BIOS firmware for the Acer Aspire 1830TZ, built on Wistron board JV10-CS. Wistron uses project codes like this for the Acer motherboards it manufactures, and the code is usually printed near a board edge. The RAR package is 1.64 MB and is meant for reprogramming the SPI flash directly when the laptop shows power but no image. Match the board code first, read and archive the original chip contents, and confirm the image size equals the chip capacity before writing it.
