Hi, I thought there must be someone here who has the card working on Windows 98 SE.

My problem is as follows: the card installs fine under Windows 98 SE (W98 Quickinstall, current version), but then I'm prompted to reboot, and after rebooting, the second I'd see my Windows desktop, the display says signal out of bounds, and I have to hard power off the system.
If the card is removed OR if the driver is uninstalled in Safe Mode, everything works again.
Also I discovered that if you do not reboot the system, the card actually works until then. Which was okay for what I wanted to do (make recordings of the card's FM synthesizer and wavetable), but the card is not working in full duplex mode per default, meaning I can only record one of two channels! Two switch it into full duplex mode, you have to change the configuration of it in the device manager, which is then only applied upon reboot, but as I already said every reboot breaks the system.

I tried this in three different systems and with a Windows 98 SE Quickinstall version but also the official US installation, so I'm pretty sure that the problem is the actual driver I am using.
I don't remember where I got it from, but not the official Terratec website, which only offers a Terratec Maestro 16/96 driver, not a 16/95.

Has anyone got a driver that is confirmed to actually work?

1Maestro 16 (1st edition)  ASC-9308 + DSP-9309A + AD1845, OPL3, M-CD, WBH, 1MB Dream Wavetable daughterboard.
2Maestro 16 (2nd edition)  ASC-9308 + DSP-9309A + CS4248, OPL3, M-CD, WBH, 1MB Dream Wavetable daughterboard, Volume wheel.
3Maestro 32 (1st edition)  ASC-9308 + DSP-9309A + AD1845, OPL3, M-CD, WBH, 4MB Dream Wavetable daughterboard.
4Maestro 32 (2nd edition)  ASC-9308 + DSP-9309A + CS4248, OPL3, M-CD, WBH, 4MB Dream Wavetable daughterboard SAM9203/SAM8905, Volume wheel.
5Maestro 16 IDE (rare)     OPTi 82C929 + CS4231?, OPL3, WBH, IDE, 1MB Dream Wavetable daughterboard?
6Maestro 16/96             OPTi 82C924 + CS4231, WBH, 1MB Dream SAM9233/SAM8905 Wavetable, FM through SAM8905.
7Maestro 32/96             CS4232, IDE, WBH, IDE,     4MB Dream SAM9233/SAM8905 Wavetable, FM through SAM8905.

Can you confirm your card is based on this controller chip: Compumedia ASC-9308
If so, here are the drivers:

Mh nope, it's a completely different model.

I made a picture.

That failure could definitely be caused a driver crash on boot, I was just recently seeing this with my HD Audio drivers in development which were writing to a paged-out address and thus hanging forever or crashing with page fault.

Do you have a serial port on the target system and a null-modem cable? If so, it is possible to load up a kernel debugger and get some idea what is going wrong. https://bikodbg.com/blog/2021/08/win98-ddk/

I have serial ports, but no null-modem cable.

I'll keep your advice in mind since it sounds good, but before spending money on a cable for debugging, I'd ideally like to simply try a driver that somebody can confirm is working on W98SE.

It matches the listed description for Maestro 16/96, but I see "Maestro 16/95" in your photo.
Controller: OPTi 82C924
I don't have drivers at hand for this one.
A generic OPTi 82C924 driver may work, but will probably not enable the Dream wavetable.
