# intel\_bios\_reader(1)

Intel Video BIOS Table parser

## NAME

intel\_bios\_reader - Intel Video BIOS Table parser

## SYNOPSIS

**intel\_bios\_reader** \[*OPTIONS*\]

## DESCRIPTION

**intel\_bios\_reader** is a tool to parse the Intel Video BIOS Tables (VBT) and present the information in a human readable format.

The preferred ways of getting the binary VBT to parse are:

- 1\.

  /sys/kernel/debug/dri/0/i915\_vbt (since kernel version 4.5)

- 2\.

  /sys/kernel/debug/dri/0/i915\_opregion

- 3\.

  Using the **[intel\_bios\_dumper(1)](/intel_bios_dumper/1.md)** tool.

The VBT consists of a VBT header, a BIOS Data Block (BDB) header, and a number of BIOS Data Blocks.

## OPTIONS

- **--file=***FILE*

  Parse Video BIOS Tables from FILE.

- **--devid=***DEVID*

  Pretend to be PCI ID DEVID. Some details can be parsed more accurately if the platform is known.

- **--panel-type=***N*

  Parse the details for flat panel N. Usually this is retrieved from the Video BIOS Tables, but this can be used to override.

- **--all-panels**

  Parse the details for all flat panels present in the Video BIOS Tables.

- **--hexdump**

  Hex dump the blocks.

- **--block=***N*

  Dump only the BIOS Data Block number N.
