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 1.3.3 (2005-12-xx) ============= * "dosemu" starts xdosemu by default in X. 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 chapter 9.2 of README).

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.
