NEWS file for DOSEMU ==================== This file contains a list of user visible changes in DOSEMU. For the raw developer changelog please refer to ChangeLog. Version 1.3.5 (2007-04-27) ============= * A new sound system is available, written by Stas Sergeev. It is for now an optional run-time option, $_sound=(2). * Lredir can now automatically find a new drive (Ryan Underwood, Stuart Axon). * CPUEMU fixes (many by Michael Karcher). This also means that DOSEMU now runs more stable on x86-64. * Other fixes, affecting printer handling, MMX/SSE FPU state preservation, DPMI, Linux console graphics PCI handling on x86-64, the position of . and .. in "dir", UTF-8 multibyte input in terminals, SDL key handling, a double mouse cursor in Arachne in X, and "make install".

Drive Z: is now a read-only drive with all the DOSEMU and FreeDOS support files. * Clarified the copyrights and replaced some code with unclear origins. The disclaimer acceptance has been weakened. * Added native 64-bit support for x86-64, which, similarly to the 32-bit version, uses CPU emulation for V86 mode, and runs DPMI code natively. Most of the code is now 64-bit clean but a few cases may not work yet. * The CPUEMU simulator is now a runtime option, activated via $_cpuemu="vm86sim", or $_cpuemu="fullsim". Improved correctness of CPUEMU. * Added a $_cdrom option for runtime configuration of the CD-ROM device. * Added an internal *CDEX style CD-ROM driver, activated using LREDIR, for use with CD-ROMs that are mounted in Linux. The default autoexec.bat uses this to set drive E: to a CD-ROM. * Implemented support for Unicode fonts for $_X_font, so you can for instance use the univga font or $_X_font="-Misc-Fixed-Medium-R-SemiCondensed--13-120-75-75-C-60-ISO10646-1" * Use $_lpt1, $_lpt2, and $_lpt3 for printer configuration. * The SDL plugin now supports text copy and paste, and X fonts. * It is now possible to point $_vbootfloppy, $_floppy_a etc. to directories and boot from them. * Improved real time clock support with a periodic IRQ generator. * Improved PCI emulation on the console, with $_pci=(auto). * Improved the internal XMS driver. * Various DPMI and VGAEMU fixes. * The dosemu script is compatible with the minimal shell dash. * You can now directly see and manipulate DOS file attributes on Lredir'ed Linux-mounted (V)FAT partitions, when using recent 2.6 kernels. * DOSEMU's stack is no longer marked executable which may improve security.

Use "dosemu -t" to force terminal mode. * Everyone, including root, needs to use "dosemu -s" to be able to use direct hardware access. The -s switch automatically uses direct VGA graphics and raw keyboard mode on the Linux console. * Added support for x86-64, by using CPU emulation for V86 mode, running DPMI code natively. * You can reboot the DOSEMU virtual machine using Ctrl-Alt-Del * Added $_time_mode="linux" option to force the DOS clock to sync with the Linux time. * Freed up 4K of UMB space. * The utility unix.com can now execute Linux commands within DOSEMU interactively. * Run-time plugins are used to allow binary distribution without depending on all libraries. * Implemented debug breakpoints for DPMI. * The SDL plugin (-S option) was improved so that it is almost as capable as the X plugin, and provides a safer way to get console graphics, using fbdev. * 16 bpp graphics programs now run in X with 24/32 bpp. * Long File Names are enabled by default. * Many fixes for the outstanding mouse and keyboard problems. * Customized SVGA drivers of Windows 3.11 can now be used instead of the Trident drivers (refer to Section 9.2 of README.txt). * The -dumb switch quietens DOSEMU until the command is executed if a command is given. So "dosemu -dumb dir" gives a directory listing and nothing else. * The default C: drive has changed from ~/dosemu/freedos to ~/.dosemu/drive_c (similar to Wine).

This causes many DPMI applications to work reliably without random crashes (such as Transport Tycoon, Screamer, Vchess). * Implemented LDT virtualization / direct LDT access for DPMI clients. * Many DPMI and PM API translator fixes to support all commercial Borland tools and other protected-mode programs. You may need Linux kernel 2.6.12-rc3 or more recent versions however to get truely reliable DPMI support. * Most of the DPMI 1.0 API and functionality were added. * The redirected drive filesystem code is much faster than before. * Fixed new errors and warnings with GCC 4.0. * It is now possible to use an external XMS driver, such as himem.sys. * Added the "INT 15h" PS/2 mouse interface. * I/O ports are "fast" by default. * Added some support for sound recording. * The floppy is much faster with 2.6 kernels. * Added support for 2.88M floppies * The printer code now uses line buffering so that you do not have to wait $_printer_timeout seconds before printing starts. * TTY locking can be disabled by $_ttylocks="" * IPX and Packet Driver code was seriously reworked. * The reliability and performance of the serial ports emulation are much improved. * Terminal improvements: - UTF-8 terminals are supported if you use SLang 2 or a UTF-8 patched SLang 1 library. The supplied SLang library subset is no longer necessary and no longer provided. - $_term_char_set no longer exists; $_external_char_set now defaults to the current locale. - Even on non UTF-8 terminals many line drawing characters can now be used, and on the Linux console almost the full CP437 character set. - Many ctrl, alt, shift combinations with function keys, arrow keys, etc, can now be used in xterm and friends. - VGA hardware is emulated in terminal mode as well as in X mode. * Console improvements: - VESA driver added which should be compatible with most BIOSes. This is the default. - Linear frame buffers now work. - Improved behaviour in conjunction with framebuffer consoles. * X improvements: - Added extra X fonts (thanks to Martin Reuber) - The X aspect ratio is no longer set to 4:3 by default, but an integer multiple of the real resolution. - Much improved keyboard layout autodetection - Fixed a grave bug which caused the keyboard not to work properly in some games. - A graphical mouse cursor now works under X with mouse grab enabled. - Added keyboard grab, hardcoded to Ctrl-Alt-k for now. * Added experimental SDL plugin. Mostly functional; makes it possible to run DOSEMU on all supported SDL backends.

It is now possible to use the 32bit Borland tools under dosemu. * Support for the HX DOS Extender was added. It is now possible to run some win32 console apps under dosemu, using that extender. * The Blinker extender is now fully supported (all known versions). But some older versions of that extender may require the 2.4.x linux kernel (linux-2.6.8 will include the necessary fix). * Improved DPMI uncommitted memory support (started in 1.3.0). * The hogtheshold code was reorganized to be able to pass through certain events quicker (such as loading a file in FreeDOS EDIT) even when you have it set to "1". * Fixed all new warnings with GCC 3.4. * Fixed compilation problem with Fedora Core 2 headers. * Added cp895 and bg-mik character set support. * Many VGAEMU bugs were fixed, and bitmap fonts are much quicker. * Allow "fast" i/o ports above 0x400 for kernels that support it (2.6.7-mm kernels only for now) * Implemented VxD hooks for WinOS2: seems to solve all remaining problems with Win3.1(WinOS2): allows Alt-Tab and the timer. * Many DPMI and DOS extender fixes. * An automatic backtrace using GDB (output in ~/.dosemu/boot.log) is attempted when DOSEMU crashes. * Serial code fixes. * Corrected int15/ax=e801 for so $_xms > 64M is reported correctly by MEM. * Fix NPTL issues when switching VC's on the console. * Check /proc/net/ipx/route etc for kernel 2.6.x. * LFN (long file name) fixes. Still needs more testing * Fixed read/write problem for files with negative file offsets on lredir'ed drives.
