Анализ ошибок компьютера диагностической картой (POST-карта)
Введение
Карта называется POST (Power On Self Test - карта самотестирования). Отображает коды ошибок, при невозможности загрузки операционной системы или нет изображения на экране или нет звуков BIOS.
Когда питание подано, BIOS проводит точный тест схемы, памяти, клавиатуры, видеокарты, жёсткого диска, затем анализирует системную конфигурацию. После инициализации базовой системы ввода/вывода идёт загрузка операционной системы.
Диагностическая карта не будет отображать данные в следующих случаях:
1. Карта вставлена в материнскую плату без центрального процессора.
2. Когда горит диод RST LED.
1. Карта вставлена в материнскую плату без центрального процессора.
2. Когда горит диод RST LED.
Общее описание POST карты
Описание светящихся диодов:
RUN | Мерцание | Если светодиод горит, материнская плата включена, не имеет значения какие коды проходят |
CLK | BUS CLOCK | Горит когда питание подано на материнскую плату (обычно без процессора) |
BIOS | Считывание BIOS | Светодиод включается и выключается когда подаётся питание на материнскую плату, при чтении BIOS процессором |
IRDY | Менеджер готов | Светодиод включается и выключается когда есть сообщение |
OSC | Мигание | Загорается когда подано питание на материнскую плату, или если нет то кристалл колебательного контура сломан |
FRAME | Период кадра | Горит всё время. Включается и выключается когда есть сообщение |
RST | Reset | Загорается на пол секунды, когда нажимаете на кнопку включения или сброса. Если горит питание, то стоит проверить RESET (замыкает или сломан). |
12V | Power | Загорается единожды при включении, подаче питания, если не загорается это означает короткое замыкание на материнской плате или нет 12В. |
-12V | Питание | Тоже самое что и "12V" |
5V | Питание | Тоже самое что и "12V" |
-5V | Питание | Тоже самое что и "12V" (-5V только для ISA слота) |
3V3 | Питание | Загорается при подаче питания (только PCI), где есть 3,3В. Если нет на материнской плате дежурного напряжения 3,3В - не загорается |
