B. Card Addressing
The card address is set by installing appropriate jumper pairs
on JP2, pins 1 thru 13, as shown in Fig. 3. An installed jumper
for a given address bit sets the bit to 1 (true) and an uninstalled
jumper sets the bit equal to 0 (false).
Addresses A15 thru A10 (JP2-1 thru 11) are jumper selectable
for defining the base address of the card from 0000H to FC00H
on integral 10H boundaries, where H denotes a hexadecimal
number. Examples are as follow:
Example 1. Set a base address of 0000H.
No jumpers are installed for JP2-1 thru 11.
Example 2. Set a base address of 3800H.
Intall jumpers JP2-5, JP2-7 and JP2-9.
Jumper JP2-13 is used to select the port addresses of the
primary and secondary UARTs, respectively. The card addresses
for these selections are given in Table I. It should be noted that
for a base address of zero, the addresses of the UARTs are the
standard serial port addresses for the IBM PC.
CAUTION: Make sure that the addresses you select for the
MSI-P602 are not in conflict with the serial ports of your CPU
card. For example, if your CPU uses COM1 and/or COM2,
