sockets IC6 and IC7 on the memory daughterboard according to their
labels. Attention should be paid to the correct orientation of these
ROMs during installation.</P

>The GDB stub allows communication with GDB using the serial
port (channel C) at connector PJ1. The communication parameters
are fixed at 38400 baud, 8 data bits, no parity bit, and 1 stop
bit (8-N-1). No handshaking is employed. Connection to the host
computer should be made using an RS232C null modem cable.</P

>CygMon and eCos currently provide support for a 16Mbyte 60ns
72pin DRAM SIMM fitted to the PJ21 connector. Different size DRAMs
may require changes in the value stored in the DCCR0 register. This
