CDBG and DBG are hardware debuggers designed for use on a x86 based PCI system. They include an extensive set of debug commands as well as a either a C or Forth interpreter to allow flexible scripting and interactive diagnostic development.

CDBG and DBG are DOS based application designed to run in a variety of OS configurations.  We've successfully used DBG in
bare DOS configurations
DOS with EMM386/HIMEM
Windows 3.1 DOS box
Windows 95/98 DOS box

Why doesn't DBG use a fancy Windows interface with dialog boxes and pop-up menus?  DBG needs to be able to run in a simple environment to help debug hardware.  The Windows family of operating systems may make the debug environment too fragile to use.  Speed is also a concern.  We've used DBG on PCs where the Pentium is running at about 2% of its normal speed - you just don't want to wait for Windows to boot when the computer is this slow.
