Functional Architecture Intel® Server Board SE7505VB2 3.3.2.3 Floppy Disk Controller The floppy disk controller (FDC) in the sIO is functionally compatible with floppy disk controllers in the DP8473 and N844077. All FDC functions are integrated into the sIO including analog data separator and 16-byte FIFO. The baseboard provides a standard 34-pin interface for the floppy disk controller. 3.3.2.4 Keyboard and Mouse Two external PS/2 ports, located on the back of the baseboard, are provided to access the keyboard or mouse functions. The two ports are interchangeable and will automatically detect and configure a keyboard or mouse plugged into either port. 3.3.2.5 Wake-up Control The sIO contains functionality that allows various events to control the power-on and power-off the system. 3.3.3 BIOS Flash The board incorporates an Intel® N82802AC (FWH8) flash memory component. The N82802AC is a high-performance 8-megabit memory component that provides 1024K x 8 of BIOS and non- volatile storage space. The flash device is connected through the LPC Bus from the ICH4 from the sIO. 30 Revision 1.2 Intel part number C32194-002
