DrvLoad
PC Magazine, November 9, 1993
MS-DOS
application that allows device drivers to be loaded from the DOS
prompt. Completely emulates DOS's own driver loading logic. Manipulates
undocumented system data structures and transparently adds drivers
to system.

Your Own Protected-mode
Debugger
Dr. Dobb's Journal, September 1992
Written
entirely in 80386 assembly language, this is a complete working
implementation of a protected-mode debugger. Sets up a virtual machine
monitor and runs MS-DOS in virtual 8086 mode. Allows breakpoints
to be set on I/O accesses, data accesses, interrupts, and code execution
(even in ROM). Can coexist with, and enhance, other debuggers such
as CodeView.
