Visopsys is an alternative operating system for PC compatible computers. Under development since late 1997, this system is small, fast, and open source. It features a simple but functional graphical interface, real preemptive multitasking, and virtual memory. Though it attempts to be compatible in a number of ways, Visopsys is not a clone of any other operating system. You can demo the distribution from a "live" CD or floppy disk.

Partition Logic 是一款免费而且开放原始码的磁盘管理工具,使用者不仅能够透过它来创建、删除磁盘,而且也可以利用它来达成商业软件才具有的调整分割区大小的功能。这个功能对于许多使用者来说可是梦寐以求的喔,因为常常会有使用者在分割磁盘之初未事前计划好容量,等到使用了依段时间后才发现磁盘大小分配不恰当的情形,这个时候就可以利用 Partition Logic 的调整扇区大小的功能,在不损坏原有数据的情况下来重新分配扇区的大小。对于想要对磁盘内容进行备份的使用者而言,Partition Logic也提供了磁盘数据完全复制的功能,让使用者可以轻松快速地将数据由A磁盘转移到B磁盘,确保数据的安全性。这么棒的功能,原本都是要在付费购买的软件中才能够拥有,但是现在却可以免费享受到,聪明的使用者们还在等什么呢?马上就来试试Partition Logic带来的超强功能吧!

VERSION 0.69

24/09/2007

Overview: Four months in the making, this is a maintenance release comprising the final round of tweaks and bug fixes to the 0.6x series of Visopsys, featuring lots of work on the USB subsystem including support for USB mice/keyboards and hubs, tuning of the FAT filesystem driver, usability fixes for various user programs, and loads of OS kernel and C library improvements and bug fixes.

* Lots of improvements to the USB subsystem, the UHCI controller driver, and the USB SCSI disk driver.

* Added support for USB mice and keyboards

* Implemented a driver for USB hubs.

* Extensive tuning of the FAT filesystem driver, and the scanning of the FAT at mount time is much faster. Also fixed a small fragmentation bug, and turned a bunch of extraneous error messages into debug messages.

* The FAT filesystem driver no longer stores the entire FAT in memory.

* Added basic hardware detection for OpenHCI (OHCI) USB controllers so that they're at least indicated correctly at boot time.

* Improved checks for removable (CD, floppy, flash, etc.) media changes, invalidating the disk cache when the media changes.

* The 'filebrowse' program now shows the name of the current directory, and remembers any selection from the parent directory so that it's still selected if the user goes back up.

* Re-wrote much of the PS/2 mouse driver, primarily to deal with out-of-sync situations that could cause the mouse pointer to jump around.

* Re-added the 'logout' program to the basic installation -- without it there's no 'logout' option in the shutdown menu.

* Added a "linked list" implementation to the kernel for generic management of lists of pointers.

* Replaced bzero() calls in the kernel with kernelMemClear() calls.

* Updated the kernel's exception handler so that it will print exception address/symbol information even if multitasking isn't yet enabled.

* Added a '-n' option to the 'format' program, for specifying the volume name (label).

* Added a kernelDebugHex() function for doing simple hex dumps.

* Renamed the kernelKeyBoardDriver to the kernelPs2KeyboardDriver and the kernelPS2MouseDriver to the kernelPs2MouseDriver

* Got rid of the kernelMemoryReleaseSystem() function -- the regular kernelMemoryRelease() function can now handle releasing system memory blocks.

* The printf() and family %x format specifiers now print only unsigned values.

* Fixed: The Disk Manager showed partitions with the starting and ending cylinders determined from information in the partition table. This could be inconsistent (particularly in the case where geometries are guessed) with the geometry of the disk as seen by the kernel.

* Fixed: Using the Disk Manager with a hotplugged USB disk caused a divide-by-zero exception because the geometry values were zeros. The kernel SCSI disk driver now determines/guesses a geometry, and the Disk Manager now ensures that the values are non-zero.

* Fixed: Using the Configuration Editor to open a config file with no predefined variables resulted in a window with no 'list' component.

* Fixed: The text editor couldn't create a new file.

* Fixed: The 'filebrowse' program could crash when you using the 'del' key to delete files.

* Fixed: An occasional problem with ejecting ATAPI (CD-ROM, etc) devices in the kernelIdeDriver code.

* Fixed: Spurious interrupts could cause the kernelPicGetActive() function call to hang in the driver.

* Fixed: Command line option processing for the 'format' and 'rm' commands.

* Fixed: Calling the component 'set visible' function didn't work for containers.

* Fixed: USB "can't enable port" messages.

* Fixed: Error messages were being double-printed on the screen when console logging was in effect.

* Fixed: The USB UHCI driver was not returning the number of bytes transferred for transactions with a data phase.

* Fixed: Some window ops were generating error messages because they were trying to malloc() 0 bytes when the root window contained no components.

* Fixed: The _xpndfmt() function was causing an exception when printing pointers in hex using the %p format specifier.

* Fixed: The _xpndfmt() function was causing a divide-by-zero fault when printing GUIDs in the Disk Manager.

* Fixed: The kernelDiskGetMediaState() function wasn't locking the disk before accessing the disk structure.
