Hi everyone!
I have a customer (actually the local university) that brought me a [B]NUCS BOX-155H[/B] that is trying to turn on (fan spins for a sec) but fails. Unfortunately I only have the motherboard so no serial number - they already used just the motherboard inside a project car or something that they are developing (I can provide pictures if necessary).
I would like to see if the BIOS is intact so I have uploaded here a dump (there are two chips) - there is no file available in the website - the system is probably too recent.
Please assist me in repairing...

you are right! i did search though using motherboard code and didn't get results (maybe I used google only?) - I was happy to also post all details etc this time but still made a mistake

ok today I even tried to write ST with cctk under WinPE and that wont stick either... I get some error message and ST is not saved
error "CoCreateInstance() failed for locatorGetWMISMBIOSTable: NULL pointer to SMBIOS Entry specified.GetWMISMBIOSVersion: null pointer passed as pSmbios."
I am depressed.

unfortunately this also causes the same behavior i.e. white led on->off->repeat only difference I now have full fan spin which your previous files didn't bring up (noticed that when a bios gives image the fan is indeed spinning fast so this is normal).
I tried the "working but not saving" bios I mentioned before, then downloaded the official bios from DELL, flashed it using a USB which completed successfully and NOTHING CHANGED... Im going to hang myself in the lab (soldering disoldering the chip one of the legs broke and I had to use the grinder, resolder it under...Leave a comment:

unfortunately I get the same - white led on -> off -> repeat... but I found a working set 8/16mb (everything works: keyboard, trackpad, nvme) but it won't save the Service Tag and keeps turning on to Manufacturing Mode.
is it possible to:
1) make it save ST
2) transfer bitlocker keys from original non-working dump? now that it sees the nvme it asks for bitlocker key, the owner didn't know they had bitlocker enabled
attached is the "semi"-working bios
thank you so much for your efforts guys, I'd be happy to buy beers!...Leave a comment:

ok just tried them but I get no image, fan came on a couple of minutes later, the power led turns on white, stays for a few secs and fades out, repeat - caps lock led also on all the time.

hi from me too!
I mistakenly posted this in the wrong thread (different model) so here we go:
can you please repair this bios dump? gives backlight and nothing else - there is bitlocker on the sdd so maybe we can save the data
ST: 5ST4P93
EX: 12625892823
motherboard: 19862-1
It must be Vostro 5502 (the damn thing has not "model" label so I uploaded a pic)
I tried other dumps (from 5406/7502 I think as I was in that thread earlier), a few would not save the ST or exit manuf. mode and one from above that worked...Leave a comment:

it is a Vostro indeed and the motherboard is 19862-1... I will head to the correct topic apologies for the mistake I got here because of the no-saving of service tag and similar board code (the bios given here also worked to fuel my confusion even further!)
thank you
"The [B]Inspiron 5406[/B] has different EC firmware to the [B]Vostro 5502[/B]"
I am too tired or just an idiot. thank you again.it is a Vostro indeed and the motherboard is 19862-1... I will head to the correct topic apologies for the mistake I got here because of the no-saving of serviceLeave a comment:

Toshiba P50W-C-10V (TRKU 2.1) dump needed
Hi guys!
A friend of mine accidentally overwrote a 4mb file to this one (instead of a 8mb) without taking a backup of the original. I have searched everything from North to South pole of the world wide web and all the files I found just do not work. I also downloaded v1.20, 5.00, 5.10 from the official site and trimmed them to 8mb (8192kb) and there are some signs of life but no post. To be more specific version 5.10 did not look like the others in HxD and altough it could be trimmed to 8192kb after removing anything after 4FFFF0 there is zero reaction to the PSU or fan like the others.... -
