Extended System Configuration Data

Extended System Configuration Data

ESCD (Extended System Configuration Data) — специальная таблица, хранящаяся в CMOS, предназначенная для распределения аппаратных ресурсов компьютера.

Эта таблица заполняется в момент первого включения компьютера после изменения его конфигурации. Она значительно упрощает процесс распределения ресурсов при включении или перезагрузке.

На некоторых материнских платах имеется функция защиты от перезаписи Flash-памяти, которая препятствует изменению ESCD при установке нового оборудования, однако эта функция легко отключается при помощи специальных перемычек на материнской плате либо в настройках BIOS.
