Ivyrain can not be upgraded to use Heads.
If one does the hardware flash, take the computer apart, put the clip on the chips. Then one can by keyboard upgrade to Heads.
Heads is the part where you would use a Librem Key , or a Nitro Key and verify some of the parts of whether the computer has been tampered with.
One might wander through salvation army stores, good will stores, and find an X-230, which might be damaged. and a useless battery.
While no one else has mentioned this. Might be a good idea not to attempt to hardware flash with fluorescent lights around, they throw electromagnetics
Be nice if someone can talk about how long it takes for the parts of the hardware flash coreboot to run.
Realize all this advice comes from an individual who bricked an X-230. I have a second X-230, which I did not tamper with doing anything. and it died, I think of being overheated. I was not tempted to again put 1vyrain on it, because that might be part of the process of bricking the first one.
If someone in the US did Coreboots for a price, I might be encouraged to somehow get a laptop to send them for, what, $125.00 or so. .
Shipping to and from Europe, with the current Tariff issues.
If I had the money I might buy from Nitro Key.
then again, I really want more RAM than the 16 GB of an X-230.
BTW: No one has mentioned that Intel no longer provides microcode security updates for X-230. and other computers. The same with my T-480 (Intel 8th generation processor) no longer gets Intel Microcode Security Updates.
Edit: If you missed it. What 1vyain allows you to do.
The X-230 has a “white list” – Hardware items that must be present, or the Lenovo X-230 will not boot up. Things like must have a Lenovo Battery. The correct WiFi Chip. The correct IBM keyboard. There are better versions of these items.
1vyrain allows one to use substitute parts. Although someone who has experience says the actual Lenovo batteries are better. There is a faster WiFi chip. A better keyboard.
1vyrain also makes it so the Intel Management Engine does not run.
Downside: I have been told that, even though I replaced the BIOS firmware with original. That I should not have attempted doing the hardware Flash. There are several different BIOS chips which might be inside the X-230. I could not read the number on top of the Chip, and my attempt to restore BIOS after bricking, was not successful.
I see some posts who offer some advice. One fellow says there is one particular BIOS which can be installed on any Lenovo X-230, and it would work. (Back to hardware Flash of Core Boot.) Another said that one of the things which can happen, is that there is a resistor, which can get destroyed -accidentally- putting the clip onto the Chips. One of them that is. There are two to do hardware Flash on.
Thought I would save you some research time.
