The switch turns 16x 2.0 lanes from 990FX into 32x 3.0 lanes for the slots, as weird as it sounds. There is no 16x+16x uplink, the switch does support it but AFAIK you can't bond them together to speed up a single card (the 2019 Mac Pro has this but only lets you select one uplink for each slot).

Interesting yet deceptive. They put a PCIe 3.0 switch on a single 2.0 x16 uplink (the manual proves the article wrong) and called it a 3.0 board. It's useful for corner cases at best, like running 3.0 x4 SSDs from years later.

The STPC Client was only specified in 66x1 and 75x1 bins, there is a later Consumer II at 66x2 with the same package and feature set but it might not be pin compatible.

These chips are fascinating, there's a final 686-class (Rise mP6 based) one that apparently never shipped in volume.

The underlying plastic plays a role. On this laptop, isopropyl just stripped the coating to reveal translucent plastic underneath, but degreaser cleaned the coating without stripping it: bsky.app/profile/mess...
In trying to clean the sticky rubberized finish on this old laptop, I ended up stripping a chunk of the coating, then asked myself: why not go the rest of the way? It looks way cooler than I expected. Happy little accident.

The active USB extension cable has failed. Hub no longer enumerates. I (literally) cracked it open and found the chip is heating up quite a bit on one end. Very minimal design, too bad the chip markings were sanded off.
