Board & Goal:
ASUS N752VX rev 2.0 (i7-6700HQ, HM170 PCH, Winbond W25Q64FV SPI flash)
Rebuild full 8 MB SPI image: Intel Flash Descriptor + ME 11.8 (1.5 MB RGN) + BIOS region from N752VXAS.303
Tools & Files:
- Intel CSME System Tools v11 r39 → Flash Image Tool (FIT)
- Clean ME 11.8.50.3399_CON_H_DA_PRD_RGN.bin
- Extracted
N752VX_BIOS_region.bin(~6 MB) via UEFITool NE - CH341A programmer & SOIC-8 clip
Steps Taken
- Extracted BIOS region from N752VXAS.303 in UEFITool NE (“Extract body”).
- In FIT:
- Selected “Intel (R) H Series” → “HM170-Mobile” from dropdowns
- Loaded ME RGN into Intel ME Region
- Loaded extracted BIOS into BIOS Region
- Disabled GbE, PDR, EC regions
- Set Flash Components = 1×8 MB
- Built image (outimage.bin)
- Flashed outimage.bin to W25Q64FV via CH341A; verify passed.
- Result: fans spin endlessly, no POST, no video output.
- UEFITool NE inspection shows Descriptor region is entirely 0xFF (no 0x5AA5F00F signature), shifted.
Attempts & Observations
- OEM Section import of descriptor binary from forum dumps only shifted signature further.
- No original backup available.
- Manual editing in HxD unviable without valid descriptor block.
- PlatformConfiguration XML templates not found in GitHub-only FIT distribution.
Request
CHATGPT tells me that i need reliable source for full Intel CSME System Tools v11 (including SKL_H_HM170.xml) or a working sample platform XML. Objective: inject valid Flash Descriptor at 0x0000–0x0FFF so CPU recognizes ME and BIOS regions and system will POST. The one on github doesnt have this file and i was thinking Fit doesnt need that file because it already has a configuration selected from the topdown menus at the top.
