ES1868 AudioDrive ISA in Windows 95

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View

I'm working on an older system, trying to get it up and running.  It's
going well enough, but I need some direction in diagnosing a sound card
problem.  There's every reason to suspect all of the discussed hardware
previously worked together under Windows 95, but I cannot exclude the
possibility that the sound card has simply failed.

Ok, here's the setup, more detail upon request:

Mainboard:  Biostar MB-1433/50UIV-A ver. 5 (Socket 3)
Processor:  Am486 DX2 80MHz    
Memory:     16MB (4 x 4MB modules)
Video:      1MB VGA ISA Card
Floppy:     1.44MB 3 1/2"
Optical:    2x IDE CD-ROM
HardDrive:  540MB Conner CFS540A

All of that stuff seems to be working.  The HDC, FDC, serial and
parallel ports are provided by an ISA I/O card.  The third ISA card is
the sound card.  It also has what appears to be an IDE connector, even
though it is not explicitly marked as such.

FCC ID (E5X1853L) and chip identifier (ESS AudioDrive ES1868F G486)
suggests to me that it's: (I can't find a good picture of it online, but
if somebody wants to see it I can post one.)

Sound:     Ensoniq ES1868 AudioDrive ISA

ESS suggests that it's supported in Windows 95 on this web page:

Those linked files are apparently gone, but I've found (presumably)
those resource by searching out the relatively unique filenames still
embedded in those pages.

The board appears to only have 1 labeled jumper that controls the IRQ
setting: 12 or 15.  I've left it set to 12 and left it (as with the
other two ISA cards) in their original slots.

I can't get anything to see the card, though I am admittedly unschooled
in the pre-Plug 'n Play era.  I've tried these apps to look for the card:

* Microsoft Diagnostic (MSD)
* ESS' DOS Setup Utility for ISA AudioDrive
* Windows 95 Setup
* Windows 95 Add New Hardware

Right now, I suspect that there is a BIOS setting that needs adjusted.
Unfortunately, I don't have much background in that domain, and no
manuals for my motherboard or sound card.  Fortunately the AMIBIOS
(11-10-94) does not have a lot of settings, so I'll post them here, with
the options delimited by a pipe (|).  My comments will be included in <
and >.

Any ideas as to how I should proceed will be appreciated.

Probably either an IDE controller onboard or a midi header,
I can't recall.

It definitely has win95 support, the following is the newest
driver I could find in my archives.  I can only assume win95

can't recall if I've ever used it on win95 or not, but it's
worth  try.  Supposedly win98 and thereafter have a driver
for it included on the OS CD, if all else fails you might
consider win98 or 98lite running win95 shell if it needs to
be low overhead.

It turns out it was a bad ISA slot.  It should have occurred to me
earlier, but I got hung up on my unfamiliarity with ISA cards and
