Dell Precision T7910 no bios, no post after applying SAS/RAID setup
Hi,
My Dell Precision T7910 died after enabling onboard SAS controller and applying RAID settings. There were no hardware changes between working and not working state, only setup (via bios -> controller settings). After applying settings and reboot PC turns on, flash leds (normally) but there's no further action, it just stays on with no graphics and no keyboard led's on. There's no Dell logo, nothing. I've tried resetting bios by jumper, replacing cpu's, replacing ram, removed/replaced cmos battery, disconnecting all drives etc. I've also dumped .bins from mobo chips SLI1 (16 mb file, chip MX25L12873F) and UL3 (4mb file, chip MX25L3206E), bigger one (SLI1 16mb) as far as I found on the internet should be the one with bios, no idea what UL3 is
. I've extracted bin files from dell's exe bios updaters (via Dell PFS extractor) but they are completely different comparing to the dumped from mobo's chip. I also used MEAnalyzer to see if it contains Intel ME - original one has it, extracted from dell's bios exe does not (file called 1 -- 4 Intel Management Engine Update v9.1.2.1010.bin has it - same version). Can anyone look at this and tell me what should I do with this? I have completely no idea what I'm doing honestly 
.
