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.
- Find or set the active system partition only once, when we start the
formatting stage. If the system partition is to be created in some
non-partitioned space, we create it.
- A file-system check is always scheduled for both the system and the
installation partitions.
- If the system partition was already formatted (which usually means
that it already existed on the system), don't ask for formatting it.
CORE-13205
- For each partition to be formatted, the file-system menu list is
re-created, in order to display only the FSes that are compatible
with the selected partition, and allow to give the user the choice
to keep the existing file-system only if the selected partition was
already formatted.
- Check whether the user attempts to delete the partition on which
the installation source is present, only if it is not "new" and is
formatted.
- Check first whether the current partition is the system partition,
before displaying the CONFIRM_DELETE_SYSTEM_PARTITION_PAGE.
- 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.
This stub is responsible for providing the UUID seed to the kernel.
For now, it generates a purely random seed - MAC address support
is to be added.
Because it's purely random seed and local the machine (not tied
to the MAC address) it's made so that ExUuidCreate keeps returning
RPC_NT_UUID_LOCAL_ONLY. It won't fix failing test for now.
Nota: this service shouldn't exist as it. It should be implemented
though rpcss DLL for both rpcss service (network service) and
dcomlaunch service (local system service).
Because rpcss is EXE based and wine-synced for now, I prefered
stubbing a new service. This will have to be changed at some point.
- Implement the save/load handler for this feature
- Check the "Use Click Sound" item state accordingly depending if it's enabled or disabled
- Use PlaySoundW() to play the wave sound file from resource
- Add the WAV sound click file. The work is made thanks to Midori Mizuno
Prevent nslookup.exe from crashing when executed in a ROS VM with no network
interfaces. This is due to a NULL pointer dereference occurring if
`GetNetworkParams` in `main` fails with an error other than
`ERROR_BUFFER_OVERFLOW`. In this case, `pNetInfo` remains initialized to
NULL, causing `strncpy` to crash.
