There is already an Orpheus available and AWE64 Legacy on its way (?), so I don't think there will be enough interest. There is no currently-available card that offers all of those features, though, and certainly not one built exclusively from new, readily-available parts. Orpheus offers better …

I still plan on throwing the orpheus into one of my other socket7 systems but really wish I could have used it in the dell as it has become my primary DOS machine. I think I can pre-announce that the upcoming version of ORPHINIT will include support for another initialisation method, which should …

I may be remembering incorrectly, but I was under the impression that Doom used an integrated version of UltraMID. In most versions, this reserves 8 voices for digital audio/effects, and uses the remaining 24 for MIDI-based music. I don't remember if that could be changed. Other than the instrument …

That helped a little. I assume it also means that just the wavetable (and not FM) cannot be muted completely? Otherwise it would have been possible to use the 3,5mm output from X2 and connect it to CD-in. There could be a way to support that, but I haven't yet found an elegant way to do it yet. I …

I went on and calculated my total costs in the past months for the project. I set out to build 2 units (highlighted below in the chart) to save on costs. Keep in mind these purchases: It is an interesting project, but is it correct to say that it cost upwards of $600 (CAD) to build the first unit? …

After I rewrote it with this thread's good CS4237.BIN, all works, without invoking the /o (override) switch of cwdinit.exe. Are you sure you used the right file? Unless I'm mistaken, the BIN files I uploaded were only for hostload init; they lack the necessary header for EEPROM use. You may want to …

Hostload works perfectly on my Vortex86 SX motherboard and PC/104 CS4237 soundcard. As there's basically no difference between the PC104 board and my carrier board for the Vortex86 DX SoM, I'm beginning to wonder if there's something weird about the DX variant when it comes to ISA. At least it …

we'll have to wait for 640k!enough to tell us if a "flip stereo" option can be implemented but generally speaking CS4237 does not suffer from flipped stereo channels to my knowledge... Nothing I've seen so far suggests that this is possible. I suspect it was a design choice (worked correctly on …

It seems that, at least on my configuration, hostload will only work if there is already a somewhat valid EEPROM attached. Is that expected behavior? If not, is there anything hardware-wise that could cause hostload not to work but EEPROM to be fine? I have attached the draft schematic just in case …

I'm sorry, I think I might have wasted your time - just for kicks I tried re-writing your CS4237.BIN file (with the first four bytes added) using my TL866 and it worked this time for some reason. I guess I must have messed up the first time. At least that does confirm that the files I have been …

A revised version of rasteri's bin file is attached. I removed the EEPROM header (first four bytes) and stripped the part that is supposed to be firmware patch data. The rest is entirely his file, byte-for-byte. To use this, simply add it to your hostload directory, and invoke it with " HOSTLOAD …

Part of the problem is that, per Crystal's own tools, that original file is not quite valid. The hardware configuration part seems acceptable, and the PnP part should work, but the size is definitely incorrect. It is unclear how the part will react to that, as actual behaviour varies significantly …

Since it can affect the CS4237 in quite a number of ways, I would first tend to the EEPROM issues, and worry about the rest afterwards. For starters, try 3.3 kΩ for R9, with R10 unpopulated. If you're still not getting anywhere, try re-flowing the related pins on the CS4237. Frankly, the bulk of …

I have been looking at a few different parts lately, so am sometimes confused. It looks like this EEPROM only needs a resistor for SDA (Crystal calls for 3.3kΩ for R9). EDIT: So, to clarify, R10 should not require a pull-up, and I'm not sure the CS4237 would like that too much. Certainly, don't …

I don't know if this is a dumb suggestion but why not use the FLASH package from Orpheus website? That depends whether the chip will have (or allow) the control port to be configured directly, without first having the correct hardware configuration data. It might work, since it has a valid PnP ID, …

These should do the trick. With the updated files, replace those in the HOSTLOAD package, and try again.
