Firmware for a Kiano tablet supplied as a 2.35 MB RAR archive; the name mentions a PM model fragment, the AXP288 power management chip and a 25Q64FV flash memory, which is a 64 Mbit (8 MB) Winbond SPI part. Knowing the flash type lets you choose the correct setting in programmer software before reading or writing. Typical use is reviving a tablet stuck on the logo or with corrupted BIOS. Check the chip marking on your unit matches, and always read and store the original contents before flashing.</description>
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
