Nowadays more and more people try to install ReactOS from removable
drives (e.g. USB sticks) onto fixed HDDs, or try to install it into
USB sticks too.
Both fixed and removable drives, as well as partitions on these, are
represented in NT using the same device name format:
\Device\HarddiskM\PartitionN ,
with an increasing disk number M. Using this number for building the
corresponding firmware-specific ARC multi(x)disk(y)rdisk(z) path used
by the NT/ROS loader (FreeLdr, ...) is then prone to error since there
may have been removable drives inserted and accounted for in the
calculation of the disk number. These drives must be correctly
subtracted in order to generate the correct ARC path, valid once all
the removable drives have been ejected (which should also be the
situation seen from the BIOS when booting up, except of course if you
boot on a USB stick).
This problem is now solved. Note that it matters only for the disks
that have also been enumerated by the firmware (BIOS; Int 13h). We
don't have to care about the other drives, since the ARC path will be
of a different format and will not use the disk number (instead, the
SCSI coordinates are used).
We also try to enumerate all the disks found in all the possible disk
adapters and controllers enumerated in the Hardware registry tree
(and that are visible by FreeLdr) in order to cover all.
Finally, we detect whether a disk reports as a "super-floppy", i.e.
an unpartitioned disk with a valid VBR. This is indeed how a standard
floppy disk looks like, or how USB sticks are partitioned on Windows.
Such disk is reported has having only one single partition starting at
the beginning of the disk, with partition number == 0, its type being
FAT16 non-bootable.
This allows us to forbid creating any new partitions on such disks.
Note that accessing either \Device\HarddiskN\Partition0 or Partition1
on such a disk returns the same data.
Note also that on the contrary, regular MBR-partitioned disks would
report at least four partitions entries, instead of just one.
The other improvements are:
- Do *NOT* write any MBR on a disk partitioned as "super-floppy".
CORE-13703
- Fix the computed disk identifier, of format: %08x-%08x-%c .
The numbers are respectively the checksum of the first sector, and
the disk signature. The terminating letter is A or X, depending
whether the first sector ends with 0x55AA/0xAA55 or not (see also
commit 5053f1f5).
- Warn if the user attempts to install ReactOS on a disk that is not
visible by the firmware of his computer, because it may not be
bootable.
- Add also some validation ASSERTs and simplify the code here and there.
- The installation partition is called "InstallPartition", while the
global "CurrentPartition" is the disk region currently selected in
the partition UI list, on which prtitioning operations are effectued.
- Extend CheckActiveSystemPartition() to use an optional alternative
disk or partition in case the actual system partition (present in the
first disk) cannot be used, e.g. because we don't support writes on it.
- Make some partitioning functions not dependent on the selected "CurrentPartition".
- Add some sanity checks.
- Improve some of the "is-partitioned" checks.
Similarly to FMIFS this structure should be private. Instead file-system
names are passed to the helper functions, allowing to use the names
returned by the FS drivers. The names are then internally mapped to the
corresponding FS providers.
In particular this allows to handle the "RAW" file-system and to assign
the 'Unformatted' flag to partitions having this FS.
Finally this helps us refining the checks performed to see whether the
current "active" system partition uses a supported file-system.
- Within the function's body code, check the status values returned by the called functions.
- Change the BuildInstallPaths's function type to NTSTATUS instead of VOID (and check the status of InitDestinationPaths() as well.
By default, we still fallback to FAT if nothing asked, or if there
is an invalid input.
0 is FAT, 1 is BtrFS. This can be grown as soon as we add more IFS.
- Add checks for GPT disks and either fail or ignore the disk,
depending on the operation being executed.
[USETUP][REACTOS] Display the disk style more accurately.
CORE-7749
- Correctly insert discovered partitions in sorted order of StartSector,
and verify that they do not overlap (-> check for broken partitioning).
May help for CORE-10898.
- Use the correct reported partition numbers that may be modified after
partitioning changes, and that need to be used when opening
\Device\Harddisk'M'\Partition'N' files. This is achieving by
retrieving the returned value of the IOCTL_DISK_SET_DRIVE_LAYOUT call.
Distinguish them from the "on-disk" partition numbers that are the ones
that enumerate the partition in partition-table order (and is the order
known by e.g. the BIOS), and that should be used to construct the
destination ARC path.
May help for CORE-4870, CORE-13205.
- Simplify a lot of duplicated code by using helper functions.
Always perform the partition validity checks when creating new
primary/extended/logical partitions, and also when a new partition
is automatically created when unpartitioned space is selected for
ReactOS installation.

This will allow compatibility with modern OSes and
modern disk management utilities.
It will also improve performances by properly aligning
partition start.
And it will let enough room at the begin of the disk
for 3rd party bootloaders.
WARNING: this is not compatible with previous partition
model, and old one will likely not be compatible. You'll
have to erase your whole partition table and start from
scratch.
- SETUPLIB and USETUP: Convert PARTENTRY::DriveLetter to WCHAR.
- SETUPLIB: Retrieve volume label.
- SETUPLIB and USETUP: Move the partition types (IDs) table from
USETUP to SETUPLIB so that they can share it with the 1st-stage
GUI installer too. Also take the opportunity to update the table
with information from http://www.win.tue.nl/~aeb/partitions/partition_types-1.html
and cross-checked with the list from Paragon Hard-Disk Manager.
- USETUP: Simplify PrintPartitionData().
- Add some code comments.
- BOOTDATA: Use standard INF signature string, so that they can be
opened successfully using ReactOS' or Windows' setupapi.dll with
the INF_STYLE_WIN4 style.
- SETUPLIB: Use the correct INF_STYLE_* INF styles in SpInfOpenInfFile() calls.
- REACTOS : Switch thread locale to user-specified LocaleId when calling
SetupOpenInfFileW(), so that the correct localized strings are used.
- In PrepareCopyInfFile(), explicitly use AddSectionToCopyQueueCab()
to retrieve the files from the CAB INF.
Otherwise if one continued to use and rely on AddSectionToCopyQueue()
to do this job instead, bad things could happen like, re-enumerating
twice or more (and adding them to the file queue) the same files.
This is because in the new code AddSectionToCopyQueue() can be called
many times to deal with different SIF file sections. The old code then
called AddSectionToCopyQueueCab() in turn, but on the same list...
Now the steps performed are clear, and everything works as intended.
- Simplify the code that computes the full source and destination paths
for the files to be copied and directories to be created, using helper
functions.
- Compute the source file and target location from the TXTSETUP.SIF
entries in a NT-compatible manner.
- Use adequate access flag when opening symbolic links.
- Simplify the prototype of UpdateRegistry() since now both Setup INF
handle and settings lists are inside the USETUP_DATA structure.
This allows using some of the SetupApi.dll functions when SETUPLIB is
used in the (Win32) GUI 1st-stage installer "REACTOS", while using the
custom implemented NT-aware functions in "USETUP".
- Move a great deal of global variables into the USETUP_DATA structure
(the SetupInf, the SetupFileQueue, the generic lists...).
- Place the common setup initialization code into an InitializeSetup()
routine, and the cleanup code into FinishSetup().
- Implement the setup-code part support for the TXTSETUP.SIF setup
source path override variables "SetupSourceDevice" and "SetupSourcePath"
(see CORE-9023); support for them in SETUPLDR will be added later.
This includes also to remove the created symlinks.
Symlinks deletion is special, as one has to open first the symlink
itself (and not its target), then remove the "SymbolicLinkTarget" value
before really deleting the key. Of course everything must be done under
proper access rights.
Additional changes:
- Change prototype BOOLEAN CmpLinkKeyToHive(...) to NTSTATUS CreateSymLinkKey(...).
- Silence few DPRINTs.
- Document some FIXMEs that I need to inspect later on ReactOS.
- HKEY --> HANDLE.
- It can therefore be also used by the 1st-stage GUI setup.
- Rename some function parameters to clarify what they should be.

[USETUP] Improve usage of ERROR_TXTSETUP_SECTION and ERROR_CABINET_SECTION error codes, correctly display associated error message, and remove a deprecated string.
- Apart from allowing a UI cache variable that may be used when
displaying GENERIC_LIST_ENTRY-ies, do not store any display strings
associated to these list entries. They should be instead computed only
when initializing a list UI (or a combo-box or list control if the
code is used in Win32 environment).
For this matter a callback is provided to InitGenericListUi() that
does the job of computing the displayed string corresponding to a
given GENERIC_LIST_ENTRY.
- Simplify the calls to InitGenericListUi(), and refactor the
RestoreGenericListUiState() function.
- Use for-loops for iterating over GENERIC_LIST items.
- Adapt the storage data format for lists of settings items.
- The txtsetup.sif INF format specified in LoadSetupInf() should not be
INF_STYLE_WIN4 (to be investigated...).
- Use OBJ_CASE_INSENSITIVE when initializing object attributes
(no actual reason why to keep case sensitivity there).
- Check the success of a RtlStringCchPrintfW call in EnumerateReactOSEntries().
- Explicitly check for returned STATUS_NOT_SUPPORTED from ChkdskPartition()
or FormatPartition(), and display an appropriate error message.
- Remove some left-over comments but also explain why I kept some
commented code (mainly for future reference).
Comment about the status of two '#if 0'.
[SETUPLIB] Fix some uninitialized variables (caught by clang-cl).
Also, initialize NtName->Length in return paths in ResolveArcNameManually().
Only convert to ANSI when needed (e.g. in the display code for usetup).
The 1st-stage GUI setup will however use the UNICODE strings directly.

[SETUPLIB][USETUP] Start massaging the MUI files and split up what concerns only the usetup "resources",
and what concerns general language parameters (in the setuplib).
It may be interesting to retrieve the language parameters
from INF file (e.g. intl.inf) (suggested by Giannis).

[SETUPLIB] Add the necessary headers to mui.c to be able to compile.
[USETUP] Comment out the languages that don't have any resources.

[SETUPLIB][USETUP] Adjust MUI and settings code.
- Re-enable settings code concerning language, keyboards & layout
in the setuplib, and remove the old code in usetup.
- Remove useless code in setuplib's mui.c.
- Rename usetup's MUI "LanguageList" into "ResourceList" so as to
avoid colliding with the "LanguageList" of setuplib.
- Add the magic CMakeLists line "add_definitions(${I18N_DEFS})" that
I forgot previously, that caused the "LanguageList" of setuplib to be empty!
The code compiles and works during my tests.

[USETUP] Code adaptations.
- Transform some do{}while() loops into while(){} ones, since the lists on which we work may only contain one single {NULL} element.
- Modify MUIGetOEMCodePage() call after r75719.
- Use PCWSTR where needed.

[USETUP] Adjust some MUI & settings calls, following the commits r75719, r75720 and r75721.

[INPUT.CPL] Adjust inclusion of "muifonts.h" (commit 3dbd44f) due to changes introduced in r75711 and r75715.
This code is moved ther since it'll be needed for 1st-stage GUI
installer as well.
The code dealing with keyboard layouts is however not moved yet,
since it uses MUI* functions from usetup.
I'll try to think how to include that in setuplib...
svn path=/branches/setup_improvements/; revision=75701
Move the bootsup.c code into the setuplib, as the code is generic
enough to be used by both USETUP and the 1st-stage GUI installer.
svn path=/branches/setup_improvements/; revision=75674
- Compute the installation source paths based on the full path of the
installer program that uses the setup library.
- Add INF_STYLE_OLDNT define in infsupp.h.
- Add some (silenced) diagnostic DPRINTs.
svn path=/branches/setup_improvements/; revision=75667
- Use correct inf style flags in SetupOpenInfFileEx() calls when opening
txtsetup.sif and unattend.inf. Technically txtsetup.sif would be
INF_STYLE_WIN4, but since we use "$ReactOS$" as its version signature,
it would not work when opening it with setupapi.dll functions.
Hence this flag is combined with INF_STYLE_OLDNT too.
- Don't fail if opening the \SystemRoot symbolic link doesn't work
(usually due to incorrect access rights); in that case, just use the
installer image file path as the installation source path.
