  18 Minutes of delay so far, hopefully I won't get Deutsche Bahned too badly

  I got Deutsche Bahned a bit on my way back from EF

  Looks like you can't take your eyes off of these things for even a second without them going for your PC

  Mainly shouting into the void, but does anyone happen to be a bit more familiar with the LPC bus (or know someone who is)? I'm trying to implement it on an rp2040, and writes seem to be working fine, but the SuperIO chip (NC6795) doesn't drive the bus after the turnaround cycles. Writes are still received correctly by the SuperIO, as I can see data being output if I write to port 80, and I can control GPIOs fine too. When checking the bus with an oscilloscope, the rp2040 seems t...

  I think I might actually be running into some of the broken aspects of this motherboard now. When trying to get VCore up, I notices SLEEP_S3 was missing on one transistor, keeping a few rails from turning on (in other places, it was present, and according to the schematic and board view I have, they should be directly connected). Since the enable signal for the VRM controller (RT8894A) is still low with no obvious reason, I tried simply pulling it high (first with a resistor), which had the chip...

  The codec on the other board seems to still be dead, but I now have input working on this one (same interface in the end, it's all HD-Audio). It's not a very useful USB soundcard at mono 48kHz, but it sounds not too bad.

  Got another (broken again) am4 board off of ebay, and this time, the VRM controller let out the magic smoke when I turned it on. Hopefully at least the interesting parts are still fine

  The pi5 firmware really doesn't like if you mess with the connection to the RP1 in any way, disconnecting just one lane seems to already make it fail. I don't know if maybe putting a PCIe switch in between could work (but it seems a bit unlikely), but I don't really have the soldering equipment to try that right now (without the risk of just fully breaking this thing being too high, which I'd rather not do)

  I got the firmware for the xhci controller in the b350 loaded correctly now (huge thanks to himko9)! Turns out, python is maybe not a great choice for mmio. Oh well, the board has a few extra wires on it now (from debugging attempts).

  Does anyone have an ethernet card with an intel i210 or i211 controller on hand that they could read something from (specifically the iNVM)? This requires root access on linux. I want to compare if maybe the iNVM configuration is keeping this chip from starting up properly, and since it's OTP, I only have a limited amount of tries to change things. There's probably something in the UEFI that handles whatever additional setup is needed, but I haven't found that part yet u...

  apparently even PCIe gen2 works with my loose wire setup, with still no errors reported (and the speed did double from gen1). gen3 gets no link though, which isn't really a surprise.

  The steam arm64 beta looks pretty neat so far, much lower ram usage then the last time I got it running on box64 (which was a good bit ago to be fair). And I ran into opcodes again which I haven't handled yet in the alignment trap with DOOM 2016, fun

  Got a CM5 now, hopefully I won't break it immediately :3 (looks like the firmware probably wouldn't like what I originally wanted to do, but there's still a couple options I want to try)

  Finally tried to hook up an AM4 chipset to a raspberry pi (someone suggested this on the pi-pci repository a few years ago), and it turns out it mostly just works.
