- Modify DiskReportError() to use an internal "display counter", so that
imbricated DiskReportError(FALSE) ... DiskReportError(TRUE) can behave
as expected.
- Merge LoadAndBootDrive(), LoadAndBootPartition(),
LoadAndBootBootSector() into one LoadAndBootDevice() function + its
helpers (in progress...).
- "FrldrBootPath" -> "FrLdrBootPath";
- Get rid of GetFreeLoaderVersionString() and use FrLdrVersionString
directly instead;
- Rephrase some comments;
- Use RTL_NUMBER_OF();
- Reduce indent level in LoadOperatingSystem() and EditOperatingSystemEntry().
Bug fix:
- Fix DissectArcPath() for "ramdisk(0)" case.
- Move DiskStopFloppyMotor() calls into the implementations of
Boot(New)LinuxKernel() and Reboot() HW functions, and the explanation
comments in ChainLoadBiosBootSectorCode().
- Remove unneeded DiskStopFloppyMotor() dummies in ARM and PPC code.
- Use more adequate bitmask value to be sent to floppy's Digital Output
Register for shutting down its motor (based on OSDev & our floppy
controller driver).
- Add optional arguments BootDrive and BootPartition to
ChainLoadBiosBootSectorCode() so as not to modify explicitly the
FrldrBootDrive and FrldrBootPartition variables, that should remain
purely internal.
- Implement ChainLoadBiosBootSectorCode() for x64.
- Get rid of the machine-specific DiskGetBootPath(), and instead do its
job only once in the machine-specific InitializeBootDevices() (or in
MachInit() for PPC).
Cache the result of this operation into the globally-accessible
FrldrBootPath buffer. This avoids the unneeded calls to (Mach)DiskGetBootPath()
we used to do before.
Also remove the separate distinction between the PC and XBOX versions
of this functionality.
- Move the PC-specific DiskIsDriveRemovable() and DiskGetBootPath()
as well as the disk-IO-error functionality, back into the
corresponding PC-arch files.
- Simplify IniFileInitialize(), getting rid of IniOpenIniFile().
CORE-9023
FIXES:
======
- Fix parsing of the multiboot options string.
NOTE: They are not yet treated in a case-insensitive manner!
- Fix a bug in ArcOpen() so that it correctly skips the first path
separator (after the adapter-controller-peripheral ARC descriptors).
The path separator can be either a backslash or a slash (both are
allowed according to the specs); they were also already handled
correctly in other parts of the code.
- Fix DissectArcPath() so as to:
* **OPTIONALLY** (and not mandatorily!) return the path part that follows
the ARC adapter-controller-peripheral elements in the ARC path;
* make it correctly handle the (yes, optional!!) partition() part in the
ARC path, for the multi(x)disk(y)rdisk(z) cases.
ENHANCEMENTS:
=============
- Directly retrieve the default OS entry as we enumerate them and
build their list (i.e. merge the GetDefaultOperatingSystem() helper
within InitOperatingSystemList()).
- Directly use the opened 'FreeLoader' INI section via its ID in the
different functions that need it.
- Make the custom-boot and linux loaders honour the boot options they are
supposed to support (see FREELDR.INI documentation / template).
This includes the 'BootDrive' and 'BootPartition' (alternatively the ARC
'BootPath').
This also allows them to take into account the user-specified choices in the
FreeLdr custom-boot editors.
- Modify the FreeLdr custom-boot editors so as to correctly honour
the priorities of the boot options as specified in the FREELDR.INI
documentation / template.
- Use stack trick (union of structs) to reduce stack usage in the
FreeLdr custom-boot editors, because there are strings buffers that are
used in an alternate manner.
- Extract out from the editors the LoadOperatingSystem() calls, and
move it back into OptionMenuCustomBoot(), so that when this latter
function is called there is no risk of having a stack almost full.
- When building the ARC-compatible argument vector for the loaders, add
the mandatory "SystemPartition" path. This allows the loaders to NOT
call the machine-specific MachDiskGetBootPath() later on (this data is
indeed passed to them by the boot manager part of FreeLdr).
- Improve the FsOpenFile() helper so as to make it:
* return an adequate ARC_STATUS instead of a mere uninformative BOOLEAN;
* take open options, as well as a default path (optional) that would be
prepended to the file name in case the latter is a relative one.
- Make RamDiskLoadVirtualFile() return an actual descriptive ARC_STATUS
value, and make it take an optional default path (same usage as the one
in FsOpenFile() ).
+ Remove useless NTAPI .
- UiInitialize() and TuiTextToColor(), TuiTextToFillStyle(): load or
convert named settings into corresponding values using setting table and
a tight for-loop, instead of duplicating 10x the same parameter reading
logic.
- UiInitialize(): Open the "Display" INI section just once. Remove usage
of DisplayModeText[] buffer.
- UiShowMessageBoxesInSection() and UiShowMessageBoxesInArgv(): reduce
code indentation level.
ENHANCEMENTS for NT OS loader:
==============================
- Don't use MachDiskGetBootPath() but use instead the "SystemPartition"
value passed via the ARC argument vector by the boot manager
(+ validation checks). Use it as the "default path" when calling
FsOpenFile() or loading the ramdisk.
- Honour the FreeLdr-specific "Hal=" and "Kernel=" options by converting
them into NT standard "/HAL=" and "/KERNEL=" options in the boot
command line.
Note that if the latter ones are already present on the standard "Options="
option line, they would take precedence over those passed via the separate
"Hal=" and "Kernel=" FreeLdr-specific options.
Also add some documentation links to Geoff Chappell's website about
how the default HAL and KERNEL names are chosen depending on the
detected underlying platform on which the NT OS loader is running.
This fixes null pointer call bug, which was revealed in 85d44fc. Spotted by Mark Jansen. CORE-16216

- Factor out disk & partition opening in LoadAndBootPartition() and
LoadAndBootDrive() into a LoadAndBootPartitionOrDrive() helper.
- Use ARC paths and ArcOpen()/ArcRead() instead of calling the
machine-specific BIOS-oriented DiskGetPartitionEntry() and
MachDiskReadLogicalSectors() functions to open the disk/partition
and read their boot sectors.
- Don't forget to close the opened boot sector file in LoadAndBootBootSector().
- Add assertions for DiskReadBufferSize in PcMemFinalizeMemoryMap()
and EnumerateHarddisks().
- x86/amd64 only:
* Add a DisableA20 helper for disabling the A20 line, before rebooting
back, or chain-load a boot sector, into 16-bit world.
Also pulse the output port of the keyboard controller to clear out
its state after having set the state of the A20 line.
* In addition to disabling the A20 line when rebooting or chain-loading
a boot sector, reset the video back to 80x25 text mode.
- Reset the cursor position back to the origin when initializing or
terminating the TUI.
- DiskGetFileInformation() should return relative addresses -- relative to the beginning of the "device" (partition, or disk) in question.
- FatXSearchDirectoryBufferForFile() should assign file attributes.
- Minor code style improvements in FatOpenVolume().

- This allows getting the /NOGUIBOOT mode working correctly, as the latter
expects text-mode. Then, usetup (via BLUE driver) will change to a
different text-mode, or, GUI boot will change (via BOOTVID) to VGA
640*480 16-color.
- Always hide the VGA cursor.
- Remove also the deprecated boolean "Setup" in the *PrepareForReactOS()
functions.

- Multiboot support added back in FreeLdr MSVC builds so that it can be
booted using e.g. GRUB. See CORE-15563.
- Re-introduce the disk drive mapper code.
As the MSVC linker alone doesn't permit such control, the file uses
ASM language (C can alternatively be used), together with extra linker
command-line switches.
It is pre-processed 3 times: first for generating the ASM code, second
for the C code and the third time for generating the linker response
file.
In our case, the ASM code defines the __bss_start__ and __bss_end__
symbols that allow us to find the limits of the .bss section (which is
by the way automatically appended to the .data section by the MSVC linker).
The C code is used to specify the list of linker switches that can be
passed through the `#pragma comment(linker, ...)' directive (the can be
alternatively specified in the linker response section).
Finally the linker response section contains all the linker switches
that cannot be specified with the `#pragma comment(linker, ...)'
directive.
Using all this we can recycle the BSS initialization code, that has been
written originally for GCC only, also for the MSVC builds.
Also, remove the outdated .text16 section merging.
- Introduce the AddReactOSArcDiskInfo() helper to get rid of the
duplicated reactos_arc_disk_info usage scattered amongst different
files.
- GetHarddiskInformation(): If we cannot read the disk that has been
enumerated by the BIOS, return a default identifier string.
- GetHarddiskInformation(): The last character of the disk identifier
string corresponds to whether its MBR is "valid"/has the 0xAA55
signature (use 'A') or whether it's not (use 'X'). Tested on Windows.
- Split PcInitializeBootDevices() in two: the first part of this
function that enumerates hard disks from the BIOS is now moved into
EnumerateHarddisks().
- The 'ValidPartitionTable' field of the ARC disk signature records must
be initialized with correct value that is specified in the different
AddReactOSArcDiskInfo() calls.
Volume boot record is also implemented, it supports reading BTRFS tree structures with upto 64k node size.
This support required to change all path in Free Loader to lowercase for better performance.
