Partition Logic v0.9 ISO

Попробовал из "ФИНАЛ"а версию Partition Logic v0.75 - 1.84 MB - Всё работает на ура! Целая мини ОС с "кучей" программ!!

All of the background wallpaper images are new, the colours have changed slightly, and a number of the GUI components have had their appearances updated.
Menus have been updated for the German, Spanish, Russian and Turkish languages.
Added wide-character and multibyte character (UTF-8) support throughout the operating system – to the fonts and charsets, the GUI, the C library, etc. It has replaced the ISO-based internationalization schemes. Although some knowledge of ISO codepages was kept, things have been more-or-less entirely switched over to Unicode.
Added VMware mouse integration, so that a Partition Logic guest coordinates with the host to automatically grab or ungrab the mouse cursor as it enters or leaves the window. Requires the option to be enabled in VMware.
Added a computer chip icon, ‘chip.ico’. To start with, the Computer Browser will use it for RAM disks.
Did some tidy-up of the translated .po files – mostly updating c-format strings’ parameters, punctuation, and newlines.
Fixed: The Computer Browser program could show mismatches between disks and icons, if it didn’t have an icon for a particular hardware type (specifically, RAM disks). Made it more robust, with a default icon.
Fixed: The Disk Manager’s creation and resize dialogs were full-screen, and looked all messed up.
Fixed: Several of the programs didn’t have .pot translation files.
Plus dozens of other improvements to the Visopsys operating

По скриншотам похоже, что прогу надо юзать в DOS 6.22 или Windows 3.11.

Added proper support for composite USB devices, treating each interface as a separate device at the kernel level.
The CPU driver no longer determines the CPU frequency using the RTC, but rather using the system timer and a short countdown. This shortens the boot time by 1-2 seconds.
It is now possible to drag scrollbars and sliders without keeping the mouse pointer strictly within the component or window.
Added language-specific kernel configuration files for Spanish and German
Improved the window system graphics performance. A sequence of drawing and updating operations can happen without the visible screen data needing to be updated every time.
Improved the performance of the PS2 mouse driver. It was very laggy on some systems.
Added basic functionality for virtual keyboards. A virtual keyboard device is now created by default, and key strokes can be sent to it.
In the Display Settings program, the desktop wallpaper sample is now scaled to the screen aspect ratio, and if no wallpaper is chosen, the sample is filled with the desktop color.
The command window no longer requires typing a space character before or after special symbols, such as an ampersand.
Fixed and standardized command-line option processing for most of the included programs.
Re-engineered the GUI ‘canvas’ component for better drawing performance.
The window system’s icon code that formats labels has been re-written, and will now split the text label with newlines.
The window ‘canvas’ component will now auto-fill with a custom background color, if one is specified.
Made the thickness of slider bars and scroll bars configurable in the window.conf file.
The USB subsystem now adds kernelDevice entries for USB devices that aren’t supported (aren’t claimed by device drivers) so that the device listing is more complete.
USB work: updated the hub definitions to make USB version compatibility more obvious, split the keyboard and mouse drivers into separate files, and removed the combined HID one. Improved the collection of interface and endpoint data. Improved support for composite (multi-interface) devices by requiring drivers to ‘claim’ individual interfaces, instead of the whole device. Reduced the overhead of setting EHCI static endpoint characteristics+capabilities, and fixed the setting of USB 2.0 hub address and port for low- and full-speed devices.
Changed the USB drivers so that a physical device will only have its configuration set once, in the case where drivers are claiming and using multiple interfaces.
Added a longer ready timeout to the USB disk driver.
The XHCI (USB3) driver no longer disables I/O and memory decoding in PCI when detecting controllers.
The kernel loader’s gzip file classification no longer requires the file to qualify as binary; it’s possible to have uncompressed text blocks/members inside the archive, which can cause the gzip file to be considered text by the loader.
Reduced reliance on the system timer, particularly in the disk drivers, in favour of the kernelCpu functions that measure time in milliseconds.
The IDE disk driver’s ‘identify device’ code now uses the data structure used by the AHCI SATA driver.
When locating the boot device, the kernel no longer relies on the OS loader to pass the LBA of boot sector. Identification is now based strictly on the boot sector signature.
The floppy disk driver has been updated so that it won’t attempt to support ‘type 16? (removable ATAPI/USB) drives.
The window library’s functions for making thumbnail images have been updated to allow images to be stretched to the maximum size, and to fill any unfilled area with a background color.
Fixed: The kernel’s fileStream code was not correctly handling streams opened in ‘append’ (write-only) mode.
Fixed: The kernel’s file stream code was not keeping track of/setting the file size correctly.
Fixed: The EXT filesystem driver had a bug in its readFile() functionality. When the inode uses block lists, and the starting block number is greater than the number of ‘direct’ blocks, the driver was simply reading the first sequence of indirect blocks, without regard to the starting block number.
Fixed: The AHCI SATA driver could fail to detect disk(s) with the error message “AHCI port %d BSY or DRQ set – skipping device detection”.
Fixed: Incorrect status and error register writing functions in the USB1 UHCI driver.
Fixed: The IDE driver wasn’t dealing well with individual controllers and channels operating in ‘compatibilily’ mode (alongside others that may be native). Now, we examine each controller and channel, whether it has PCI I/O ports and interrupts, and whether it should continue to stay in compatibility mode or be switched to native.
Fixed: Added PCI definition for class:subclass FF:00 to suppress spurious warnings about unknown subclasses.
Fixed: Removed the automatic USB Mass Storage reset during device enumeration of USB disks. Some devices, on some controllers, stop responding, and it seems unnecessary.
Fixed: The EHCI (USB2) unregisterInterrupt() function was incorrectly unlinking interrupt queue heads.
Fixed: The middle and right mouse buttons were swapped for all USB boot-protocol mice.
Fixed: XHCI (USB3) interrupt handling to allow concurrent interrupt and non-interrupt communication between multiple endpoints.
Fixed: In the window library’s file browser widget, some of the default icon names were wrong, not up to date.
Fixed: The window library’s windowCenterDialog() function, so that it won’t place a window at negative coordinates (off the top or left edges of the visible screen).
Fixed: In the Disk Manager, when resizing a partition in graphics mode (and other sliders generally) merely mousing over the slider could cause the text field to be changed.
Fixed: When setting the video resolution in the Display Settings program, the video mode file was not having its size set correctly, and an error message “File has not been opened for writing” would appear on the command line.

Overview: This maintenance release is focused on improved quality, rather than new features. The EXT (Linux) filesystem driver has been re-engineered, the main Partition Logic program has been fixed in numerous ways, and hardware drivers and subsystems such as USB, APIC, and RTC have been tuned.

Did a fairly major overhaul of the EXT filesystem driver, adding more adaptive feature support, plus support for EXT4 flexible block groups and basic support for EXT4 extent-based files. Also fixed a little bug in the formatting functionality (setting the EXT_INCOMPAT_FILETYPE flag in the superblock).
Improved the new APIC driver so that it considers the correct priority order when returning the number of the active interrupt. This fixes failures when using the VirtualBox emulator, and some failures seen with the Qemu emulator.
Partition Logic is slowly transitioning away from the notion of ‘cylinders’, and towards showing the user units of sectors, megabytes, etc.
Some modern systems don’t allow manual control the A20 address line, but work anyway. The OS loader will still print an error message, but it will no longer terminate booting with a fatal error in such cases.
Added a extra support for multi-interface (composite) USB devices.
Improved the EHCI (USB 2.0) driver and the way it manages queue heads and the periodic schedule. Interrupt queue heads for devices are no longer placed directly into the periodic schedule; instead linked, interval-specific queue heads are used. Linked lists of queue head items are now chained correctly.
All USB device drivers now check to make sure a device hasn’t already been ‘claimed’ by another driver.
All USB transaction creators now specify timeout values as appropriate, and all of the USB host controller drivers now pay attention to those.
Added kernel locking to the XHCI (USB 3.0) driver.
Added a short delay to the XHCI (USB 3.0) controller driver, after setting the port reset bit, before reading it back to check for the ‘clear’. In some cases it can read clear straight away, but the reset hasn’t completed yet, resulting in device detection failures.
Fine-tuned the PS2 mouse and keyboard timeouts, and the USB keyboard typematic repeat timing.
Improved the layout code of the window library dialog boxes.
Got rid of the checks/warnings about disk geometry errors when performing a partition table check. We want to reduce reliance on legacy disk geometry, and frequent mismatches meant a lot of scary-looking warnings that probably didn’t amount to anything anyway.
The code for specific disk label types (MS-DOS, GPT) now specifies the first and last available sectors for data, and the starting and ending values for new/moved/resized partitions are adjusted to accommodate these.
Pasting a partition now requires committing changes, as with format operations, erases, filesystem resizes, etc.
When disks or partitions are erased, it now checks for mounted filesystems, and the kernel is now told to re-scan the filesystem types, the same as after a format operation.
Now checks for a mounted filesystem before deleting a partition.
No longer enables the ‘set active’ button/menu item when working with a GPT partition table. The option is meaningless for this disk label type.
Fixed: The VirtualBox emulator was not cooperating with the RTC driver, and the boot would fail/crash.
Fixed: A double-fault would occur if an exception was triggered before multitasking was enabled.
Fixed: ALT-TAB only worked for activating the top menu bar if at least one window existed (i.e. something in the ‘Windows’ menu). It now tries to activate the first menubar menu that has some menu items in it.
Fixed: Automounting filesystems (from mount.conf) failed if no mount point was set. The filesystems program doesn’t force the user to specify one. The kernel now attempts to use a default (/<diskname>).
Fixed: The data moving threads could calculate incorrect sector numbers when copying/moving data from the start of the disk, toward the end of the disk.
Fixed: Copying and pasting partitions between MS-DOS disks and GPT disks wasn’t working.
Fixed: An incorrect partition diagram with certain MS-DOS logical partitions. Empty spaces were being calculated using cylinder values, which aren’t necessarily set for logical partitions, by other software.
Fixed: Pasting a partition into an empty disk would clobber the first track, disk label, etc. of the empty disk.
Fixed: MS-DOS extended partitions were not having their logical sizes calculated correctly (Parted would complain about ‘overlapping partitions’).
Fixed: Corrected the numbers shown when querying the user for partition size, when creating or resizing.
Fixed: The horizontal sliders used for moving, resizing, and creating partitions didn’t update their associated text fields when moved with keyboard presses.
Fixed: The VSH cursor menu was corrupting memory by attempting to set the text cursor row to a negative number, when there were too many items to fit in the text area/screen. Also added better parameter checking to the kernelText.c code.
Fixed: a divide-by-zero error in the window library’s windowNumberDialog code, that would cause it to crash when the minimum and maximum values were the same.
Fixed: 2 bugs related to GUID generation; The structure was not being defined as ‘packed’, and separately, the kernelGuidGenerate() function was over-writing the end of the structure by 2 bytes when writing the node ID.
Fixed: The file browser program would crash when passed a relative directory name on the command line.

Неплохая вещь. Не пойму: почему заминусовали? В восьмимегабайтный исошник лив-операционку запихнули.

Overview: This harware-focused maintenance release adds USB 3.0 support,
improved USB 2.0 and USB hub support, an APIC interrupt controller driver,
plus several bug fixes and general quality improvements.

- Added USB3 (XHCI) support.
- Greatly improved USB2 (EHCI) and hub support.
- Added APIC interrupt controller support.
- Added support for detecting and parsing the Intel multiprocessor table.
- The USB layer code no longer sets device configurations by default.
It is now left up to the individual device drivers, when they determine
that a given device is supported. Configuring some unknown, built-in,
proprietary devices can cause other devices to stop responding.
- USB hub removal now triggers a recursive device removal for all
downstream things connected via the hub.
- If a mounted removable disk (such as a USB stick) is removed from the
system, a call to kernelFilesystemRemoved() will now act like a forced
umount - unbuffering files and removing the filesystem - without
attempting further accesses to the physical disk.
- Added new functionality to count interrupt hooks, and updated some
definitions and things in the PCI driver.
- Physical memory addresses are now treated as unsigned integer values
instead of void pointers.
- Added kernelMemoryGetIo() and kernelMemoryReleaseIo() functions for
automating the process of allocating/releasing aligned physical memory,
mapping it, and marking it un-cacheable.
- Added a kernelDebugStop() function to output a message and halt
execution when errors are encountered in debug mode.
- Added a kernelDebugRemoveFile() function as a companion to
kernelDebugAddFile()
- Fixed: In the computer browser, when clicking to mount a CD-ROM for
the first time, from a cold boot, the file browser that was launched
sometimes wouldn't start in the CD-ROM's mount directory.
- Fixed: In the file browser and the file dialog, the current directory
field started off disabled (greyed-out), but changing the directory
caused it to be redrawn as enabled (not greyed out). Components weren't
being re-rendered when their setData() functions were called.
- Fixed: A bug in the USB driver subsystem, in which a device
disconnection could cause the USB thread to go into an infinite loop.
- Fixed: Increased timeout values for SCSI 'start unit' commands, to
support various USB-attached disks (hard disks and CD/DVD drives that
need time to spin up).
- Fixed: An IDE disk controller driver bug where an unhandled interrupt
could result from selecting a nonexistent slave drive on certain
controllers. Also eliminated some redundant status polling.
- Fixed: Timing issues in the AHCI SATA driver related to CD/DVD drives.
- Fixed: Removed kernelMalloc() usage in kernelDebug.c which could cause
debugging output not to be displayed in an interrupt context.

Added Spanish and German translations for many of the user programs and GUI features. The user can select their language at the initial splash window.
Implemented a full SATA (AHCI) driver.
Implemented an ATAPI-over-USB driver for USB CD/DVD drives.
The code that detects GPT partition tables now checks whether the MS-DOS “guard table” is really a guard table, for more reliable GPT detection.
Improved SCSI disk initialization and fixed USB mass storage error detection.
Improved timing precision for IDE port polling timeouts and channel resets.
The USB 2 (EHCI) driver now handles controller-level error interrupts (host system errors).
The disk caching code now does more combining of cache entries for improved performance, reducing the number of disk writes.
Some memory management code has been reworked.
Changed the ‘bootmenu’, ‘copy-mbr’, and main Partition Logic programs to preserve the ‘disk signature’ field when installing a new MBR sector. This solves the problem of Windows requiring a ‘repair’ after installing the basic MBR or MBR boot menu. Also removed a warning/confirmation message about the repair thing from the ‘bootmenu’ program.
Part of the GUI system has been re-written, and GUI menus have been changed so that when the topmost menu item is selected, pressing cursor-up removes the selection.
The file dialog window now shows the current path the way the file browser program does.
Implemented mouse and keyboard threads to process input outside of the interrupt context, for improved stability.
The keyboard system has been redesigned.
Added typematic key repeats for USB keyboards.
Interrupt handlers are now disallowed from allocating or freeing memory, or changing the page tables/directories. This is a stability improvement.
Separated the window shell thread from the main GUI system
In the computer browser, inapplicable context menu items are now greyed out, such as ‘mount’ when a disk is already mounted.
Window menu items are now set to the same width as their parent menu, so that they’re all the same length when highlighted/selected.
Fixed: espectalll123 gave us a corrected Spanish keyboard map.
Fixed: Modified the USB 2.0 (EHCI) and SATA (AHCI) drivers so that they don’t fail if PCI bus mastering can’t be enabled.
Fixed: SCSI protocol command sizes and status packet handling for USB mass storage devices.
Fixed: On some systems, the NTFS code was not detecting the filesystem due to a debug-mode stack corruption issue.
Fixed: When clicking on the CD-ROM icon in the Computer Browser, there was an error message “Can’t mount disk on” (even though the CD could be mounted from the command line).
Fixed: USB 2.0 (EHCI) hot-plugging of USB mass-storage devices would tend to fail. The devices were being detected, but were generating communication errors.
Fixed: Dismissing a dialog box could cause the mouse pointer to disappear, when the mouse was somewhere within the parent window.
Fixed: Window resizing was very difficult and the correct mouse position to do so didn’t really correspond with the point where the mouse cursor would change to a resize cursor.
Fixed: Right-clicking in a menu would cause the menu item to show selected. Right-clicks aren’t currently relevant for menu items, so now we just ignore them.
Fixed: If a CD-ROM is mounted, the computer browser would access it continually. Made this better, but getting the disk properties causes the kernel to check the removable media status, so it’s not entirely avoidable.
Fixed: Right-clicking anywhere in the computer browser would bring up the context menu for the selected disk. That should only happen when right-clicking on an actual item. Added a getData() and eventComp() functions to the windowList component, to return the objectKeys of all the windowListItems, and to let windowListItems receive right-click context menu events, respectively.
Fixed: Moving the PS/2 mouse around during hardware initialization of its driver could cause a cascading boot failure.
Fixed: When there were windows on the screen, pressing ALT-TAB 2-3 times could cause a major GUI crash.
Fixed: When resizing images in the ‘view’ program, the window title bar didn’t update (with the correct zoom percentage) until the window focus changed.
Fixed: In graphics mode, the File Browser only noticed directory changes when a file is added or removed, but not sub-directories.
Fixed: The interpretation of the Linux swap fileystem header.
Fixed: Support for using images inside of GUI buttons
Fixed: Improved the stability of the Screenshot program.
Fixed: Pressing backspace at position (0,0) would cause the Edit program to crash.
Fixed: Clicking on the kernel binary in the file browser program would cause a crash in the kernel’s runtime loader

Overview: This release consists of hardware support updates and bug fixes, with particular focus on USB. Support for USB 2 controllers and devices has been added.

Added initial USB2 (EHCI) support.
Added a stub USB3 (XHCI) driver.
Improved the output of the Devices program so that it's a little bit more readable.
Improved the collection and recording of the CPU vendor string.
Did a bit more development of the simple ACPI driver.
Fixed: USB hub detection could happen twice - once during the controller's initial device connection detection, and again when device driver detection happened for hubs.
Fixed: The first (number 1) USB port didn't work on many systems.
Fixed: Certain USB hard disks not working, and/or causing boot failure.
Fixed: The AHCI driver no longer fails to initialize if PCI bus mastering can't be enabled.
Fixed: ACPI (soft) power off could cause some systems not to boot the operating system on the next attempt.
Fixed: Removed possible infinite loop condition in the 'real time clock' driver.
Fixed: When installed somewhere via the native installer (for example on a USB stick) with a FAT32 filesystem type, the volume label was not being set properly.
Fixed: The graphical native installer would often skip the password setting box (flashing up and then disappearing).
Fixed: The TAB key was not working when using a USB keyboard.
