Thanks and nice to see someone else also made progress on making theese boards usable. Maybe i will try to dig up one of mine that also have two unresponsive ram slots and flash your BIOS. I don't think the issue with RAM slots could be fixed from the BIOS side. The RAM slot problem was more likely …

Some updates... I did some tests with dISAppointment on Windows XP and to my surprise it worked reasonably well, though can't be sure it's reliable enough. Setting Sound Blaster 16 as preferred audio device and tested playing some games. Everything looked good for quite a while (at least for an hour …

Did you ever get to test the 45.23 driver? Because my hope was that those older drivers somehow enable dual link dvi, which is broken in all the 77.72 and later versions that I can test with my Quadro FX 3450 and 7900gs/gto under 98. Nope... I'm afraid the card was likely dead shortly after that …

On your board irq 3 was probably shared by more devices so as you freed irq 5 it moved one device from irq 3 to 5 to avoid sharing. Maybe it would be possible to disable device taking irq 5 after boot by some control registers? On my motherboard, IRQ3 was taken by line E. USB3 controller which is …

pcicmd 0 1f 0 60 pcicmd 0 1f 0 68 I get 0A04800B and 03058080 respectively, so it looks like IRQ7 is free. I've always needed to use IRQ 7 with the disappointment, but I tried 2,3,5 and none of them worked either. I've disabled quite literally every onboard device in the BIOS, but this board has a …

I'm also curious how this is done. Very generally I think the magic is done by PnP enumarator code during POST. Every device should report a list of resources it can assign and what values are prefered and if it can be shared. Eg. device A says I can do IRQ 5, 6, 7, 8, 9 and 5 is prefered, device B …

Well, NT 3.51 is still doing fine even on newer hardware like Intel 13th Gen CPU and an Asus H610 motherboard. (this board has MPS 1.4 support that works 100% OK with NT4 ) I can confirm that NT 3.51 runs completely fine, 100% stable, with standard kernel. This was a surprise, but runs with …

I've found the answer. Actually port 21h is being used for IRQ stuffs and should not be touched. So I'm having the same problem as you (interrupts not firing), except using your latest code that doesn't touch 21h doesn't seem to help. DMA is working great though. Any ideas? Maybe I can set 21h to …

Sorry for another bump... I just migrated an existing system with NT 3.51 to another board with a X99 chipset and now it can't start, complaining about INACCESSIBLE_BOOT_DEVICE. On the other hand, it seems most Intel chipsets including current ones are MPS-complaint to some extent as the MPS …

I... Can't find a datasheet, but this one page blurb claims a pcie to isa bridge chip exists with full isa support except bus master. Assuming it's accurate, would that imply that lpc isn't needed to support sound cards? https://www.fintek.com.tw/index.php/products/i-o-controller-and-i-f-management …

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? …

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. …

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 …
