I’m going through the setup for my awesome new Orpheus II and I wanted to make sure that I was configuring the hardware properly. Default SB16 settings are: SET BLASTER=A220 I5 D1 H5 There is an important distinction to be made here. This is not a Sound Blaster 16, and the Crystal CODEC cannot make …

I suspect that maybe that statement may be related with a post user Itling started here last year: https://www.vogons.org/viewtopic.php?p=1095313#p1095313 reporting some problems with samples, supposedly caused by RAM not being initialized (which in fact UNISOUND does). I stand corrected. It was in …

To initialize GUS part, just run IWINIT.EXE -V9 to see everything. I think it is worth mentioning that the "v" in IWINIT -vx (where x is the level of verbosity of the output) must be lowercase. This seems to be a bug in some (most? all?) versions of IWINIT. As has been pointed out, for DOS, …

I don't know if you're aware of them, but there are some titles that don't work well (or at all) beyond a certain amount of local GUS DRAM. Do you have any facility to tell your firmware to limit available DRAM? I would assume that, if you were interested in such a feature, it could be configured …

Should be similar to the ARGUS card (check that thread ), that accepts pretty much any FPM or EDO RAM that is 5V and should be 70ns or faster. I'm using some cheap single rank 16MB FPM that I bought on ebay. I also tried dual-rank 32MB EDO and it works fine (but only uses 16MB). That's exactly …

GUS drivers do have an option to test DRAM - it's not super accurate but it will reveal severe issues thing is if a ram stick fails the test you just replace it and go on with your life , easy and cheap The part about it not being particularly accurate can't be emphasised enough. Basically, if it …

It sounds like the ALi board is a recent acquisition, so maybe you haven't tested extensively yet. I'd be very interested to hear of any oddities you find when you get to more in-depth DMA or timing tests. Granted this isn't a P5A of any description, but it sounds like something is already different …

I am setting up a new testbench for PicoGUS because I grew tired of the flakiness of my original system (a motherboard salvaged from an old Compaq desktop with corrosion issues) - it's a motherboard based on a somewhat later Super Socket 7 platform, the ALi Aladdin V. I wonder if there isn't …

if you are booting into 98SE you don't need any DOS drivers loading for Orpheus , remove that line that calls orphinit as it could interfere with the windows driver I have to agree with this; ORPHINIT is an integrated configuration/mixer set-up tool specifically intended to be DOS-only.

I have some ideas for how to handle multiple card enumeration, inspired by the ISA PnP spec's card isolation protocol which is pretty clever. Each card should have a unique serial number in its flash ROM that will make that possible. Having looked at it in some detail, I agree that the ISA PnP …

This is certainly an interesting project. I might just want to build one of these when the budget is a little less constrained. Since that's not feasible yet, I'm wondering if any of you have done any testing to compare the output of this design to a classic old GUS. It could be interesting to see, …

@640K!enough , do you think it might be useful and hopefully not too much work to make a small text UI/CLI utility to allow setting some of the more common/interesting CS4237 registers to given values ?

640K!enough is there way to toggle SRS mute switch in DOS? When I'm unmuting SRS channel in Windows mixer I'm getting exactly the same noise on SPDIF as in DOS "analogue" mode. ORPHINIT allows control of all SRS features via the standard INI file (in the mixer section). It is off by default, but …
