Why do the chmod shenanigans and not just add your user to the “dialout” group? The device nodes are already group-read-writable by default. Docs: https://wiki.debian.org/SystemGroups

Very surprising box art. Was that creepy deep sea fish supposed to convince me to buy this sound card ? Even more curious, at the back of the box in the lower left corner it says "Did you know? - The latin name for the fish on the front is ANOPLOGASTER CORNUTA", so it seems like TerraTec's …
Re: Any 320x200/640x400 games that are not supposed to be displayed at 4:3?
Posted on 2023-10-17, 06:50
Dzzee ( Vogons thread , released 2021) has a "widescreen" mode for its 320x200 output resolution, the hotkey is "W" (and "H" to switch back to 4:3 mode, with 4:3 being the default at startup). The resolution is always the same, it's just the projection that's changed for 16:10 aspect ratio, and it …

New in-box ESS Solo-1 (TerraTec 128i PCI) obtained for really cheap a few weeks ago. Unfortunately, despite all the good things said about its DOS compatibility (and ESFM working fine), I couldn't get its PCM output working reliably on the machine I bought it for, and ended up implementing SBEMU …
Re: How do I set up a CD-ROM in MSDOS 6.22 as Drive E ??
Posted on 2023-10-14, 04:51
As I have learned recently, the name you specify in “/D:” might not be accessible for normal files (in this case, a file named “CD-ROM” cannot be opened while the driver is loaded) so a name like MSCD0001 or something might be better there to reduce the chance of name clashes. Related article: …
Re: Motherboard and PSU for 24/7 run?
Posted on 2023-10-09, 15:09
Depending on what you want to do (and if you don’t specifically need PC-compatible hardware), ARM-based SBCs like the Raspberry Pi 3 or newer might be a great alternative to look into for noiseless low-power 24/7 computing/server use without any moving parts. Also takes up minimal space.

I’ll PM you - let’s figure that out and then publish the results instead of me spamming this thread by uploading a bunch of random builds 😀

Thanks for testing. Please bear with me while we're trial'n'erroring our way to the perfect set of registers... Please test the next build and see if this restores audio again, based on https://github.com/thp/sbemu/commit/af2f663b1 … 249ee108bfea43f

Another build with even less registers, please test if this still outputs audio: https://github.com/thp/sbemu/commit/5071dfe48 … 6e54ec0ac8e14d9 If this still works, that boils down to three registers.

New build from this commit: https://github.com/thp/sbemu/commit/37f9be97ce38dfb9d1e10ee1cc7a96d5986b263d I trimmed it down to a few registers that I think matter, and left out the ones that probably don't affect operation. Please let me know if this build still works on your machine (if yes, we can …

Re: Using a USB keyboard with a PS/2 or AT port

Did a ps2x2pico build this week and it works great. I cheaped out on the case, and re-used a MicroUSB OTG cable I already had. That plastic case is one I had sitting around, but I could replace that in the future with something smaller and more elegant- I wanted to put it into a case ASAP to reduce …

Here's a build that takes your register dump from Win98 and forces all registers to the dump you provided. It also disables mixer writes from sbemu, so mixer settings won't work from SBEMU (and be fixed to whatever you set in Win98). This doesn't check read-only/read-write registers and just …

None of these tests made any sound work on that FSC-E600 AD1980 i865G. Sorry guys :( Looking at the logs, register 0x76 is now properly set. We should probably just try to set all the other registers based on your Win98 dump, and if that works, we just need to trim down to the offending register ( …

I just noticed in snd_intel_prepare_playback() the codec is reset, and then we don't set the register values again, which would probably neuter any register settings done before. So the following patch against the linux-cross branch (clone the source repo, apply the patch below, then build) might …
Re: SBEMU: Sound Blaster emulation on AC97

The ac97dump utility would only need to do a 16-bit read at every 2 bytes, I was confused for a second :) tl;dr: HPSEL and LOSEL in register 0x76 are not set for some reason, so next step would be to figure out why the SBEMU code cannot write to these registers. As long as we don't see those two …

As an update to the SIS7012 support, the ECS K7S5A board I have here apparently also has an onboard SIS7012 audio chip (the initial development happened on/for a Futro S400). Quickly booted up the sbemu build with sis7012 support and it seems to work (e.g. Duke3D with OPL + PCM works). Looking up …
