to its working position in the memory map and to initialize SDRAM to address 0x00000000.
SDRAM
The SDRAM used on the dimmPCITM is the MT48LC4M16A2 or compatible 3.0V SDRAM. The
exact SDRAM part or size is dependant on the current SDRAM in stock or available on the
market. The SDRAM is located at 0x00000000 in memory so that the interrupt vector table will be
located in SDRAM.
* NOTE * Setting the registers to recognize different SDRAM sizes doesn’t work as explained in
the Motorola Application Note AN2148-D rev 5.0. Instead a few jumper resistors select the
SDRAM size.
