Gravis ultrasound clone - how to dump ROM? STB SoundRage 32 Pro

I've got the STB SoundRage 32 Pro "USA201 rev A". It has 512KB RAM (SOJ, no SIMM slots) and no TEA6330T chip. I found a bit of info at "STB SoundRage 32 / 32 3D" at https://www.dosdays.co.uk/topics/Manufacturer … stb_systems.php (typo in FCC-id, site owner notified). It works with the 2.34 Interwave …

Ultrasound support - I've got a "STB Ultrasound" board. Could the PNP ids be added for that one as well? :) It uses the InterWave AM78C201KC chip. The id is "ADV550a". For more IDs, see https://elixir.bootlin.com/linux/v5.17.4/source/sound/isa/gus/interwave.c#L121 I didn't manage myself to patch the …

I gave the bios chip a third run in the TL866II programmer. By disabling BOTH pin detect and check id in the Xgpro software, I was able to read the chip (id reads as 0xC211, but should probably have been 0xC21A according to datasheet). I don't trust this chip, and I'm happy about replacing it. …

Thanks! I tried it, but the resulting seg-e.bin unfortunately has empty (nothing but FFH) contents. I made sure to delete the old .bin files first. DSC_1262.JPG I tried the variations CTCHIP34 UMC498GP /35:=%000000 CTCHIP34 UMC498GP /35:=%00000000 CTCHIP34 UMC498GP /35:=%00000000xx with no …

Yes, I'd be happy to help. I've got access to this motherboard. There is something to work out - romsavat.exe produces a 64KB dump, same as on UR. Another dump bios tool, dumpat, produces an 1MB file. Perhaps you're able to cut that file and extract the 128KB rom? See attachment. The first 64KB of …

In my case, I used two Siemens HYB51417bj-70, taking care to match the speed of the other ram chips on board, or lower. Mine has 70ns chips. There are multiple chips that will work, they must match the specification, e.g. 256k×16 DRAM FPM 60ns. The socket is SOJ-40. Take care that there are both EDO …

The on-board video of M571 worked on my board. It is, as mentioned, slow in games. The Windows 9x-drivers are decent. The bios makes you configure the refresh rate of the screen. I added it to Vogonsdrivers, at http://www.vogonsdrivers.com/getfile.php?fileid=1875

Similar to how there is a bracket for SFX to ATX mounting. If you can find a suitable PSU (power wise) for what your're trying to accomplish in an SFX form factor then that will probably solve your problem. Yes, it would! The screw holes on the SFX is in a perfect square, allowing me to turn it …

Similar to how there is a bracket for SFX to ATX mounting. What exactly would the bracket do? It would have two sets of screws, one matching the screw holes on the case, the other the psu. I imagine the bracket is mounted on the outside of the case, allowing room for two sets of screws. …

I want to use an ATX PSU in an AT tower, as I have no reliable AT PSU. The mounting and screw holes gives me trouble. Because of the fan's position on my ATX PSU, I have to turn it upside down. Then, none of the four screw holes match between the PSU and the case. Is there a bracket or adapter I can …

I installed Windows 98 SE with USP3. Works ok! Somewhat slow, but not horribly slow. Enabling DMA-transfers for IDE made a large differences. Using an additional IDE-44 Compact-Flash adapter, I ran a cable to to the opening at the back. This makes it possible to easily eject the CF-card for copy …

I'll make an update on it when it arrives. I ordered it from Japan just as an interesting piece of hardware. Apparently a company called IO-Data also made similar adapters although I haven't seen any for sale. Did it arrive? I just got my Melco Buffalo HK6-MD366-N2 adapter. Also looking for …

The missing parts were soldered back and viola! The card is working. Some years ago, but I wonder how did you attach the MIDI port? By running a cable to the other board in the pictures, or on the same board? What were the missing parts? I see an added 7805 VRM, a power plug, two pin headers, and a …
