Works with Windows NT, 3.11 also. Actually, it's an executable EXE for installing drivers needed for external ATAPI CD-ROM devices. It includes version 1.41 of the Epatap9x.mdp driver. It should work with other external CD drives. (MP6200A is one I know of.) Works beautifully with Adaptec's Easy-CD version 2.5d and DirectCD version 3.5c. Just run the EXE file and follow instructions. Beautiful connection interface! Found while trying to solve an APM problem with my HP7500e CD-drive. Page fault (0E) at 28 c29d59d9 in VXD epatap9x(01) + 00004f39 if I have any kind of CD (CD-R, CD-RW, CD-ROM,) in the drive when stand-by (suspend) time comes!!!. Any ideas? I guess Shuttle Technologies is different from Shuttle Computers, am I wrong?
