Bochs Emulator – Config & Build on Windows and OS X

Introduction Bochs is an x86 – x86-64 multiplatform emulator that provides emulation of CPU Instruction Fetching without using Hypervisor technologies like Intel’s VT-x and AMD-V. One of the benefits of emulation rather than virtualization is that you can execute instructions of old discontinued CPU structures in modern CPU or run Intel’s instructions on an AMD […]

Assembly Challenge : Jump to a non-relative address without using registers

During developing a dispatch table for some instructions in binaries, one of the challenging problem which I faced, was changing the registers state in a way that doesn’t affect the program flow! So it might seem simple at first glance but what makes it complex is that I can’t use relative jumps or relative calls […]

A first look at some aspects of Intel's "Vanderpool" initiative

A few hours ago, I was working on Intel VT-x which enables a hardware support for virtualization then I saw the following slides which gives me lots of information about Hypervisor instructions,VMM, Virtual machine control structure (VMCS) and other practical information. I don’t know about its author actually but I should give my thanks to […]
