Bulky job with blue top and transparent bottom? Flaky bit of kit. Getting on a bit.
From my notes at the time, installation on Win 98 was in two stages.
1. USB to SSFDC Class driver in File DFMPD01.INF. 1KB dated 2 Feb 00.
2. (USB to IDE/ATAPI using OEI-link) USB to IDE Media Reader Miniport Driver also in DFMPD01INF (Other Devices).
I don't normally make such detailed (and incomprehensible

) notes so you will gather that at the time I bought this bit of kit I had problems too.
These files are the same as on my installation disk. I'll happily e-mail them to you need if you wish. Win 98 won't do P 'n P. Put the files in a folder somewhere and do "Add New Hardware"
before you plug in the reader.
Send me an e-mail address if I can help.
PS, you are on Win 98 Second Edition, I hope!
