Thank you so much [USER="457801"]rex98[/USER]! I was able to successfully restore this system using those 2 files. A big thank you to [USER="237374"]SMDFlea[/USER] for pointing me in the right direction and all others who looked and helped

Thank you so much🤝! I'll try this tomorrow morning and report back.
I've been using NeoProgrammer primarily but used AsProgrammer for the w25r256JV chip as NeoProgrammer did not have this IC specifically. I have found an updated IC database and will use NeoProgrammer moving forward.
Question regarding clip vs. adapter, for adapter you mean de-soldering the chip and mounting in dedicated flash adapter board or socket right? I agree this is ideal however currently I don't have access to a heatgun so de-solder/res-solder surface mount is not something I can perform....
Update: Some progress, I found a confirmed working unlocked BIOS [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-desktop-motherboards-graphics-cards-and-pc-peripherals/bios-schematic-requests/72826-need-optiplex-7010-bios-dump?p=3530617#post3530617"]from this thread/post[/URL] for the W25Q128JV chip
I performed the following:[LIST=1][*]Removed CMOS battery, read back W25Q128JV chip - strangely it did not match the Original.bin that I had flashed back and verified in OP[*]Erased chip, verified ZEROs[*]Flash patched...
Got the pogo header wire and read the 25R256JV chip, this was much more difficult vs clip as it had to be handheld in place. The CR2032 battery and all power sources were removed from board/system. Read with AsProgrammer and my CH341a @3.3v per spec[LIST=1][*]First attempt: attached "as w25r256 first read.zip", [B]CRC32 = 0xDE6E1D19[/B] - Note: this however fails at verification (read back) at address 0x0102DE75[*]I repeated until VERIFIED successful[*]4th attempt: attached "as w25r256 4th read VERIFIED.zip", CRC32 = 0x48E4F159 - [B]successfully verified[/B][/LIST]I attached...
Happy holidays! Rats I realized what you mean by SOP8 clip won't work as the it's a flat surface mount without side legs like the 25Q128JV chip.
I looked up the datasheet of 25R256JV and it appears similar in electrical specs and I believe my CH341a programmer should still work with the right adapter. I also verified ASProgramer v2.04 has this IC in supported list.
I found this pogo adapter for WSON8 6mm x 8mm [URL="https://www.amazon.com/MORIENZI-Circuit-Programming-Programmer-EZP2019/dp/B0CJQ8KQK2/137-6891457-2164163?pd_rd_w=ojxZO&content-id=amzn1.sym.53b72ea0-a439-4b9d-9319-7c2ee5c88973&pf_rd_p=53b72ea0-a439-4b9d-9319-7c2ee5c88973&pf_rd_r=XXJ4M12BSBXXK7FY17KV&pd_rd_wg=5CPJz&pd_rd_r=8a16d1d8-f2b6-4724-8f05-0f8c5b7e6b81&pd_rd_i=B0CJQ8KQK2&psc=1"]Amazon...
Thank you for helping, I'm not familiar with 2 BIOS systems, I've attached a photo of the system board[LIST=1][*]The smaller Winbond 25Q128JV chip on left of the battery is where I got the original bios and flashed patched BIOS to.[*]The slightly larger Winbond 25R256JV chip could be the ESME? I did not do any modification to this chip[/LIST]I downloaded the original BIOS update file from Dell and noticed it's a 128MB file, far larger than just a 16MB BIOS chip would require.
Let me know if I can provide any additional info.
Thank you for helping, I'm not familiar with 2 BIOS systems,
I got a Dell Optiplex 7010 micro PC ([URL="https://www.dell.com/support/home/en-us/product-support/product/optiplex-7010-micro/overview"]Exact Model[/URL]) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/109990-dell-8fc8-bios-password-patcher[/url]
After flashing the patched the BIOS, the PC is unresponsive with a solid...
