That devkit looks pristine. I remember there was an MPEG Layer II (MP2) audio decoder for the ADSP-2115, it's dsp_mp2 for Linux from https://www.mpg123.de/download.shtml. The code is mostly a kernel module that uploads the DSP code, which is only available as a hex dump so hopefully the devkit has a …

AIUI the DOS compatibility depends on the south bridge. Wikipedia says the KM400 and KT400 can be paired with the VT8235, VT8237(+) or VT8237R(+). FWIW I've used an ESS Solo-1 (one of the "new" remanufactured cards from China) with a VT8237R+ paired with a CN700 and VIA C7-D, and it works fine in …

Speech is slower than normal with the Gamewave32 drivers - tried 1.4 and 2.3. Hilariously sounding voices in DUNE2. This is only when using the GENMID.LD from these sets. When using these drivers and the DSP001WA.LD from the Cardinal driver set, the speech is normal. This leads me to believe that …

I wonder how large the performance delta is between the GX2 and GX1, as it seems that the GX1 is only marginally--if at all--faster than the GXm. Per-clock the GX2 is likely going to be marginally faster than the GX1, it's probably only the doubled, and split, L1 cache (I got mixed up, it's the LX …

This article suggests not as the alternate coding was removed in 5.1 (aka XP). It also suggests that Rise CPUs do support CMPXCHG8B even if they do not advertise it in CPUID, which explains why Server 2003 works.

It's interesting that the GX1 is i686 class. Do you think there's any real implications to that? From what I've read, the GX1 is not really a substantial advancement over the GXm and GXLV, but just a refinement and more of the same. It just means it'll be able to run newer OSes, like current …

Short answer, yes. It's in the datasheet, for the GXm it's in section 9.2.1.2 table 9-19 where bit 8 of EDX is 1, indicating CMPXCHG8B is supported. This blog post has the cpuinfo dump from Linux for a GX1 and, under flags, cx8 indicates support for CMPXCHG8B. It also supports CMOV so it's really an …

On Linux, this uses a different driver from the Sony: https://tldp.org/HOWTO/CDROM-HOWTO/x97.html so it's likely you'll need a different driver in DOS as well.

You might wonder if it was marketed with the slogan "I can't believe it's not FM." Lol! Thanks for the recordings, they sound just like the ADSP-16 Wave and SoundWave 32.
