asm：dosbox安装及汇编环境配置(win)

一、dosbox安装及汇编环境配置

dosbox的安装以及汇编测试




1、建立文件夹：


	1.1	G:\assemblyWorkspaces\masm_dos
		
		功能1：“汇编依赖文件夹”存放位置：
	
		功能2：dosbox挂载位置（mount c G:\assemblyWorkspaces\masm_dos）
		
		功能3：masm源文件存放位置；G:\assemblyWorkspaces\masm_dos\src。
		
		
	1.2　　D:\tools\asm\masm_dos\dosbox_install
		
		功能：安装dosbox
		



		
2、 dosbox

	2.1 安装dosbox，安装位置：D:\tools\asm\masm_dos\dosbox_install，一直ok到结束
	
	2.2 汇编的工作区的目录：
		2.2.1 汇编工作区根目录：  G:\assemblyWorkspaces\masm_dos
		2.2.2 汇编工作区子目录：  G:\assemblyWorkspaces\masm_dos\src
		
	2.3 dosbox配置：
		2.3.1  dosbox配置位置1：
			--	C:/Users/Administrator/AppData/Local/DOSBox/dosbox-0.74-3.conf
				2.3.1.1	屏幕分辨率配置、字体大小配置：
				2.3.1.2	汇编环境配置：
		2.3.2  dosbox配置文件位置2:
			--	D:\tools\asm\masm_dos\dosbox_install\DOSBox-0.74-3\DOSBox 0.74-3 Options.bat
		2.3.3  双击文件"DOSBox 0.74-3 Options.bat"，在文件末尾添加如下文字：
			“
			# 井号部分的是注释语句，不用写
			
			mount    c  G:\assemblyWorkspaces\masm_dos 　　#把“g:\xx”盘挂载在dosbox的c盘位置。			
			c: 						#启动时，进入dosbox的c盘
			path=c:\;src;		# 配置环境变量：  进入工作区的子目录后，可以使用汇编工具（masm/debug/link/...）
			
			”
		2.3.4	说明：
			2.3.4.1	命令：	mount    “挂载点（c）”		汇编工作区的根目录	
			2.3.4.2 说明：	将“汇编工作区的根目录”挂载在“C盘”；即将“汇编工作区的根目录”当作“C盘”。
			2.3.4.3 实例：	mount    c  G:\assemblyWorkspaces\masm_dos
		
	2.4 将“asm_tools（masm/debug/link/...）”的内容复制到 G:\assemblyWorkspaces\masm_dos 位置；
	
	
	
	
	
3.使用dosbox汇编

	3.1 编写汇编文件，命名为test.asm，保存在 G:\assemblyWorkspaces\masm_dos\src 位置；
	
	3.2 启动dosbox；在dosbox内进行“汇编、链接、执行”等动作。
	
	3.3 汇编（dosbox）： masm test.asm
	
	3.4 链接（dosbox）： link test.obj
	
	3.5 执行（dosbox）:  c:\> test.exe

二、dosbox配置的实例

  1 # This is the configuration file for DOSBox 0.74-3. (Please use the latest version of DOSBox)
  2 # Lines starting with a # are comment lines and are ignored by DOSBox.
  3 # They are used to (briefly) document the effect of each option.
  4 
  5 [sdl]
  6 #       fullscreen: Start dosbox directly in fullscreen. (Press ALT-Enter to go back)
  7 #       fulldouble: Use double buffering in fullscreen. It can reduce screen flickering, but it can also result in a slow DOSBox.
  8 #   fullresolution: What resolution to use for fullscreen: original, desktop or fixed size (e.g. 1024x768).
  9 #                     Using your monitor's native resolution (desktop) with aspect=true might give the best results.
 10 #                     If you end up with small window on a large screen, try an output different from surface.
 11 #                     On Windows 10 with display scaling (Scale and layout) set to a value above 100%, it is recommended
 12 #                     to use a lower full/windowresolution, in order to avoid window size problems.
 13 # windowresolution: Scale the window to this size IF the output device supports hardware scaling.
 14 #                     (output=surface does not!)
 15 #           output: What video system to use for output.
 16 #                   Possible values: surface, overlay, opengl, openglnb, ddraw.
 17 #         autolock: Mouse will automatically lock, if you click on the screen. (Press CTRL-F10 to unlock)
 18 #      sensitivity: Mouse sensitivity.
 19 #      waitonerror: Wait before closing the console if dosbox has an error.
 20 #         priority: Priority levels for dosbox. Second entry behind the comma is for when dosbox is not focused/minimized.
 21 #                     pause is only valid for the second entry.
 22 #                   Possible values: lowest, lower, normal, higher, highest, pause.
 23 #       mapperfile: File used to load/save the key/event mappings from. Resetmapper only works with the defaul value.
 24 #     usescancodes: Avoid usage of symkeys, might not work on all operating systems.

 57 # captures: Directory where things like wave, midi, screenshot get captured.
 58 #  memsize: Amount of memory DOSBox has in megabytes.
 59 #             This value is best left at its default to avoid problems with some games,
 60 #             though few games might require a higher value.
 61 #             There is generally no speed advantage when raising this value.

 67 
 68 [render]
 69 # frameskip: How many frames DOSBox skips before drawing one.
 70 #    aspect: Do aspect correction, if your output method doesn't support scaling this can slow things down!
 71 #    scaler: Scaler used to enlarge/enhance low resolution modes. If 'forced' is appended,
 72 #              then the scaler will be used even if the result might not be desired.
 73 #              To fit a scaler in the resolution used at full screen may require a border or side bars,
 74 #              to fill the screen entirely, depending on your hardware, a different scaler/fullresolution might work.
 75 #            Possible values: none, normal2x, normal3x, advmame2x, advmame3x, advinterp2x, advinterp3x, hq2x, hq3x, 2xsai, super2xsai, supereagle, tv2x, tv3x, rgb2x, rgb3x, scan2x, scan3x.

 87 #    cycles: Amount of instructions DOSBox tries to emulate each millisecond.
 88 #            Setting this value too high results in sound dropouts and lags.
 89 #            Cycles can be set in 3 ways:
 90 #              'auto'          tries to guess what a game needs.
 91 #                              It usually works, but can fail for certain games.
 92 #              'fixed #number' will set a fixed amount of cycles. This is what you usually
 93 #                              need if 'auto' fails. (Example: fixed 4000).
 94 #              'max'           will allocate as much cycles as your computer is able to
 95 #                              handle.
 96 #            Possible values: auto, fixed, max.
 97 #   cycleup: Amount of cycles to decrease/increase with keycombos.(CTRL-F11/CTRL-F12)

111 #            Possible values: 1024, 2048, 4096, 8192, 512, 256.
