I have an IBM 560e Think Pad laptop, I put windows 3.1 on it because it didn't have a cd-rom driver.. I have located an external cd-rom drive but i don't know what to do from now. It is sony CSD-7611. and it has a Linksys Parallel to SCSI converter on it. I don't have any drivers for it and i don't know where to get them. So far i have installed a SCSI Driver and got mscedx.exe in a file that says bin. and a fdcd.sys file in a file that says dev

This can be a huge pain in the xxx, or not, depending.

Is it possible that drive just isn't supported in DOS mode? I'm not familiar with it.

I'm assuming you can't find specific DOS drivers for the thing.

I've got an old Panasonic KXL-d740, and you can find drivers for it that will directly access the drive in DOS

Have you tried the "card and socket services" route?

is some light reading on what a pain PCMCIA can be

Then, there's this:

which says in part:

"This Document will refer to ThinkPad systems in three generic categories:
A. Legacy systems - These include the older systems which use the "generic" PC Card Director software for DOS/WIN and OS/2 (currently PCTPX130 or PC36Bxxx from the BBS), and the built in, default support included with Windows 95. Examples are the 75X, 360, 365(C and E series), 701, and similar.
B. Current ThinkPads - This includes those which use the PCTPG series of PCMCIA drivers for all operating systems. This includes all 760 models, as well as the 560 and 365X machines.
C. ThinkPad 380 which uses System Soft Card Wizard software to support cards in Windows 3.x and 95. OS/2 PCMCIA support is still provided via PC Card Director on this system."

I did a search for your CDROM at driverguide and got no results AT ALL
