Install the following package through Synaptic Package Manager:
bochs
bochsbios
bochs-x
vgabios
By default, when you mark bochs to install, bochsbios, bochs-wx and vgabios will be marked automatically. But you'd better to unmark bochs-wx and mark bochs-x.
After successfully installed those packages, edit the bochsrc file which is used as the configuration file for bochs.
In this file, set the vgaromimage to the bin file you installed, on my computer it is :
vgaromimage: file="/usr/share/vgabios/vgabios.bin"
When set cpu, I don't know why I can not set reset-on-triple-fault. Every time when I set it, it cause the bochs to fail, and after I remove it, the bochs can launch successfully. So I just delete it from the original configure file.
