Aruba APs are mostly 3x3:2 (3 antennas, 3 transmit chains, but still only 2 spatial streams). In fact, most Cisco APs are 3x2:2 (3 antennas, 2 transmit chains, 2 spatial streams). It does not have an 'Extra' antenna for 802.11, that J3 antenna is hooked into the BCM2070 Bluetooth chip at the bottom of that wireless board, so it's a bluetooth antenna.Īpple is still ahead of the game with a 3x3:3 radio, as most APs (Even Cisco enterprise APs) do not support 3 spatial streams today. There could be more clarity around the wireless card. I understand that as delivered, the motherboard is designed to work with an optical drive on the optical drive port (3gb/s) & a SSD or HDD on the main 6gb port.ġ) Where's the actual quote of what David Moody said?ģ) Given that he is a hardware executive, is it reasonable that they did a hardware correction, (rather than a software patch)Ĥ) Can we trust that Intel's budget for the recall replaces for full HDD support on the optical drive Cleaver. : 'Earlier this year, Intel discovered problems in the chipset of Sandy Bridge processors that were shipping, but Apple vice president of worldwide Mac hardware marketing David Moody told Macworld that the company was using the latest updated versions, which corrected the flaw.'įrom. So I did some digging - the best assurance I can find is on. That link shows people have already fitted exiting OptiBay models. they've emailed to say they will know within a few days their official opinions. I've an outstanding request with MCE Technologies asking them to verify. I suppose that shifting the SSD to the OptiBay and adding a HDD would necessitate changing a PRAM / NVRAM setting.

The drive is considered user replaceable - such that users can swap either HDD for SSD or (less likely) SSD for HDD - meaning the motherboards must be identical and include the Sudden Motion Sensor. My conclusion / assumption on this is that the SSD models are all build-to-order vs, ready made for the HDDs. That said, I couldn't see a KXM chip on the teardown photos (but didn't find them on past models either.) , the MacBook Pro has in the past featured a Kionix three-axis accelerometer chip, (KXM52-1050), for protecting its HDD.
