HARDWARE CONFIGURATION
Hardware setup jumper positions assume that the 4I61 card is oriented in an
upright position, that is, with the PC/104 connectors towards the person doing the
configuration, and the on card writing right-side-up.
The 4I61 card must be assigned a slot number before use. In desktop PCI
system the slot number is determined by the physical slot that the PCI card is inserted
into. In PC104-PLUS systems, all signals on the bus are the same for each card, so a
method is needed to differentiate each card. This is done with the slot number
jumpers the 4I61 card. 2 jumpers. W3 and W4 determine the 4I61 slot assignment.
The following table shown the jumper settings:
W3 W4 SLOT IRQ REQ/GNT NOTES
DOWN DOWN 0 A 0 DEFAULT
DOWN UP 1 B 1
UP DOWN 2 C 2
UP UP 3 D 2 SHARES SL2 RQ/GNT
The 4I61 can accommodate a boot EPROM or Flash EEPROM. Socket U6 is
provided for the EPROM or flash EEPROM. The 4I61 will only support 3.3V ,32 pin
EPROM and Flash EEPROMs.
The hexadecimal MAC address is printed on a label on the front edge of the
PC/104 connector of the 4I61 card.
