Page 4: ... limits the amount of current an x1 card can draw from the 12 V rail to 500 mA Since the 12 V rail on the EVM is used solely for providing bus power to attached 1394 devices it is possible that 2 attached devices may exceed this requirement If testing is desired with devices that exceed this limit the board may be altered to provide power through a standard 4 pin floppy connector which will be abl...

Page 5: ...IOS The XIO2200 requires a memory window in order to access some registers used by the device If Microsoft determines that the BIOS failed to assign a memory window to the XIO2200 it will assume that one can not be assigned and that the device is non functional In this situation the OS will not enumerate devices behind the bus and they will never be configured or assigned resources This failure ca...

Page 6: ... 4 2 Check if Bridge is link training If the system does not boot detach all 1394 peripherals from EVM and try again If system is hanging before OS loads then it is likely that the system and the EVM are having difficulty completing link training which is most likely an issue with signal integrity on the differential pairs If a PCI Express analyzer is unavailable then try a different express slot ...
