frame has a pointer pointing to the previous stack frame. The more addresses we get to point to the stack,The more likely it will be to succeed.Why? If we have a pointer to our own stack, We can overwrite the address pointing to any value. -- [3.1-Example 1 Suppose we want to put 0x1234 into the register local 0 of frame 1, what we need to do is try to createFormat the string. The length is exactly at the position of the frame 0 FP, that is, 0x1234. At that position, we use the format string.Pu

Threadid = 57428 The excerpt is as follows: Three types of memory, such as the local memory and system memory of the video card, all of us know that the local memory of the video card is the memory of the video card, and the system memory is the memory card of the video card. What is the content of the AGP memory? In fact, it was because the memory of the video card was very small in the past. At that time, wh

cards need to work in this memory address. When this option is enabled, a memory address is reserved for the ISA card, and the system can only use 16 MB of memory. So, unless your ISA card needs to enable this option to work, you 'd better disable this option.10. AGP aperture size (MB) (AGP channel size)Options: 4, 8, 16, 32, 64,128,256This option allows you to specify the maximum amount of memory that can

Casual Internet development, people on the computer's performance requirements are also more and more high, Tan Xianka also can not meet people's life and entertainment requirements, so people think with dual graphics card instead of Tan Xianka to improve the performance of the computer, but the installation of dual graphics card is not so easy, the following will tell you how to properly install dual 　　The two-card installation steps are as follows: 1, open the computer mainframe box, pay att

The video card overclocking is usually to provide the core frequency. What are the ④ graphics interface types? The interface type of the video card is two kinds of AGP and pci-express. The speed of pci-express is faster than that of AGP, and

Overclocking is now usually used to improve the FSB method. The improvement of FSB may cause a series of related equipment working conditions to change, so in the overclocking we have to the whole system of the overclocking ability to consider comprehensively. The ① motherboard has a frequency to choose from. We know that the frequency is generated by the clock chip on the motherboard. The FSB of the motherboard is important for the success of Overclocking, and the transition frequencies such a

Compatibility between the video card and the motherboard It mainly depends on whether the AGP specification is compatible. Due to the downward compatibility of The AGP specification, there are not many problems with the

and locate the resource through the memory. GPU access (Local video memory) memory is very efficient, and some resources (such as RenderTarget, depth, template buffer) must be located locally (Local video memory. Due to the emergence of AGP, GPU can directly access some system memory, and the memory area of this subsystem is the so-called non-local video memory. Of course, this part of memory (memory) it cannot be used. Non-local video memory can onl

Let's take a look at a pⅱ266 example, the machine uses the popular AGP display card, installed 64MB SDRAM, then its real ability to use the amount of memory? First, the Windows operating system uses about 6~10MB memory to store its own modules; second, the second killer will have to count the
