BIOS Beep Codes When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected. Because there are many brands of BIOS, there are no standard beep codes for every BIOS. The two most-used brands are AMI (American Megatrends International) and Phoenix. Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems. AMI Beep Codes Beep Code Meaning 1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard. 2 beeps Memory parity error. The parity circuit is...

This reg file automatically ends tasks and timeouts that prevent programs from shutting down and clears the Paging File on Exit. 1. Copy the following (everything in the box) into notepad.

NOTE: If your anti-virus software warns you of a "malicious" script, this is normal if you have "Script Safe" or similar technology enabled.

Introduction This paper assumes a working knowledge of basic shellcoding techniques, and x86 assembly, I will not rehash these in this paper.  I hope to teach you some of the lesser known shellcoding techniques that I have picked up, which will allow you to write smaller and better shellcodes.  I do not claim to have invented any of these techniques, except for the one that uses the div instruction. The multiplicity of mul This technique was originally developed by Sorbo of darkircop.net.  The mul instruction may, on the surface, seem mundane, and it's purpose obvious.  However, when faced with the difficult challenge of shrinking your shellcode, it proves to be quite useful.  First some background information on the mul instruction itself. mul performs an unsigned multiply of two integers.  It takes only one operand, the other is implicitly specified by the %eax register.  So, a  common mul instruction might look something like this: mo...

----------- STARTUP ----------- Windows Prefetcher ****************** [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ PrefetchParameters] Under this key there is a setting called EnablePrefetcher, the default setting of which is 3. Increasing this number to 5 gives the prefetcher system more system resources to prefetch application data for faster load times. Depending on the number of boot processes you run on your computer, you may get benefits from settings up to 9. However, I do not have any substantive research data on settings above 5 so I cannot verify the benefits of a higher setting. This setting also may effect the loading times of your most frequently launched applications. This setting will not take effect until after you reboot your system. Master File Table Zone Reservation ********************************** [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ FileSystem] Under this key there is a...
