# bzImage的全貌

在[启动镜像bzImage的前世今生](/kernel-exploring/00_index/07_rules_for_bzimage.md)我们看到bzImage由setup.bin和vmlinux.bin两部分组成。

经过对这两部分的探索后，将整体展开在一起。希望有一个比较清晰的全景。

                    \       /
               arch/x86/boot/bzImage
```

其中几个链接脚本具体是：

* vmlinux.lds.S -> arch/x86/kernel/vmlinux.lds.S
* setup.ld -> arch/x86/boot/setup.ld
* vmlinux.lds -> arch/x86/boot/compressed/vmlinux.lds

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://richardweiyang-2.gitbook.io/kernel-exploring/00_index/14_bzimage_whole_picture.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
