# Appendix C Sample Driver INF Files

The following INF file example are from EDK II `MdeModulePkg/Universal/Disk/DiskIoDxe/DiskIoDxe.inf` and `IntelFrameworkModulePkg/Universal/StatusCode/RuntimeDxe/StatusCodeRuntimeDxe.inf` driver modules.

## C.1 DiskIoDxe INF file

```
## @file
# Module that lays Disk I/O protocol on every Block I/O protocol.
#
# This module produces Disk I/O protocol to abstract the block accesses
# of the Block I/O protocol to a more general offset-length protocol
# to provide byte-oriented access to block media. It adds this protocol
# to any Block I/O interface that appears in the system that does not
# already have a Disk I/O protocol. File systems and other disk access
# code utilize the Disk I/O protocol.

# 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://lersek.gitbook.io/laszlo-s-fork-of-the-edk-ii-module-information-inf/pkgs_order/appendix_c_sample_driver_inf_files.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.
