CEC Chip Initialization (CINI)
‘F7A0’x through ‘F7FF’x
The CINI component initializes the chips in the system unit, based on the system configuration. These actions include configuring system memory and address ranges, chip modes, and communicating from chip to chip. CINI also determines and sets the processor and bus frequencies.
Какие CCIN и p/n на старой памяти и какие опознавательные аналоги на новой?
