Re: dISAppointment - LPC to ISA adapter - ISA on modern motherboards

I captured the LDRQ# signal during SBDIAG sine/tada test on my P67 MB with ESS ISA sndcard. Under Doom it looks similar. During boot and when soundcard is not used it's still high... Btw in my case the sbdiag sine noDMA is silent, both on real ISA and with SBEMU, only DMA sine plays. How about you? …

I've been curious about this behavior for a long time... what exactly could be causing it and …

wow now thats a find. a full sb working on new motherboards that still suport bios emulation (csm) if this can have drivers for win9x would be very nice. trust me i had win98se on my z97m-d3h but with pci soundcard. 3d accelerated games and a3d sound was as good as on my p3 rig. aureal vortex 2 has …

Apparently when testing Duke Nukem 3D, it feels like the wires I used to connect the TPM port to the dISAppointment at the moment were a bit loose. After the music froze halfway, I could not detect the Fintek bridge anymore when I exited the game and ran my test program, even after reboot. …

That's great news. Do any games work? I did some tests with a few actual games. Skyroads: Works okay. Jazz Jackrabbit: Works okay. Spear Resurrection (Wolf3D TC): SFX only works occasionally. Duke Nukem 3D: Works okay, but after a few minutes sound stops and music freezes. Apparently when testing …

If you run SBDIAG without clearing the DMA registers does IRQ work? If it does, maybe go through the DMA registers and see if leaving one alone fixes IRQ I've found the answer. Actually port 21h is being used for IRQ stuffs and should not be touched. With that port excluded when resetting DMA …

BTW you tried SBDIAG? It has source available so you could maybe put debug printfs in it to get more info about how much DMA is working Thanks for pointing out about SBDIAG. Just tried it. Looks like DMA is indeed working, but IRQ is not. I'm hearing only a short tone when testing DMA, and no …

An update on my tests... I think I'm getting even more closer. Turned out I indeed need to reset all DMA registers on my test system after configuring the host LPC bridge. Back then I omitted that part as it was never required for RUBY-9719VG2AR. Guess the boot-up states of the DMA registers are hit …

did you document somewhere location on PCB of GPIO you used on your Asus board? For all those Intel chipsets, LDRQ1# is multiplexed to GPIO23. How to configure that pin's functionality is already documented in their datasheets. The location of LDRQ1# varies depending on board design. You need to …

yea, very bare-bones sb pro 2 with opl3 emulation. only issue was GPIO setting, once I figured it out it just worked. What's TPU btw? Something exclusive to ASUS, on very high end boards. It's responsible for some optional performance tuning (controllable by switches in some cases), as well as …

probably a bit off-topic, but maybe you'll find this interesting :) https://github.com/nukeykt/LPC-Sound-Blaster instead of building LPC-ISA adapter, I tried to directly implement sound blaster compatible 'dsp' over lpc bus using verilog. I used z97 based asus rog maximus vii ranger, LDRQ1 was …

Tried inspecting the LDRQ#1 line with a logic analyzer, but I wasn't able to capture anything promising... all I got was some messy captures of alternating highs and lows (appear as thick bars unless zoomed high enough). Perhaps breadboard isn't a good idea and I'd better off use a splitter cable to …

I don't have much experiences with modding modern AMI BIOS. My Gigabyte use old-style Award BIOS so the key tool I use is CBROM to add/remove/extract various modules. There was also MODBIN tool for modding SETUP entries but it's too old for newer Award BIOSes. I remeber I also had some "hot" …

AFAK modern boards cannot run without ME and if it was fully removed or corrupted this cause system shutdown. This is why someone created MEdisabler that remove/disable almost ME features but leave some criticals.that prevent the shutdown. But in normal case the BIOS modding tools.shouldn't touch …

Yes that checks out in Intel Application Accelerator, its seeing it as 40 not 80: https://i.imgur.com/9c9ffFs.png https://i.imgur.com/lUuR2Ph.png https://i.imgur.com/wvtckEf.png And you can see here compared with the 60GB HDD (only in the bios because I wiped the drive): https://i.imgur.com/0Xdwncg …

I see the image... But the fact that it offers ... very very old... single-word and multi-word DMA modes, and tops out at UDMA2, makes me think the system's bios just cannot handle it... But OP says it correctly shows UDMA5 for a spinny disk. Curious. I'd guess you are right that this is an 80-wire …

I hope this isn't some annoying bug in the bios but at this point it looks like it probably is. Also the adapter is connected directly to the IDE header/port on the MB, so its not the 40 vs 80 wire thing. The same adapter works at "full speed" on a Thinkpad T42. The 40 vs 80 wire detection problem …

Apparently different ME versions require different FPTW64.exe Also, when I did mine I used the -BIOS option which I believe only replaces the 8mb of the BIOS code and not the ME/Boot/whatever. What board is it? The Ruby? ASRock X99M Killer/3.1 So far I've only found this BIOS mod for this board. …

Really? I just modded my Asrock z390 the other day with no major issues outside finding the correct flash tool to work with the ME. So... do I need to somehow deal with ME when modding BIOS? I wonder if the board shutting itself down after stucking at 94h for a few seconds has something to do with …
