The fault phenomenon is that when you enter a password on the connection, it will be disconnected after the connection, and it will be used normally after restarting, but it will not connect properly if you want to disconnect manually. Only reboot the first time into the system and normal. You cannot connect properly as long as you manually disconnect. Later try to install the IBM Access Co

The only difference between opt_calc and naive_calc is that opt_calc has two prefetch commands.
Below are the test functions in C language:

When the barrier () macro is not used and used in this diff.txt file, the compiler produces different assembly language commands:

After Ubuntu 12.04 32bit and win7 64bit are installed, win7 is basically no longer used. All work is done under Ubuntu. However, there is a problem: when running Ubuntu, the notebook is overheated.
Because the notebook is a dual-graphics card (hd5650 and Intel I5 480 integrated graphics card), it is suspected that the dual-graphics card swi
does not need to comply with the GPL. Many of Microsoft's APIs are not published, so that they can make better software than others.
Ii. x86 addressing
The emergence of 80386 marks a leap from 16-bit to 32-bit CPU. Its data bus and address bus are both 32-bit, and its addressing capability reaches 4 GB. To be compatible with the actual mode, Intel designers use the function of changing the segment register in the protection mode to point to a data st

The OLPC Organization's efforts to promote cheap laptops have been accepted by more and more companies. Walter Bender, former President of OLPC, is negotiating with four notebook manufacturers, including Intel, to promote Linux systems.The development prospects of the OLPC organization are unclear at the beginning of its birth. However, the XO cheap notebook launched by the Organization has recently become the focus of attention in the industry.Bend r

To install a system for an old desktop, a hard disk and an optical drive are inserted on a cable. As a result, the system cannot be started from the optical drive normally. Observe and find that:
On the same cord, you need to set the hard disk jumper to master, and the optical drive jumper to slave to show the difference.
After installing the system, remove the optical drive and restart the system. A series of "Intel boot agent" prompts are displa
