JBlaster is a software driver that allows you to configure Altera's PLDs and FPGAs through the ByteBlasterMV in JTAG mode under Linux and Windows NT, interfaceing via the parallel port. The JBlaster parses a Quartus II generated chain description.
jblaster takes a Chain Description File (cdf) as input, and parses the jtag chain information and location of the rbf files. The author adjusted the jblaster parser not to discard the case of path and filenames. As well fixed the parser to directly read Quartus(TM) generated cdf files. You still have to change your filename in rbf.
