DirectHW is a software compatibility layer for Mac OS X. It provides a kernel driver and framework that emulates the most commonly used hardware access functions on x86 machines, such as:

  • iopl
  • inb, inw, inl, outb, outw, outl
  • rdmsr, wrmsr
  • mmap() of physical address space

This package was originally intended to get coreboot utilities running on Mac OS X. You're encouraged to use it for many more opportunities.

Note: Intel Mac required.

DirectHW is free software and released under the license ISC-L.
