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. Except in …

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 …

Will the Orpheus work in an 8 bit slot? I haven't personally tested it, but this should work fine. The reality is that there is no part of the card that uses 16-bit transfers; the extra "connector" (16-bit ISA) is there only to provide access to DMA 0 and additional IRQ lines (above 7). Using the …

I can't say if/how it will help with this specific design, but it definitely makes a …

it's possible the newer revision does not have the DMA bug, I'm not sure how to check for this though. The discussions I've seen were about the D1011. Anyhow, testing your hypothesis should be fairly simple: get a Linux distribution that will allow you to use the older ITE driver with DMA enabled. …

I haven’t tried that exact DMA thing, but I suspect it to cause instability. With a file system that is already not natively supported by a Win9x driver, you can bet that that won't provide any benefit. Furthermore, if you look at what I mentioned a few pages ago, the RDC controller has a bug that …

Thanks for this answer. Do you remember which timing options have you used for the Socket 7 and 440BX boards? Were the socket 7 boards Intel Triton based, or have they used some 3rd party chipsets?

I had no idea games could alter the card's configuration, that is a weird side-effect! It can be quite an annoyance, and difficult to figure out, especially when you don't expect it. They usually don't also write the new configuration to the EEPROM, so a re-boot is usually enough to get everything …
