"Welcome to the new plex86 web site. I have rehashed/revitalized the previous plex86 architecture to offer a very lightweight Virtual Machine (VM) for x86."
a386"a386 is a C programming library which provides a virtual machine. The virtual machine is an abstraction of an Intel 386 running in protected mode. Functions in the library corresponds to privileged processor instructions and access to hardware. The intended use for the library is to serve as a minimal hardware abstraction layer for operating system research."
Bochs"Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms."
Qemu"QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed."
PearPC"PearPC is an architecture-independent PowerPC platform emulator capable of running most PowerPC operating systems."
