Same as -noautoexec, but adds config. Uses the scaler specified by "scaler". See the DOSBox configuration file for the available scalers. Similar to the -scaler parameter, but tries to force usage of the specified scaler even if it might not fit. You can specify this command more than once. In this case it will move to second program if the first one fails to start.
See Section 9: "Serial Multiplayer feature. Other people should be able to use escaped double quotes inside the double quotes.
To get a list of the internal commands type "HELP" at the prompt. Sets the amount of free space available on a drive in megabytes regular drives or kilobytes floppy drives. This is a simpler version of -size. Sets the name of the drive to "drivelabel". For Windows: label is extracted from "Real Drive". If you do specify a label, this label will be kept as long as the drive is mounted.
It will not be updated!! Forces use of the aspi layer. Forces use of ioctl commands. Valid on all systems, under windows the -noioctl switch has to be present to make use of the -usecd switch. Enables to select the drive that should be used by SDL. See the information at the -usecd entry above. The same is true for mounting the root of any other drive, except for CD-ROMs due to their read-only nature. Otherwise if you or DOSBox make a mistake you may lose all your files.
You should always install your game inside DOSBox. So if you have the game on CD you always even after installation! MOUNT also works with images but only if you use external program, for example both are free :. It can save the current settings and language strings to disk. Information about all possible sections and properties can be found in Section "The configuration options file".
Write the current configuration settings to a file in a specified location. The configuration file controls various settings of DOSBox: the amount of emulated memory, the emulated sound cards and many more things. BAT as well. See Section "The configuration options file" for more information. Write the current language settings to a file in a specified location. The language file controls all visible output of the internal commands and the internal DOS. See Section "The Language File" for more information.
Switches DOSBox to a more secure mode. It's not possible either to create a new configfile or languagefile in this mode. Warning: you can only undo this mode by restarting DOSBox. This can be used to store the value when using batch files. Both "-set" and "-get" work from batch files and can be used to set up your own preferences for each game. Although it may be easier to use separate DOSBox's configuration files for each game instead.
Program to reduce the amount of available conventional memory. Useful for old programs which don't expect much memory to be free.

They are used to briefly document the effect of each option. To write out ALL options, use command 'config -all' with -wc or -writeconf options.
Possible values: true, false, debug, normal, warn, error, fatal, never. Press ALT-Enter to go back. It can reduce screen flickering, but it can also result in a slow DOSBox. If you end up with small window on a large screen, try an output different from surface. Possible values: surface, overlay, opengl, openglnb, openglhq, ddraw. Possible values: lowest, lower, normal, higher, highest, pause. Resetmapper only works with the default value. Set to -1 to use default, 0 to disable. Default off.
Enable this option -1 or nonzero if you are running a game or. Recommended values -1, 0 to For build engine games, use more memory than in the list above so it can. If cleared, these areas are allocated dynamically which may improve available memory and emulation accuracy.
When clear, unused adapter ROM is mapped out. This does not affect the environment block of sub-processes spawned from the shell. This option has no effect unless dynamic kernel allocation is enabled. This area contains private memory structures used by the DOS kernel.
It is discarded when you boot into another OS. Testing shows that it is possible. SYS does. If it goes by the gate bit alone, it WILL crash. A value of 1us is recommended for ISA bus type delays. If your game. This option will also slightly reduce available. Possible values: off, 1. Possible values: auto, bios, ebda. Set to 0 for automatic assignment.
This value is best left at its default to avoid problems with some games,. There is generally no speed advantage when raising this value. Programs that use protected mode like Windows 3. This value should normally be set to 0. If nonzero, it is added to the memsize parameter. Finer grained control of total memory may be useful in. RAM or early systems with odd extended memory sizes.
Does not affect extended memory. Setting this option to a value in the range can be used to simulate modern BIOSes. You may also play with this option for diagnostic purposes or to stress test DOS programs in limited memory setups. If the software you are.
Note that enabling this option can cause slight performance degredation. You can find instructions on how to use the Change Directory command, in the CD section of the Commands article.
One more step, running the game! Most games have an EXE file in their directory that you can run. Most of the time, the file is in the root folder. Please consult the documentation of your game for which file is needed to start the game. So now, I just type this:. The steps described above are closely aligned with how DOS Based operating systems behave natively.
However modern operating system allow for more user friendly although less authentic ways of playing your favorite games. If the steps above seem tedious or confusing you can try some of these other guides. In most cases these guides will still require you to setup a working DOSBox environment. The program is interpreted instruction by instruction. This approach is a lot more CPU demanding than dynamic core but allows for a more fine-grained time emulation and is needed on platforms for which DOSBox doesn't have a dynamic core.
Basically the same as normal, but optimized for real-mode older games. In case a protected-mode game is started, it automatically switches back to normal core. The program instructions are, in blocks, translated to host processor instructions that execute directly. See also [3]. In the most cases this approach is more efficent than interpretation, except for programs that employ massive self-modifying code. This option is not present on all host platforms.
Real-mode programs are run with the normal core. For protected mode programs it switches to dynamic core, if available. Sets the emulated CPU speed to a fixed amount of cycles nnnn. The game compatibility should be identical to 0. It's recommended to use config -securemode when dealing with untrusted files. Ideally, 0. Thursday, December 13th, - Qbix.
