Cheat Engine Lazarus is designed for 32 and 64-bit versions of Windows 7. Cheat Engine is, with the exception of the kernel module, written in Object Pascal. Cheat Engine exposes an interface to its device driver with dbk32.dll, a wrapper that handles both loading and initializing the Cheat Engine driver and calling alternative Windows kernel ...
Under DOS, the kernel, drivers and applications typically run on ring 3 (however, this is exclusive to the case where protected-mode drivers or DOS extenders are used; as a real-mode OS, the system runs with effectively no protection), whereas 386 memory managers such as EMM386 run at ring 0.
A monolithic kernel is one single program that contains all of the code necessary to perform every kernel-related task. Every part which is to be accessed by most programs which cannot be put in a library is in the kernel space: Device drivers, scheduler, memory handling, file systems, and network stacks.
Unix, Linux, OS/2, Windows NT are considered modern OS's as they switch the CPU into protected mode at startup, never return to real mode and provide all of the benefits of protected mode all of the time. 64-bit operating systems use real mode only at startup stage, and the OS kernel will switch the CPU into long mode.

Historically, drivers were less of a problem, as the number of devices was small and trusted anyway, so having them in the kernel simplified the design and avoided potential performance problems. This led to the traditional driver-in-the-kernel style of Unix, [23] Linux, and Windows NT. With the proliferation of various kinds of peripherals ...
The Linux kernel is a free and open source, [11]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
FreeRTOS is a real-time operating system kernel [3] [4] [5] for embedded devices that has been ported to 40 microcontroller platforms. It is distributed under the MIT License . History
The kernel architecture's main benefit is that an application can be developed independently from a particular system configuration. This allows new modules to be added or replaced in the same application, so that specific scheduling policies can be evaluated for predictability, overhead and performance.
