There are many reasons for this, including: • The system cannot initialize the AML interpreter. • The system cannot find the Root System Description table. • The system cannot allocate a critical driver. • The system cannot load the Root System Description table. • The system cannot load device descriptor blocks. • The system cannot connect an interrupt vector. • The SCI_EN (system control interrupt enable request) cannot be set (see 0x00000001). • The ACPI Table checksum is incorrect. ACPI is a hierarchical arrangement of tables, each one building upon the next to define the complete capabilities of the system and of every device in the system. ACPI starts by looking for the Root System Description table, which points to the next table, which points to the next table, and so on. Usually, the 0x000000011 error occurs because these tables are damaged or missing.------------------------------------------------------Altceva nu apare chiar daca scot discul.
