在实模式、大模式下编译uC/OS_ii
在Borland C++6 中的c语言项目中加入OS_CPU_A.ASM文件，编译后报错如下：
[Linker Fatal Error] Fatal: Unsupported 16-bit segment(s) in module H:/SOFTWARE/uCOS/Ix86L/BC45/OS_CPU_A.ASM
估计是由于OS_CPU_A.ASM文件中的命令为16位的，无法和Borland C++6编译的32位的程序兼容造成的；但是如何才能解决这个问题呢？？？
Borland C/C++ V4.51(Borland Turbo C++ 4.5)是否为16位的，在哪里能得到？？？
下面是OS_CPU_A.ASM文件，如何才能编译通过？请诸位大虾指教！！

汇编呀?看晕了.如果不是做驱动程序,还是不用汇编的好.曾用汇编写了一个图像合并的代码,花了很多时间,结果没比pascal快多少,也就一点点吧.
 
在Win32下不支持SEG伪指令,因为win32是运行在flat模式下的.

MOV DS, AX
问题就出在上面那两行,删除掉
