Does someone have this motherboard bios that is ready to write on the IC?

Hi I'm working on that asrock motherboard. It had shoted mosfet on cpu phase(changed) and 1 cap on bottom side(changed). Led driver is probably shotted too because voltage on one leg of this chip is 0.5v to 5v (its in loop rising and falling) its's RT7905 and i cant find datasheet :/ But its only led driver so mb should work without it. When i desolder it on the same leg is 5v all the time.
If i start mb on all cpu phases is 1v1 for a few seconds only. Other voltage are present. So i tried to flash bios with the newest on official site and it doesnt help. Its not normal extension... -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight

Hello everyone,
I’m looking for a full raw 16 MB BIOS dump for an ASRock Z790-CX (DDR5) motherboard.
The board powers on (fans spin, RGB lights on, RAM LEDs active), but there is no display output and the VGA and BOOT LEDs stay lit.
I’m using an Intel i9-14900KF CPU (14th gen), and it seems the BIOS version on my board doesn’t support it yet. I tried to flash the official ASRock BIOS file (renamed .ROM → .BIN) directly using my RT809H programmer, but it didn’t work — monitor stays on but with black screen, so I believe the ASRock update file is not a complete... -
Hi, need help here.

Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...
