In future realases, the build process will be more modular.
Because of that you will need to execute this step first.
(Needed if the next step fails...)

Change into source directory:
# cd $VMX_BASE/src
# make CPU=PENTIUM2
Change into build directory:
# cd $VMX_BASE/src/build/i386
Build project:
# make

Install:

# cp vmx /boot
Become super user:
# su
Enter password
# vi /boot/grub/menu.lst
(press i for insert)
Paste the following text at the end of the file:
