I wouldn't be chancing damaging the card itself just hacking up the 
cable a bit and in such a way I could return it to original once 
and if I get a plug and play O.S. 
My concerns regarding modifying the cable is limited to
possibly damaging the SoundBlaster sound card and or the CD-ROM. 
Analog audio is analog audio but who knows whether the two chose
the same color coding is anybodies guess.

 I'm aware Turtle Beach was highly thought of but I've no software for
 it nor in fact have I yet pulled the card to find the model 
 number to get specs off the web. It *is* the sound card that was 
 plugged into the CD-ROM when I salvaged the machine from the trash.
 Now that I've got it all up and running perhaps I should try
 the damaged drive with Win 98 on it again attempting to boot
 with boot disks obtainable from www.bootdisk.com?
I don't think I'll find a wiring schematic for the Turtle 
Beach as these things are sold as plug this there.
 
Might not want to sell the Turtle Beach either because support may 
exist in Linux and Win 95.

 Yeah and I'm looking forwards to that once I get an I/O 
 card that supports ATA 133. Loading my SoundBlaster software
 over itself so it'd recognise the new CD-ROM was very fast
 with this very small buffer 3800 spindle speed Seagate
 thrashing all over the place as the software loaded.
 Don't really see any jumpers on the board so I'm assuming 
 you answer "none" to the 4 IDE device drives in the CMOS
 to disable it?

Don't I know it.

 Yup.

 Oh you can locate Linux above that limit but the 
 boot itself must reside under that limit.
 My understanding it you can make Linux boot from bootblock or
 boot the image from even a 3 meg DOS partition
 under 1,024 but to boot above you need this relatively new
 technique I read about in newsgroups.

Nope, prompts for OEM Vidio driver and there are none for this ATI.
I'm stuck until I either get Win 95, 98 or X-Windows
running :-(

Hmm, something I can try. 
I've got "UMB,high" in my config.sys.
I've also got 90K upper memory free.

Not a clue though it doesn't seem to cause a problem 
crashing out with warm boot, no lost files on running chkdsk/f.
That's another thing I can try modifying the video memory I've
denied video driver unused in the old machine to gain
some to run programs.

 WC> 264VT-A4 here and search does not reveal a Win 3.1 driver.

I'm a member at drivers.com and neither they nor google reveal
a 3.1 driver.

 CA> I'm guessing you have an OEM version of W95? 
 
Good guess, given to me in shrink wrap with registration
number sealed. Originally for a Dell it also suports
2 other machines including NEC of which this is one
but _this_ CD-ROM drive wasn't manufactured until 1999 
and I recall you've only three options for CD-ROM drive types
to install this OEM package.
The Pentium was built in 96 with the 40X drive obviously 
added later.

 Will check for availability and price and yes I've been reading
 about the Windows SE debate.

 Hey check this out, just tried the headphone jack and
 four buttons on the CD drive and it will play audio CD's
 there with volume control but no bells and whistles
 except it does have a skip to next track button.
 Need a pipe cleaner and some solvent though as the contacts appear 
 corroded per having to jiggle the jack a bit to get both channels.
 Pretty good drive and the price was right ;-)
