80x86(DOS)虚拟机

DOSBox v0.65 ===== NOTE: ===== While we are hoping that one day, DOSBox will run all programs ever made for the PC, we are not there yet. At present, DOSBox running on a high-end machine will roughly be the equivalent of a 486 PC. The 0.60 release has added support for "protected mode" allowing for more complex and recent programs, but note that this support is still in an early stage of development and unlike the support for 386 real-mode games (or earlier) hasn't been completed yet. Also note that "protected mode" games need substantially more resources and may require a much faster processor for you to run them properly in DOSBox. ====== INDEX: ====== 1. Quickstart 2. FAQ 3.

FAQ: ======= Some Frequently Asked Questions: Q: I've got a Z instead of a C at the prompt. Q: My game crashes when using opengl/nb or is much slower. Q: My CD-ROM doesn't work. Q: The mouse doesn't work. Q: The sound stutters or sounds stretched/weird. Q: I can't type \ or : in DOSBox. Q: The game/application can't find its CD-ROM. Q: The game/application runs much too slow! Q: I would like to change the memory size/cpu speed/ems/soundblaster IRQ. Q: What sound hardware does DOSBox presently emulate? Q: DOSBox crashes on startup and I'm running arts Q: Great README, but I still don't get it. Q: I've got a Z instead of a C at the prompt. A: You have to make your directories available as drives in DOSBox by using the "mount" command. For example, in Windows "mount C D:\GAMES" will give you a C drive in DOSBox which points to your Windows D:\GAMES directory. In Linux, "mount c /home/username" will give you a C drive in DOSBox which points to /home/username in Linux. Q: My game crashes when using opengl/nb or is much slower. A: Somehow our opengl code isn't entirely stable on some platforms. Use surface instead. Q: My CD-ROM doesn't work. A: To mount your CD-ROM in DOSBox you have to specify some additional options when mounting the CD-ROM. To enable the most basic CD-ROM support: - mount d f:\ -t cdrom To enable low-level SDL-support: - mount d f:\ -t cdrom -usecd 0 To enable low-level ioctl-support(win2k/xp/linux): - mount d f:\ -t cdrom -usecd 0 -ioctl To enable low-level aspi-support (win98 with aspi-layer installed): - mount d f:\ -t cdrom -usecd 0 -apsi In the commands: - d driveletter you will get in DOSBox - f:\ location of cdrom on your PC. - 0 The number of the CD-ROM drive, reported by mount -cd See also the question: The game/application can't find its CD-ROM. Q: The mouse doesn't work. A: Usually, DOSBox detects when a game uses mouse control. When you click on the screen it should get locked (confined to the DOSBox window) and work. With certain games, the DOSBox mouse detection doesn't work. In that case you will have to lock the mouse manually by pressing CTRL-F10. Q: The sound stutters or sounds stretched/weird. A: You're using too much cpu power to keep DOSBox running at the current speed. You can lower the cycles, skip frames or get a faster machine. You can also increase the prebuffer in the configfile. Q: I can't type \ or : in DOSBox. A: This is a known problem. It only occurs if your keyboard layout isn't US. Some possible fixes: 1. Switch your keyboard layout. 2. Use / instead. 3. Open dosbox.conf and change usescancodes=false to usescancodes=true. 4. Add the commands you want to execute to the "configfile". 5. Start the keymapper (CTRL-F1 or add -startmapper switch to DOSBox). 6. Use ALT-58 for : and ALT-92 for \. 7. for \ try the keys around "enter". For ":" try shift and the keys between "enter" and "l" (US keyboard layout). 8. Use keyb.com from FreeDOS (http://projects.freedos.net/keyb/). Q: The game/application can't find its CD-ROM. A: Be sure to mount the CD-ROM with -t cdrom switch. Also try adding the correct label (-label LABEL). To enable more low-level CD-ROM support, add the following switch to mount: -usecd #, where # is the number of your CD-ROM drive reported by mount -cd. If you run Win32 you can specify -ioctl or -aspi. Look at the description elsewhere in this document for their meaning. Q: The game/application runs much too slow! A: Look at the section "To run resource-demanding games" for more information. Q: I would like to change the memory size/cpu speed/ems/soundblaster IRQ. A: This is possible! Just create a config file: config -writeconf configfile . Start your favourite editor and look at all the settings present. To start DOSBox with your new settings: dosbox -conf configfile Q: What sound hardware does DOSBox presently emulate? A: DOSBox emulates several legacy sound devices: - Internal PC speaker This emulation includes both the tone generator and several forms of digital sound output through the internal speaker. - Creative CMS/Gameblaster The is the first card released by Creative Labs(R). The default configuration places it on port 0x220. It should be noted that enabling this with the Adlib emulation may result in conflicts. - Tandy 3 voice The emulation of this sound hardware is complete with the exception of the noise channel. The noise channel is not very well documented and as such is only a best guess as to the sound's accuracy. - Adlib Borrowed from MAME, this emulation is almost perfect and includes the Adlib's ability to almost play digitized sound. - SoundBlaster 16/ SoundBlaster Pro I & II /SoundBlaster I & II By default DOSBox provides Soundblaster 16 level 16-bit stereo sound. You can select a different SoundBlaster version in the configfile of DOSBox (See Internal Commands: CONFIG). - Disney Soundsource Using the printer port, this sound device outputs digital sound only. - Gravis Ultrasound The emulation of this hardware is nearly complete, though the MIDI capabilities have been left out, since an MPU-401 has been emulated in other code. - MPU-401 A MIDI passthrough interface is also emulated. This method of sound output will only work when used with a General Midi or MT-32 device. Q: DOSBox crashes on startup and I'm running arts. A: This isn't really a DOSBox problem, but the solution is to set the environment variable SDL_AUDIODRIVER to alsa or oss. Q: Great README, but I still don't get it. A: While unlikely, this seems to happen. A look at "The Newbie's pictorial guide to DOSBox" located at http://vogons.zetafleet.com/viewforum.php?f=39 might help you.

Usage: ========= An overview of the command line options you can give to DOSBox. Windows Users must open cmd.exe or command.com or edit the shortcut to DOSBox.exe for this. The options are valid for all operating systems unless noted in the option description: dosbox [name] [-exit] [-c command] [-fullscreen] [-conf congfigfile] [-lang languagefile] [-machine machinetype] [-noconsole] [-startmapper] [-noautoexec] dosbox -version name If "name" is a directory it will mount that as the C: drive. If "name"
