The original DPS PAR software uses some special manufacturer IDs (most of the companies are ofcourse out of business today) for several harddisks and modells up to 4GB. Except for patching the software and changing the strings normally you won´t have a chance to use some different drives and especially CF cards! Too bad I have lost the sources some years ago but there should/could be a version 2.70 (AFAIR) somewhere in the WWW without the manufacturer restrictions but still limited to 4GB due to its HW firmware (old Z80 asm code...).
Another solution could be using ADPro and NECOS but the last one wouldnt be anything easier to find........
