- Make "ReactOS Server" the default product option again instead of "ReactOS Workstation".
- Write "Service Pack" info onto registry.
- Add ProductOption option to bootcd unattend.inf.
- Delete IDC_PRODUCT_SUITE and IDC_PRODUCT_TYPE controls.

Also turn off debug messages to screen before setting up the CPU (To print a character to the screen on some ports the MMIO access should be executed, so it throws an exception).

This prevents ReactOS asserting when 'My computer'
is opened, while it tries to send commands to floppy drive.
Many thanks to patches author Doug Lyons.
The regression was introduced by 0.4.13-dev-1081-g
eeff926ede
patch was committed to 0.4.13rls and 0.4.14rls as well.
Today it was committed to master as well, as
the initially planned investigation for the root cause
did still not happen and we can not afford the time
to retest and workaround this over and over again.
Thank god that Oleg Dubinskiy was still around to retest
this again and confirmed it can still happen, because
unlike initially, personally I was not able to reproduce it
today anymore!
Since every release was work-arounded, we did never
expose the bug in any final release.
According to PC-9801 Bible p. 50, divisor for PIT will become unsupported in some cases after having removed the fractional part. Replace 19200 value with 9600 which is supported by both 10 MHz and 8 MHz machines.
Remove RTC switch from configure.cmd, now MSVC runtime checks are
supposed to be enabled/disabled via CMake define (-DRUNTIME_CHECKS=1)
Prepare for adding more dynamic analysis options
which implements the required functionality.
ntdll and ntoskrnl now have a wrapper for this, with SEH.
This protects the function against malformed / bad images,
whilst still being able to use the code in freeldr et al.
Idea from Thomas.

This PR enables the developers to include the CJK standard fonts into ReactOS by adding them in Folder modules/optional. This feature is for test purpose only. You may not use the fonts illegally.
The embeddable font files are: mingliu.ttc, simsun.ttc, mssong.ttf, msgothic.ttc, msmincho.ttc, gulim.ttc and batang.ttc.
CORE-9619
- Changes in device detection code:
* Properly check device signature.
* Сorrectly reset the IDE controller.
* Remove check for device type code.
- Fix CD-ROM sector read issue:
* Changed ATAPI packet opcode to be more universal (Some devices may not have READ12 support).
* Always use 2048 bytes as sector size when reading the data from a disc.
* Modify WaitForFlags() to stop polling if the error bit was set.
* Changed timeout to 31 seconds (ATA default value).
- Add more informational messages in DEBUG mode.
- Fix invalid IDE register value.
- Fix registers names.
Tested by Stanislav Motylkov and Daniel Reimer on XQEMU and on real
hardware MS Xbox revision 1.3 with Philips DVD drive.
It has also been tested manually on PC with a SONY DVD drive.

Surprisingly this also happens to "fix" random "Invalid Opcode" exceptions in XQEMU.
(But I think it's more like a coincidence... --hbelusca)
CORE-16627 CORE-16216
The first part of PC-98 Port - https://reactos.org/wiki/PC-98
- Add FAT12 file system boot sector for NEC PC-98 series.
- Add a new build target for a PC-98 bootable floppy disk.
- Add a new sub-architecture into config.cmake.
* [FREELDR] Cache the drive geometry in the PcDiskReadLogicalSectorsCHS()
Speed up the loading time a bit.
* [FREELDR] Generalize the cache to all the geometry data + INT 13h extensions-supported status.
The data structure used is "PC_DISK_DRIVE".
- Adapt the associated functions;
- Make DiskGetExtendedDriveParameters() private to pcdisk.c
- Introduce PcDiskDriveNumberToDrive(), that is similar to the XBOX
function XboxDiskDriveNumberToDeviceUnit(), that retrieves a valid
pointer to the cached disk corresponding to the given BIOS DriveNumber.
If needed the cached data gets initialized.
- Make XboxDiskDriveNumberToDeviceUnit() simpler by just returning the
pointer to the corresponding drive, of NULL if there is none.

Add AppliedDPI DWORD registry value 0x00000060 (96 DPI) into HKCU\Control Panel\Desktop\WindowMetrics registry key. For now it does nothing, since saving DPI registry settings is not implemented yet. It's required only for ViStart 8 to be started successfully (with MS VB6 Runtime installed and wshom.ocx replaced). CORE-13877

Add "Command Prompt here" menu item to the Right-click menu of normal folders and drives. Currently, this menu item doesn't work correctly because of the bug of pushd. CORE-12150
Triggered by a fix attempt by M.Harmstone in PR #1905.
- Introduce #defines and helper functions so as to initialize the
descriptors in a human-readable and tractable way, without magic values.
- Rework some comments.
- Document what the changes are in (Longhorn and) Vista+.
Data has been obtained through using the WinDbg command: dg 0x00 0xFF
(for example), that lists all the selectors from 0x00 to 0xFF included.
See https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/dg--display-selector-
for more details.
- Implement support for the "RDIMAGELENGTH" and "RDIMAGEOFFSET" boot
options. Fixes CORE-15432.
- Separate the initialization of the global gInitRamDiskBase /
gInitRamDiskSize variables from the FreeLdr command-line, and the
actual initialization of the internal variables of the RamDisk.
The latter are initialized via calls to RamDiskInitialize().
- Implement 'SeekRelative' mode in RamDiskSeek().
- Make RamDiskLoadVirtualFile() internal function that gets called by
RamDiskInitialize(), and we use the latter in the NT loader instead.
Basically it appeared that without this fix, the CPU was somehow residing
in an inconsistent state, that made it crash when a full 16-bit real-mode
to 32-bit protected mode transition occurred. (Encountered when trying
to load Linux, see problem description below.)
In that situation, Bochs reports that the CPU is in "compatibility mode".
The fix is based from information from Fig.1-6 "Operating Modes of the
AMD64 Architecture" (page 12) and Chapter 14 (pages 429-446) of the
"AMD64 Architecture Programmer’s Manual Volume 2: System Programming"
https://www.amd.com/system/files/TechDocs/24593.pdf
*** THE PROBLEM ***
When booting Linux using x86 FreeLdr everything goes well.
When trying to do the same using x64 FreeLdr, the Linux code (both the
boot sector, the setup sector and the main kernel contents) is all
correctly loaded and relocated in memory as in the x86 case. We then pass
control to the decompressing code that appears to succeed. However, once
it has finished and "Parsing ELF file..." step has been run, the next
step "Booting the kernel..." crashes with a CPU Triple-Fault.
This problem **DOES NOT HAPPEN** when booting from GRUB.
