Well, if you can't get the IBM downloaded file to work, I don't know what to tell you. a few questions.
Did you read the page carefully from where you downloaded the file? Most of thes files GENERATE an install disc, that means you do not copy the file you downloaded directly to a floppy, in most cases you download the file to your hd, RUN the file from the hd, and it GENERATES an install floppy for whatever component you are dealing with.
In other words, an install floppy for video, sound, cd, whatever.
I'd try and find a friend's computer and re-download it, who knows what glitch there may be.

Above is the page for the "file matrix" for your machine.
(select Cdrom, select cdrom for dos and windows 31 because you are making a dos startup disc)
http://www-1.ibm.com/servlet/support/manager?rs=0&rt=0&org=psg&doc=RMIE-38CEKN
Above should be the page for the CDrom driver stuff.
Down the page, download the file marked "cdtpqdos.exe"
cdtpgdos.exe 99,846 English - version 3.12 - CD-ROM Driver for DOS & Windows 3.1 [DSKEXE]
Then go further down and "click here" for further instructions on downloading and creating the disc.
That should take you to this page::
http://www.pc.ibm.com/qtechinfo/DSHY-3TEPF6.html
Actually that page may be confusing.
Dowload the file:: "cdtpgdos.txt " 4,948 README for English - version 3.12 - CD-ROM Driver for DOS & Windows 3.1
After you have downloaded the file, Go to wherever you downloaded it to, and click on it to run. You will get several screens, " If you agree to the license bla bla hit ENTER" etc, and finally you should see, "insert a blank discette" etc.
When you successfully do this, you will have created a INSTALL disc for the CD. You should be able to now use this disc to INSTALL the cd drivers onto either a bootable hd or a floppy drive.
Installation Guide

Now, it appears to me that this disc is the same for my 380xd. That means, that possibly, if there is no downloadable bootable disc for your 760, you MIGHT ALSO TRY looking in the 380xd related stuff for a downloadable startup disc.
Also at the bottom of the "file matrix page" http://www-1.ibm.com/servlet/support/manager?rs=0&rt=0&org=psg&doc=DSHY-3SBNHE
There is a downloadable "Windows 95 Recovery CD Reload Diskette 12 May 1998
v2.50 "
This disc may help you out in building up a usable startup disc, if you can't get things to work another way. If you ABSOLUTELY can't figure this out, repost next week and I'll send you a bootable disc for my 380, however, it's about 50 miles away, and I don't get there every day.
