Bochs Disk Images

These disk images are for use with the Bochs x86 Emulator. I am providing them to make it easier to get started with hacking Bochs. All of them were built and tested using Bochs 2.6.2 compiled with the following configure options: 

./configure \
  --enable-smp \
  --enable-x86-64 \
  --enable-all-optimizations \
  --enable-long-phy-address \
  --enable-configurable-msrs \
  --enable-disasm \
  --enable-fpu \
  --enable-alignment-check \
  --enable-3dnow \
  --enable-svm \
  --enable-vmx=2 \
  --enable-avx \
  --enable-a20-pin \
  --enable-pci \
  --enable-clgd54xx \
  --enable-voodoo \
  --enable-usb \
  --enable-usb-ohci \
  --enable-usb-xhci \
  --enable-cdrom \
  --enable-sb16 \
  --enable-es1370 \
  --enable-show-ips \
  --with-all-libs

Tiny Core Linux (CorePlus) 5.1 (32-bit)

Tiny Core Linux is a very small Linux distribution with a recent kernel (3.8.13). It is very good for testing hardware/kernel mods. See the project's Wiki for instructions on compiling a custom kernel .

Debian Wheezy (32-bit)

This is the current stable release of the Debian Linux distribution. No windowing system is installed, since that is too much for Bochs to handle. It just boots to a shell.
