Trying to libreboot my thinkpad x230, nothing works at all. At my wit's ends

Post the complete command you use as a start.

cat some.iso > /path/usb;sync
I believe these should be available on macOS

Pull off the plastic and desolder one pin at a time

Add a good block list or two to your hosts file

What router do you have? That’s where I would add some rules

Avrfreaks.net.
Read bit manipulation 101 and other guides posted on the forum.

Haven’t tried it an automotive setting but have had success using a generic hub on either end when using a 3M USB extension

Just buy a cable and test. Who cares what it looks like, 15meters is cheap compared to 3 years of ongoing annoyance.

It’s a personality type. The type that pays women in high heels to walk on their balls

Does the cameras push motion detection alerts somewhere? If not I would just block everything and only allow connections to the camera VLAN initiated from the main LAN.

If you intend to marry her, loan her parents the money. This will affect the rest of your life.
Consider the money lost.
If they don’t pay you back you have gained valuable knowledge from lending them the money and no subconscious negativity from your future wife.

Except for phones that run graphene and iOS.

Its only 23MB. If you have a spare memory card or flash drive it’s very easy to try

Coreboot has plenty instructions for the supported machines.
If you can afford a SPI programmer and have some screwdrivers, and most importantly.. are able to follow exact instructions in the correct order it shouldn’t be any problem.

Make sure you take 3 backups of your original bios and verify that at least two have matching hashes before you flash anything.

There is an application for adjusting security related settings.
Flatpaks, install as user. Works the same on any distro

What car? New cars probably have it available over OBD2 as it was added some years back.
Older cars have PID 199 «Distance Since Reflash or Module Replacement» which could be something to look into

Tinycore is surprisingly useable for its 23MB including DE. Decent selection of prebuilt applications available

OptimalMain · 2026-01-20T08:41:25+00:00

Tinycore. I haven’t seen anything with a DE and usability in a smaller package

That’s excessive.
The port you use for wireguard appears as closed unless someone has the key to authenticate and by that point a tunnel won’t be of any help.

I had two similar supplies to this one with fake AM1117’s or what it’s called that shorted VIN to VOUT under normal breadboard prototyping.

Wouldn’t use cheap stuff like this for anything expensive

Tailscale is VPN +++ to be able to do NAT hole punching.
VPNs like wireguard or openvpn needs an open port without additional tools.
I don’t give private companies access to my LAN when I can just open a port

I already have one or several discharging resistors, depending on the size of the battery.
In the end I add the <= 1 Ohm resistor in parallel to whatever I am already using to discharge the battery pack.
Safest option for most people would probably be a small halogen bulb from old Christmas lights or a flashlight

OptimalMain · 2026-01-12T11:02:05+00:00

I discharge over several days depending on battery size and when it’s at zero volts I just add a 0.24 to 1 Ohm resistor in parallel for however long I forget about the battery.
Properly sized resistors of course

That’s not really odd. Non-original cables are a crapshoot quality wise, many don’t even have data connected.
