Intel AX211 no-vPro to AX211 vPro upgrade

safari · August 3, 2023, 12:19pm

Hello, sorry for the silly question, but I am quite new to CSME.

I have new HP Elite 800 g9 with Alder Lake (CSME 16.1.25.1991), it comes with all the vPro ingredients (AMT is available and enabled, KVM works) but the Wifi RF module, which is a non-vPro part. Since I might actually need it for a while, I wanted to check whether I could simply swap it with the vPro version and see it show up under AMT.

So, I dumped the SPI with FPT and loaded it in FIT and could see that under the “Wireless LAN Configuration” section ME CLINK Signal is enabled (so the vPro communication bus is enabled) and power well set to SLP_WLAN, so here everything seems to be correctly set.
However, I wonder whether this would be sufficient, or if there is anything else that might not work, for example the ME binary might not have support.

Any thought?

By the way, I can share the SPI image if it helps.

Thanks!

Please post the complete output of MEInfo -verbose.

What cpu and what LAN card is installed? Chipset is Q670?

It’s not very common that vpro- enabled machines don’t have vpro enabled WLAN Cards?

I tried but I got a “PCH is not supported”, I guess because it’s version 16.1.25.1932 (vs. version 16.1.25.1991). I’ll try to do another search, but a pointer to a newer release is very welcome.

Yes, Intel Q670 paired with the non-vPro Intel AX211 PHY. Yeah, I thought all the AMT systems with WLAN had the full vPro and annoyed me quite a bit when I checked the part number. I can’t believe they did it to save some 6$, but on the other hand I don’t think they really maintain two different FW updates for such a small difference. In fact I checked the available downloads from HP and they are the exact same softpaq bios file for both the elite 600 (ISM) and the 800 (AMT), regardless. By the way, ISM supports remote management via WLAN starting with Alder Lake/CSME 16, so I would expect to be always there/enabled.

Also, I checked the dump with UEFITool and I can see in one of the ME (Boot) partitions the WLAN microcode and a binary named “wlan_drv”. What else can I check? Would I need to clear something else before upgrading? I have noticed that disk/memory upgrades are not refected in the AMT inventory (without un-provisioning first?). What would you suggest doing?

Thanks!

PCH is not supported seems to be more than a version conflict? Post a screenshot of the output / the command window.

Hi, sorry for the delay, a few things got in the way this week… and sorry, contrary to my believe I didn’t have the drivers installed, now it works. It also worked under Linux. I also have the output file for the Elite 600, which is effectively the exact same flash image but configured with ISM. Both are i5-12500T, Lan i219-LM, Q670 stepping B0, both with non-Vpro AX211.

I am quite sure now that it would work, at the very least when the OS is running.

Well, no experience with wireless for newer ME versions, but I don’t see anything that’s missing? Did you check the wireless firmware entry in FIT when decomposing? (Wireless compatibility depends on existing firmware in ME for corresponding wireless generation)

I’d just buy one module and try, they aren’t too expensive?

.
With installed WLAN card and firmware mismatch this was mentioned in MEInfo 14 at least:

(Why is one machine just ISM?)

safari · August 9, 2023, 9:35pm

One machine is just ISM because HP tries to squezee more money by selling the same product under two different model names, and the AMT one for a premium. They seem to have the same identical ME code, and indeed ISM should now support wi-fi as well starting from this generation. Yes, I think I’ll end up buying and reporting back for the record, but I wanted to have a second opinion first and make sure nothing would break.

Here it says “Solar”, which is the latest codename appeared in the ucode for Linux, so it should refer to the latest AX211/AX411 radio. Also, CLINK is enabled and IIRC is the SMBus used for reporting the vPro capabilities of the module.

UEFITool shows a wlan_drv and the microcode, so I guess nothing should prevent it from working. I’ll go ahead with the purchase and let you know!

The question was if it’s hardware (chipset / processor) or ME config where they restricted capabilities. ME config can quite easily be changed.

safari · August 10, 2023, 12:41pm

No, the rest is vPro capable on both (and indeed work), just the radio module. About changing the config on these… despite Sure Start it should work, but I tried shorting the FDO pad and couldn’t rewrite the ME section. Both flash are also a wson-8 package, so not as frictionless.
Anyway, thank you for your help I will come back with any update once I receive the modules.

safari · September 22, 2023, 9:45pm

For the record, AMT/ISM over WiFi works perfectly after swapping the radio module with the vPro part on both PCs. Thanks everybody for helping!

Thanks for the feecback!
