This new BootCD contains the functionality of both the original bootcd
(text-mode 1st-stage installer) and the livecd (that will include the
1st-stage GUI installer later).
Our separate livecd ISOs become obsolete, and this completely removes
the need for the so-called "hybridcd" ISO.
Some details:
- The "hybridcd" build target is completely removed, since now the new
BootCD *is* basically what we used to call "hybridcd".
- The "livecd" build target is kept so far (to minimize the code changes),
but internally I start to refer to it as "LiveImage", and is reduced
to a minimum.
A minimal non-bootable "liveimg.iso" is built (but currently not
included within the BootCD). Its purpose will be to implement the
"ReactOS Live" functionality as a RAMDISK.
(We currently don't support other file formats apart from ISO and
flat disk for a RAMDISK).
The "ReactOS Live" (non-RAMDISK) is implemented by adding to the
BootCD file tree the files from the LiveImage.
These files add two root directories, "Profiles" and "reactos"
(which is the SystemRoot for the non-ramdisk LiveImage).
- The minimal text-mode ReactOS installation used for the 1st-stage
installer, including USETUP itself, and the executable for the
1st-stage GUI installer and the reactos.cab (installation source),
are moved to the root directory called "i386" (ideally, one directory
per architecture).
- The "bootcdregtest" target, i.e. the ISOs we feed our testbots with,
are left untouched, i.e. they are only constituted of the 1st-stage
text-mode installation only, but placed in a per-architecture root
directory ("i386", etc. as for the bootcd).
- Remove the ACPI APIC/SMP entries from bootcd.ini. They will be made
available via the Advanced Boot Options F8 menu in Debug builds, for
testing purposes only, in a subsequent commit.

======================== ReactOS™ Version 0.4.x Updated October 9, 2021 ======================== 1. What is ReactOS? ------------------- ReactOS™ is an Open Source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft® Windows™ NT family of operating systems (NT4, 2000, XP, 2003, Vista, 7). More information is available at: https://reactos.org 2. Relationship with the WINE project ------------------------------------- ReactOS has always intended to work with the WINE project to share as much programming effort as possible. This mainly concerns User Mode DLLs and still happens to a degree today. Other areas of cooperation lie in applications and testing suites. 3. Future compatibility ----------------------- The ReactOS project, although currently focused on Windows Server 2003 compatibility, is always keeping an eye toward compatibility with Windows Vista and future Windows NT releases. 4. Supporting other System Applications --------------------------------------- The Windows NT architecture allows for subsystems, as does the ReactOS architecture. A subsystem is an implementation of the APIs of another operating system, allowing ReactOS to run applications from other systems. We are already looking at subsystems for: Java, OS/2, and DOS and possibly others in the future. 5. Is ReactOS legal? -------------------- Yes we are. All the code of ReactOS has been written from scratch by our developers. We go to great lengths to ensure that the code our developers create is clean, same applies to the variety of methods we use to understand Windows internals, including clean room reverse engineering, using existing documentation freely available both in books and on the web, using extensive tests (tens of millions) which apply black box engineering methods against both public and private APIs exposed by the operating system. 6. Tutorials ------------ Developer and User Tutorials: https://reactos.org/wiki The tutorials contain more information on the project, compiling and testing ReactOS - amongst other topics. Contributors to the project are always welcome. 7. Frequently Asked Questions ----------------------------- Some of your questions may be answered in: https://reactos.org/faq In addition, the ReactOS forum: https://reactos.org/forum may contain complementary, yet non-official, information. 8. Authors ---------- This document was originally written by Jason Filby (jasonfilby@yahoo.com) and is now occasionally updated by various contributors.
