What is a DSDT

DSDT (Differentiated System Description Table) is a part of the ACPI specification. It supplies information about supported power events in a given system. ACPI tables are provided in firmware from the manufacturer.

Ours are compiled with the Microsoft compiler. RT2 location: Address : 0xFDEFD000 Length : 15469 (NVIDIA T114EDK2)
