 Forums >>  IDA Pro  >>  x86emu 16-bit emulation support

Topic created on: July 22, 2011 05:51 CDT by Pinczakko .

Hi guys, I've been inspecting x86emu plugin source code for a couple of days and I found that the emulation provided by the plugin focuses on 32-bit execution environment with PE and ELF binaries as its targets. Has anyone modified/developed 16-bit support into the plugin? I'm interested to discuss the modifications that's needed for 16-bit execution environment.

Thanks in advance.

Hi,

You can use the Bochs debugger plugin. If you can for instance paste your code in a Bochs disk image then you can trace it via IDA. Something along this: http://www.hexblog.com/?p=103

Thanks lallous. I have a quick look into the Bochs plugin but I'm not sure yet whether it could really help because I'm reversing a PCI expansion ROM which is loaded prior to masterboot record execution. I'm not sure if the Bochs plugin could emulate it. Nonetheless, the plugin source code should help tremendously.

It turns out Qemu + IDA Pro Remote GDB support is more usable.
