This ZIP file consists of 2 different files inside so you'll have to "explode" it first, then go from there both files are necessary to make this model of drive work correctly (they are the "native" drivers from the manufacturer, by the way). The order of the files in CONFIG.SYS is crucial, but you still need to read both "README.TXT" files to get the arguments and what-not correct, also. The file on the 1st line should be ATAPIMGR.SYS and the 2nd immediately under it on the next line should be SR_ASPI.SYS /CD01 or whatever your CD-RW drive designation is. Again, pay close attention to the README.TXT from *BOTH* master files, or you'll hang-up during boot-up every time. Hope that helps!
