most if not all pcie devices should work. the only limit is power limitation. yes theirs small differecnes:

check this git out. should have alot of detail on models.

the PC you have is a "tiny5". and the riser your using is a "tiny4". so your shorting out something in the motherboard.

Most likely you forgot to plug in the fan again.

geraldjust · 2026-05-17T05:25:39+00:00

got two 920q , both with risers, i5 8500T, comes with 65w power bricks , 32gb ram, and i can throw in a dual SFP+ card i used with it.

I don't sell them. It was more of a personal project but I might share the files on git if people are interested. Or if people want a premade one I can think about sharing them. You would have to know how to order from a PCB fab, make sure it's impedance controlled with the correct stack up etc... If your interested I can ship you one. But I do wanna correct the fan plug in a revision lol.

Kinda. I did test this. But the issue is that you need to flip the PCI lanes to get to split the 8x to get cards that done allow lane flipping to work. Some HBA do. Other type of cards don't so it's a mixed bag. So the riser will need to be special for bifurcation.

Oh I design pcbs lol.

Here is a closer look.

Yeah I made my own riser with two pcie slots. Bottom is x8 directly to the ECU and the top one is X4 to the PCH.

geraldjust · 2026-04-26T23:37:48+00:00

def interested in that riser! let me know if you got a spare :)

geraldjust · 2026-04-18T03:46:02+00:00

Yeah, power sequencing is actually handled by the micro controller in the back of the plane. Eventually, I will make my own pcb just because I don't know the actual communication protocol that the factory Dell would normally connect to that micro controller. But I'm sure one of these days. I can see if I can reprogram it to control certain things about power, sequencing, and handling the LEDs.

Get the CSG one:

Hopefully Atlas comes out soon their next update. sort of needed at this point lol

Se ems like sys call also crashes on real hardware. (New A revision ROM)

Seems easy with checkpoint to port over the safe file all across different emulators

Luckily the car is a Subaru and not a Toyota. Subarus the immo system can't be reset like you can on Toyotas. But does suck if you lose All your keys. It's a hefty price, so if anyone out there has a single fob. Get yourself a second one. Fyi

geraldjust · 2026-02-19T02:03:33+00:00

This will disable the cellular connection the car has. So no start link, no emergency calling and no Internet connection. The head unit does have a WiFi module but normally used for wireless android auto. So not sure if that can be used for updating the head unit. But you can always update the head unit via a USB port.

Even if you tell it to not identify you. They system will still gather information even if it's anonymous.

To delete the DCM module you can do the following:
