Okay,
so Pin 46 on the Maverick goes to JP3.
This pin is labeled PE[1/0]BOOTSEL[1]
it is described as GPIO Port E / Boot Mode Select
Pin 155 on the Maverick goes to JP2
Pin 155 is labeled nMEDCHG/nBROM
it is described as media change interrupt input / internal ROM boot enable
JP1 pin 1 goes to pin 4 of the cd4011BCM
JP1 pin 2 goes to pin 21 of the Xilinx 5032 chip (labeled as I/O-B12
JP1 pin 3 goes to ground
CD4011BCM
Quad 2-Input NOR Buffered B Series Gate . Quad 2-Input NAND Buffered B Series Gate
http://www.alldatasheet.co.kr/datasheet-pdf/pdf_kor/FAIRCHILD/CD4011BCM.htmlThe output of the CD4011BCM on Pin 6 goes to Pin 40 on the Winbond W78E516BP-40 which is labeled AD3 - P03 (this is also connected to a resistor it appears labeled 273 I THINK! its hard to read though...
