This is for the external Amacom Bravo 6x CD-ROM drive, hanging off the original Amacom PCMCIA IDE controller card. Note, this driver came from Amacom UK Tech Support, who had me check that the "6x" on the unit was printed in RED, and that the Open/Stop button was BLACK. They may have variants for other models - email them from the support pages on www.amacom-tech.com. (Driver is not listed as a standard download from them.) Worked fine for me after a plain DOS 6.22 install, accepting default IRQ=17, on a Toshiba CT2130CT laptop (486!!). w95 osr2 installed after that from CD, and used it's own drivers from then on.
