intel_vbt_decode

Утилита декодирования дампов видео BIOS графических контроллеров Intel

Синтаксис:

intel_vbt_decode [опции]

Опции:

--file file

Имя файла с дампом видео BIOS, созданного утилитой intel_bios_dumper.

--devid did

PCI идентификатор устройства ($a did) для более точного определения типа графического контроллера. По умолчанию утилита пытается получить эти сведения из дампа, но поскольку видео BIOS может быть общим для нескольких семейств контроллеров, идентификация является приблизительной. Точное определение контроллера позволяет достовернее интерпретировать дамп относительно специфики контроллера.

--all-panels

Позволяет включить отображение сведений обо всех TFT/LCD панелях, определенных в таботцах видео BIOS (VBT, Video BIOS Tables).

--panel-type N

Вывод информации только о панели с номером N.

--hexdump

Выводить информацию о блоках данных BIOS (BDB, BIOS Data Block) в шестнадцатеричной форме.

--block N

Вывод информации только о BDB с номером N.

Платформы:

ЗОСРВ «Нейтрино»

Целевые архитектуры:

Описание:

Утилита предназначена для разбора дамп-файла видео BIOS, формируемого утилитой intel_bios_dumper.
