I'm stuck on a BIOS password issue on an industrial embedded PC and would really appreciate some expert eyes on this. I've done what I can with hex editing but I think the real password check is elsewhere in the firmware, beyond my current skill level.

Hardware:

Device: Advantech UNO-1372G-J (industrial fanless PC / OPC)
Motherboard: UNOB-2117MB REV.A1, made in Taiwan, PN 19A3211703-01
CPU: Intel (embedded SoC, soldered)
Main BIOS flash chip: Winbond W25Q64JW (8MB, SOIC-8, 1.8V)

Problem:
The BIOS requires a password at boot/setup entry. Clearing CMOS (battery pull + CN36 clear-CMOS jumper + shorting battery socket V+/V-) has no effect on the password — as expected, since on these AMI Aptio boards it's stored in SPI flash rather than battery-backed CMOS.

What I've tried so far:

Dumped the main BIOS chip (W25Q64JW) via CH341A + 1.8V adapter + SOIC-8 clip. Read 3 times, MD5-verified identical each time.
Located what appears to be the AMI TSE (Total Setup Edition) password-related NVAR variables in the dump:

AMITSESetup NVAR entry (offset ~0x300281) with all-zero data (looks like a "default/empty" instance)
A second AMITSESetup NVAR entry (offset ~0x302931, size 0x68) containing non-zero data — what I assumed to be password hash material (80 bytes, structured as two overlapping ~40-byte sequences)
An OEMDEFAULTPWDSetup NVAR entry (offset ~0x302999) with a single data byte (0x04, later noticed value 0x70 depending on offset interpretation — I may have made an error here)

Tried zeroing the 64 then 80 bytes of the suspected hash data in the second AMITSESetup NVAR — reflashed, no change, password still requested.
Tried invalidating the NVAR entries entirely by changing the state byte from FF FF FF to 3C FF FF on both AMITSESetup and OEMDEFAULTPWDSetup entries — reflashed, verified the re-dump matched the written image exactly (MD5 identical), so the write itself succeeded with no write-protection issue — but the password prompt is still there.

So the chip write/erase/verify cycle works fine (no WP/lock issue), but neither approach neutralizes the actual password check. My guess is either:

The AMITSESetup varstore I found is just the general Setup form storage (all BIOS settings), not specifically the password, and the real password hash is stored/checked elsewhere (different GUID, different NVAR name, or computed by DXE/PEI driver code rather than a plain stored hash)
There's some checksum/CRC over the NVRAM volume that needs to be recalculated after modification, and an invalid checksum causes the driver to fall back to a "locked" state rather than "no password"

What I'm hoping for:

Guidance on identifying the correct NVAR GUID/variable that AMI Aptio uses for password verification, as opposed to general Setup storage
Whether AMIBCP (AMI BIOS Configuration Program) can open/patch this dump properly, since UEFITool NE reports "Stores not found" on this image
Any known quirks specific to Advantech's AMI Aptio implementation

I have the original untouched dump and full change logs for every attempt. Happy to upload the original .bin if that helps, and I can provide any additional dumps/photos of the board on request.

Thanks in advance for any pointers!]]>

Hi all, I know this board is mainly for unlock requests, but I couldn't find as active an Insyde-specific board elsewhere, and I'm hoping someone here might recognise this. Apologies if it's not the right fit.
Background: Battery was accidentally disconnected during a BIOS update via HP Support Assistant, mid-flash from F.40 → F.42. Laptop now fails with "System BIOS recovery failed / Unable to open BIOS image file," and standard USB crisis recovery (Win+B) with a fresh F.40 SoftPaq from HP fails the same way.

Specs:

HP Envy 17-cg1001na (30A27EA#ABU)
Chip: 16MB
Board ID: 8823
BIOS: InsydeH2O

What I've got:

A dump of the corrupted chip contents, which still contains F.42 data
The clean F.40 SoftPaq downloaded from HP

What I've tried: A few manually-patched combinations of the corrupted dump and clean F.40 file. Results have been inconsistent — some versions give no power at all, others power on and blink the caps lock LED (haven't decoded the pattern yet), none have booted to Windows.
Most recent attempt: Using HxD, found a $Bin08822 marker in the corrupted dump, located the matching point in the clean HP file, and manually spliced that section across. Also opened both files in UEFITool 0.28.0 — found several "08822" text matches, one inside what looks like a driver/PE32 module, and one inside the ME region (which I'm avoiding). Not confident I've found the right target.

I'm working via desoldering/resoldering the chip rather than a clip, so each attempt has real cost — would really appreciate anyone with Insyde/HP experience taking a look before I commit to another write. Happy to share both files.]]>

Tests already performed:
-Reinstalled the original i3-2310M CPU.
-Tested with a brand new keyboard.
-Tested with the keyboard disconnected.
-Tested with two different Wi-Fi cards.
-Reset BIOS defaults.
-Removed CMOS battery.
-Reinstalled drivers.

Status:
-Internal keyboard does not work, even in BIOS.
-USB keyboard works normally.
-Wi-Fi cards are detected by Windows, but remain hardware disabled.

Could this be related to BIOS/firmware corruption or some firmware state triggered by the CPU upgrade?
Is there any way to force a complete BIOS reflash? Reflash the same BIOS version (A12)? Or use a modified BIOS to bypass Dell restrictions?
