2.1 0.19 Ch341a ((top)): Neoprogrammer
The CH341A has a yellow jumper (usually marked as P/S). For programming motherboard BIOS or SPI Flash chips (25 series) and EEPROMs (24 series), the jumper must be set to (connecting pins 1 and 2). 2. Chip Orientation in the ZIF Socket

NeoProgrammer is a modified, improved version of the open-source utility. It is developed to address compatibility issues with modern flash chips, provide better automatic detection, and offer a more stable user experience for CH341A users. NeoProgrammer 2.1 0.19 is particularly favored for:
The CH341PAR driver is missing or corrupted. Reinstall the driver and try a different USB port (preferably a USB 2.0 port on the back of the PC). "Unknown IC" or Detection Fails Chip Orientation in the ZIF Socket : Install
is the most reliable, feature-packed alternative software for the ubiquitous CH341A USB hardware programmer . While the cheap, black-and-gold CH341A hardware remains a staple for recovering bricked motherboards, flashing router firmware, and modding GPUs, its stock manufacturer software is notoriously buggy, outdated, and lacks support for newer low-voltage ICs. NeoProgrammer 2.1.0.19 resolves these pain points by offering an expanded chip database, built-in structural bypasses for voltage detection, and lightning-fast verification protocols.
