Plug your CH341A programmer into a USB slot. The status bar at the bottom of the software should turn from red to green, indicating the hardware is detected. How to Flash a Chip Safely
Click and select your newly acquired firmware or decrypted clean BIOS dump file. Next, click Write IC (or use the automated "Auto" feature sequence) to flash the code onto the chip. Step 6: Final Verification

While version is a recognized older build, the software has since seen several "free updates" to maintain compatibility with newer hardware: Programming ENE KB90xx chips with the CH341A Plug your CH341A programmer into a USB slot
: Offers granular Status Register (SREG) editing, including the ability to toggle the Quad Enable (QE) bit safely.
The software now supports 1629 chips (and even more with the latest patch), spanning SPI NOR Flash, SPI NAND Flash (experimental), SPI EEPROMs (25xxx, 95xxx, 45xxx), I²C EEPROMs (24Cxx), MicroWire EEPROMs (93Cxx), AVR MCUs (ATmega, ATtiny), NUVOTON MCUs (N76E003), ENE KB90xx, and many others. This extensive coverage ensures that even relatively new or less common memory chips can be programmed without having to search for obscure third‑party tools. Next, click Write IC (or use the automated

: This indicates loose physical contact. SOP8 test clips are prone to slipping or picking up oxidation from the chip legs. Clean the target contacts with isopropyl alcohol, reseat the clip firmly, and attempt the read/write sequence again.
Several trusted sources provide the NeoProgrammer v2.2.0.10 package. Here are some of the most reliable ones:
The update introduces the ability to skip writing null (0xFF) bytes during programming, which can dramatically accelerate the writing process when large parts of the flash are already empty. This is especially useful for BIOS and firmware updates where only a portion of the memory needs to be changed.
