最近看了傅琳琳的那篇OAL的点点滴滴(http://www.vckbase.com/document/viewdoc/?id=1379)，他告诉我StartUp（）函数是CE启动的第一个函数，可是我硬是没有搜索到那个什么鬼函数在哪里，在MSDN帮助文档里面也说：

This function is the first function to be called when the OS is booted from either the boot loader or reset vector.

void StartUp(void);

Parameters

None.

Return Values

None.

Remarks

This function is the first function called during boot up. The function needs to initialize the CPU to a known state and then call one of the kernel initialization functions, either KernelInitialize or KernelStart.

可是我为什么找不到呢？

嘿嘿，在一阵子搜索之后，我放弃了，然后开始翻启动代码那段汇编语言，看到一个词语不认识：LEAF_ENTRY ，查看MSDN的帮助文档说，

This macro declares the beginning of a routine that does not require any prolog code.

LEAF_ENTRY Name[,
[Section=]SectionName]

Parameters

Name

Name is the routine name and is in the global name space.

SectionName

SectionName is the name of the section in which the entry will appear; it is optional and defaults to .text.

Return Values

None.

Remarks

A LEAF_ENTRY must have an associated ENTRY_END.

Each supported microprocessor contains a definition for this macro in a microprocessor-specific header file. The following table shows the supported microprocessor families and the related header file that contains the macro definition for that family.
