It has the q150 chipset and I think there are not any newer lenovo pc's that are using the q250 chipset. Do you think it is possible to mod that thing for coffee lake? M800 SFF or tower ? It should work on those as BIOS looks same as M700/900 BUT use a EPROM flasher so you can try and go back if things go wrong DON'T use SW flasher as there's a chance you'll need to buy an EPROM programmer incase that goes wrong So what I did should work for you too, but I can't guarantee that Quote Link to post Share on other sites

I'm happy to buy one and experiment. Quote Link to post Share on other sites

Things coming from China aren't too bad in NZ, no longer than it used to take Grab latest BIOS, there is a newer one than what I worked on flash that to your machine the go through process Quote Link to post Share on other sites

Did everything and it's workin fine, much better than the G4400 It wasn't recognized the sata drive, that was the only problem I had, and crying for the unknown uuid, which I'd really like to solve, but I don't know how to yet. I opened the bios and changed that "os defaults etc" option to enable and it booted up fine, however since then I can not access bios at all. If I press the buttons on the keyboard to access bios it just won't boot, no video at all. Edited March 22 by cicistrici Quote Link to post Share on other sites

The only issue I have is that the sata device is not shown in bios but it is booting and I can access bios now which is great. Also it seems that the merged bios keeps the original mac address of your device. If you want to change the UUID and other things which are not kept in the edited bios, you just have to create a bootable DOS usb disk, then take a look at here And you can easily edit what is unknown.

cicistrici 0 Posted March 24 Report Share Posted March 24 (edited) Hi @mobilenvidia I read that you don't use wifi, but I have a strange issue and you might have something helpful. Originally my unit does not have wireless installed, so I got an m.2 ngff wireless card which is totally supported by my machine, even the same FRU as in the Lenovo documents for this PC. But when it is installed, the pc just refuse to boot, fan spins at almost max speed, no video nothing. Of course after it is removed it boots just fine. Edit: Ok, it was just a connection error, now it boots but the device is neither shown in the self test and nor in windows. Edited March 24 by cicistrici Quote Link to post Share on other sites
mobilenvidia 0 Posted March 24 Author Report Share Posted March 24 Does the card still work ? When connecting wrongly you didn't short it ? Quote Link to post Share on other sites

It works well in a laptop. I found another card which also has an FRU. Now if I install the Intel card it boots up fine, but it can't be found anywhere. If I install the other card, which is a Realtek one the fan spins but no boot. I had the opportunity to test another card, it was also an Intel one, but got no boot with that too. Maybe Lenovo disabled the ability to add an m2 wireless on pc's shipped without one? I do not know yet, if I'll have some more time I think I'll swap to the old cpu and flash back the original BIOS and then check if it is working.

You need to connect some pads together and isolate some others Coffeetime app has a picture of what to do there. You'll need some things to do it, and make sure you do good job as you can fry your Mobo and/or CPU Quote Link to post Share on other sites
rycyve 0 Posted April 24 Report Share Posted April 24 (edited) hi mobilenvidia! would need help. i want my m900 tiny to run i7700. for some reason it only works with mod m900 m910 clk.bin bios but if i take m900 backup.bin biose and change it to coffeetime 0.92 then no picture will come up. can't understand what's wrong? I'll upload images here. Edited April 24 by rycyve Quote Link to post Share on other sites
mobilenvidia 0 Posted April 27 Author Report Share Posted April 27 You don't need to run Coffeetime if running a Kaby Lake CPU you won't gain anything You just need to get to M910, via the BIOS merge It should work as long as you have the Code in the BIOS, make sure its not a ES CPU also not a non T, but M910 should be your aim with the 7700(T) Quote Link to post Share on other sites
rycyve 0 Posted April 28 Report Share Posted April 28 (edited) thanks for the reply.cpu is genuie i7 7700. i just want m900 biost because it would fit better in tiny.m910 bios makes this B750 having a video card menu which i don't want. that is already one of the reasons. i don't understand what is missing is vbios + gop, ME are the same and the microcode is on this cpu 906E9.i think the thing is still ME.910 already has kbl support though ver. is the same as 900 but somewhere there is something else in the oem bios. if i try a newer version of ME or take the 910 image from ME and write it in the 900 bios.

mobilenvidia 0 Posted April 28 Author Report Share Posted April 28 Coffeetime only works with KabyLake capable Mobo's/BIOS's Lenovo has crippled the M900 in the BIOS (hidden) to not accept Kabylake CPUs And so the step from M900 to M910 has to be made, you can't get round it I found (I think been so long now) not to update the ME FW worked best I too have some issues at boot where sometimes it goes through the trying to boot via LAN IPv4 and IPv6 makes boot rather slow but I have the M900 on 24/7 so only issue when Windows updates But other than that its running great Am impressed the 65w CPU works, I may keep an eye on higher watt CPUs for my baby 4k/60, HEVC encoded video is a struggle for poor old i3-9100T, which is about an equivalent of a 6500T/7500T but with newer features, so they would probably struggle too Quote Link to post Share on other sites
rycyve 0 Posted April 28 Report Share Posted April 28 (edited) 568 / 5000 I think lenovo has divided the m900 biose ME into several, so the bios update in the form of 8mb does not guarantee an ME update, it's not just in this section of the biose. anyway, I'm still working on it. both DP ports are booting. everything works but i want to complete the fact that the m900 bios works in kbl. further, the memories need to be unlocked to run at full speed, i.e. 3200MHz not def. 2400MHz anyway, I'm working on it. thanks for replying and if you have any ideas on how to more easily open the biose submenus or activate them, any suggestions are welcome.

mobilenvidia 0 Posted April 29 Author Report Share Posted April 29 I'm not in the fussed camp about ME, and yes Lenovo has the ME hidden in some BIOS updates where it probably as special routines to recognise it and update The 7700 maxes out at 2400Mhz DDR4 ? I need to add a 2nd 8GB stick to dual channel and help with my 4k/60 decoding All I care about is it works with some quirks I can live with But most interested in how you get on The M900/700 spanning 4 generations of CPUs is pretty cool Quote Link to post Share on other sites
rycyve 0 Posted April 29 Report Share Posted April 29 yes the 7700 officially supports 2400MHz but this is the case with every cpu but you can always get more memory speed if there are corresponding memories. i bought lexar 2x8 GB DDR4 3200 MHz LD4AS008G-R3200GSST because they are affordable and very good with samsung chips which are oc favorites. here's an overview of analog chips https://www.pctestbench.com/lexar-ddr4-2666-sodimm-laptop-memory-review/3/ . i am using this kind of active dp to hdmi adapter because this manufacturer has paid the license fees and works very well and also the price is ok https://www.startech.com/en-us/audio-video-products/dp2hd4k60s . the cooling is such a story that the tiny oem cooler is 35w rated and can't be over or converted to do anything with the software but the cool cpu can't. but no problem after a long search i still found a chiller from the chinese manufacturer which is 65w and it is already in my order.there are two places where you can order it. I bought a cheaper one because the delivery time is practically the same.https://www.chinahao.com/product/543645905415/ https://www.yoycart.com/Product/543645905415/ Quote Link to post Share on other sites
mobilenvidia 0 Posted April 29 Author Report Share Posted April 29 Nice find on those coolers, I may need one on a work M92 which gets very toasty not doing anything Been toying taking out the i5 and putting in a Pentium as it just records data logs from a Sensor You are asking a lot from 1lt machine, with OCing memory bus (if that will even work) Be happy with 2400Mhz dual channel, 3200Mhz won't see anything but a place to keep you coffee hot I bought this Active DP to HDMI converter https://www.pbtech.co.nz/product/ADPJ5C3158/J5create-JDA158-DisplayPort-to-4K-60Hz-HDMI-Active Works well and was cheap and in NZ no waiting weeks or months from China at the moment My AV Amp is only 1080p, and running above converter to 4k60 TV and another to the amp for sound was problematic As M900 got confused with dual displays and when amp going into standby it would scramble the TV displlay I need to either get a 4k60 AV amp or preferably a nice stereo amp as I have a DAC coming from Aliexpress Quote Link to post Share on other sites
