Solution:

The POS-102 is a special slot interface called "PISA". The golden finger contains both ISA and PCI bus. For the female PISA slot can plug in ISA card directly because the shallower layer is pure ISA pins. The deeper layer of the PISA slot is the PCI pins, therefore you cannot directly plug PCI card directly into the female PISA solt because it will short the shalow ISA pins and will be burnt. On the other hand, as you plug in ISA card, the ISA golden finger is not deep enougth to reach PCI so it will only use shallow ISA pins and works fine. As you plug in POS-102 riser card, its PISA is in special lay out, it's golden finger contains both ISA and PCI layers to reach those pins. So the riser card can provide ISA and PCI slot signals. There are some jumper on the POS-102. the address and IRQ should be taken care of. The jumper on POS-560 is to set PCI interfrace IRQ (A, B,..etc) and Address. It need to match the setting in the BIOS of CPU boards. We already pre-set the default setting of POS-102 to work with POS-560, therefore you don't have to change the setting yourself. In order to solve PCI card detaction prolem, please refer to the following action. (1) Check if the IRQ and I/O address of the add-on PCI card is conflict with system. Or, you can change the IRQ or I/O address and then try again. (2) Use a ISA card (e.g. VGA card, sound card...etc) to test if the PCI/ISA expansion bus is OK. If the PCI/ISA slot is OK, but your PCI card still can not work. Maybe your PCI card is not compatible with POS-560. I suggest you to use another card with the same function.
