请问：有关int86()函数具体调用问题(50分)

[]先拿个例子来看：
int MouseReset(void)
{
union REGS in,out;
in.x.ax=0;
int86(0x33,&in,&out);
if (out.x.ax==0) return 0;
return 1;
}
上面的例子是有关鼠标中断调用的函数
0x33 是鼠标中断的中断号
in 调用鼠标中断的入口参数
out 调用鼠标中断的出口参数（保存中断过程的返回值）
好了，双面函数分析的差不多了，俺要提出问题了：
1、计算机中队应的软硬中断有很多，我在使用不同的中断时，它的入口参数值不可能是同一个值，
例如：in.x.ax=0 ，那么，我在调用不同的中断时（如显示中断），入口参数到底应赋给什么值，
另外，我知道入口参数应赋给寄存器，可是我到底付给哪一个寄存器呢，我百思不得其解，逼得我
看了一便汇编，基本了解各个寄存器的功能，可是我还是不知入口参数到底赋何值，到底赋给哪个
寄存器，后来我考虑可能针对每个中断都有一张表，其中说明了这个中断的具体调用方法（使用哪个
寄存器，值应该是多少等等），那么，是不是这样呢，请高手给予帮助，不胜感激！！！
2、还有，就是返回值。调用一个中断，都会有返回值，根据返回值就可了解中断调用是否正常，那么，
返回值到底赋给那个寄存器呢？？？？？？
大哥，帮帮忙吧，我真的不知该怎么做了，急切盼望您的回信 ：）

你那是Dos时代的程序。我当年也搞过。
在Windows中你就别想了

我记的你好像问同样的一个问题。
其实你只要找一下中断列表，啥都明白了，这个资料网上多的是。
下面是我给你找的

下面是我给你的调用例子，其它的由于太多，你自己找找吧。

INT 33,0 - Mouse Reset/Get Mouse Installed Flag

AX = 00


on return:
AX = 0000 mouse driver not installed
FFFF mouse driver installed
BX = number of buttons


- resets mouse to default driver values:

. mouse is positioned to screen center
. mouse cursor is reset and hidden
. no interrupts are enabled (mask = 0)
. double speed threshold set to 64 mickeys per second
. horizontal mickey to pixel ratio (8 to 8)
. vertical mickey to pixel ratio (16 to 8)
. max width and height are set to maximum for video mode

INT 33,1 - Show Mouse Cursor


AX = 01


returns nothing


- increments the cursor flag; the cursor is displayed if flag
is zero; default flag value is -1



其它的调用与此类似，希望上面这些对你有用。
