Where did you get the ROM from? I presume it's from prema's website, but that appears to be totally borked right now. Could you possibly post the file here, or PM it to me, if you still have it?

I posed about this here, but never got a reply: I upgraded the GPU in my Clevo P151HM1 some time ago to a K4000M. The machine does boot into the operating system, but the BIOS seems to have some sort of disagreement with the card and as a result I can no longer get in to the BIOS setup screens unless I go swap the old GPU back in. Is a modified K4000M BIOS available to work around this issue?

I would actually like to amend my suggestion of Hamachi to ZeroTier One. ZeroTier One is basically an open source version of Hamachi that supports more devices per network (100 instead of 5 at the free tier) as well as more devices - windows, linux, osx, android, iOS, various NAS devices, and even OpenWRT. It also supports ipv6, which may be interesting to some people. I recently converted all of my devices over to ZeroTier One and performs exactly like Hamachi, just without the pesky 5 device limit.

Depends on what's on the motherboard. Also, I presume the chip on the motherboard is replaceable -- wi-fi cards are rarely fully integrated into desktop or even laptop motherboards to simplify the board design and simplify regulatory requirements. If the unit on the motherboard can be replaced, then that would probably be a better idea than adding an extra card, be it PCIe or USB. Depending on what card is currently installed and what wi-fi router/access point you're using, you may or may not see any improvement by upgrading the card. Newer cards do support more efficient methods for utilizing the spectrum, but the router/access point you're connecting to also needs to support this. And even then, you may not see any improvement if the bottleneck is your internet connection.

I would actually recommend using Hamachi. The free version lets you make networks with up to 5 computers and it doesn't require static IP addresses, DNS/DDNS, DMZ, etc. And you can run it as a service in linux, which is very nice for low-power NAS setups.

Thread in question is here: http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/ One more important thing to note: even if the GPU dies are "the same", they could well be binned based on performance/defects. So even though this sort of a mod might look good on paper, whether it works on any particular card could be a crapshoot, especially if you want to try this and then try overclocking it.

I think you need to change the PCI ID, reflashing the BIOS is not enough. This is set by resistors on the board, moving them around and swapping them out can change the PCI ID. There was a thread about it on the EEV blog, I think. Might be worth looking at. I don't think they looked at any laptop GPUs, though, so you may need to do some work to find the correct resistors to swap.

I did see a thread over on the EEV blog about switching GPU PCI device IDs by changing around the resistors on the card. However, they were most interested in going the other way (GTX -> Quadro) and I don't think they looked at any laptop form factor cards. So it's probably doable, but you would have to figure out what resistors to move around and/or replace. After that, I think you just have to install the correct driver.

Yeah, that's pretty much what I figured, and why I posted here. Also, there are a whole bunch of these cards on ebay right now for $100-150 or so. If it is possible to get this working nicely, then that could be a nice upgrade for people who want to get some more life out of their P15xHM laptops.

I just got a Dell Quadro K4000M to install in my Clevo P151HM1, replacing a Clevo GTX 480M that has been developing issues. However, there seems to be a minor compatibility issue between the system BIOS and the card BIOS. On POST, the machine pauses for a couple of minutes and beeps a few times before booting the OS. After booting the OS, the card seems to work fine, except the PCI subsystem ID is not correct - should be 1028:153F (there are references to this in the VBIOS dump), but the Clevo BIOS appears to rewrite this to 1558:0000. Interestingly, the drivers from NVIDIA ignore the subsystem ID, so no INF modifications were necessary and the card works correctly in both Linux and Windows. The long POST would just be an annoyance, save for the fact that I cannot get into the BIOS setup and boot device selection screens anymore. The computer is running the latest BIOS from Clevo. I believe the solution would be a mod to the card's VBIOS, however I am not sure exactly what has to be done. The card has BIOS version 80.04.5A.00.02, which can be downloaded here: http://www.techpowerup.com/vgabios/145048/145048.html (I didn't upload this, but GPU-Z says that's what I have on my card). This post seems to reference the exact same issue, except for a different card: https://forum.techinferno.com/index.php?/forums/topic/7617-p150hm-with-gtx-670mx-not-booting-normally/. Does anyone know if this compatibility issue can be worked around?
