Hello, new user here. Felt that this place would be most appropriate to discuss this issue. I don’t know if anyone here can really help me with this - at the very least, I just want to yell at the sky and see if it says something back.
The Intel BE200 - Intel’s latest PCIe Wifi 7 module. At this point, it’s over a year old, but it still seems to be terribly supported. When I learned about it months - maybe half a year ago, interested in upgrading my Ryzen 5 5500U lapop’s AX210 with the latest module from Intel, I read stories of people having issues with the card causing their systems to not POST. The predominant forum thread regarding this issue seems to be the following Framework Community Page thread titled “Intel Wi-Fi 7 BE200 and BE202 compatible with Framework 16?” (Can’t post links yet 
)
Supposedly, the BE200 seems only fully-compatible with latest Intel generations of CPUs. Meanwhile, it’s hit-and-miss on every other platform, and definitely isn’t as consistent on AMD platforms. Ironically, Jeff Geerling got it to work on a RPi5, making a video about his experience and posting on that above-linked thread as well. Even more strangely, a user on the LTT Forums mentioned he got it to work on an older Skylake system (last comment on thread titled “Intel BE200 caused X570 motherboard fail to boot into Windows 11 or Windows recover/installation enviroment”).
For my attempt, I got one and installed it into my Ryzen 5 5500U laptop running Linux Mint 22.1 and Ubuntu kernel 6.13.5, and it couldn’t boot into the OS proper. I could get into the GRUB boot menu and attempt to boot in recovery mode, but this is about as far as I get before the system reboots itself (Imgur image: WN99WGZ). Complains about being unable to allocate resources to any of the “EISA” buses - not exactly sure what those are. Internal chipset or I/O buses? In any case, I think I’ll have to make a return. 
I’m suspecting the same thing as those on the Framework Community Page are - there must be some sort of incompatibility between most BIOses and the firmware for this Wifi module.
Can this be fixed by Intel with a firmware update, do motherboard vendors have to support this on their end with BIOS updates, or can there be some way to rectify this issue via OS patches/fixes? Is Intel screwing customers by dramatically narrowing the scope of platform support in the interest of saving a buck and/or pushing people into buying their newer platforms for guaranteed support? Is it perhaps, given that Intel is being stretched quite thin these days, this product hasn’t gotten the internal support needed to make it as compatible as prior products were? Or, does Wifi 7 entail new requirements for operation that make is somehow incompatible on various platforms?
These are some questions I have. If anyone here have any answers to those questions, or want to share their experiences with their BE200s, please do!
