issue with known workaround that I consider "Disable" as "Enabled"? :) Cheers, - -- Xin LI <delphij@delphij.net> http://www.delphij.net/ FreeBSD - The Power to Serve!
