BIOS package in a 3.04 MB zip archive for the Jumper EZpad 5S tablet, with the name listing the SR29Z processor stepping code, the AXP288C power management IC and the ALC5651 audio codec. Those component markings help confirm that the dump matches the tablet revision on the bench, since budget Atom tablets often ship with different parts under one model name. Extract the image, check its size against the SPI flash fitted on the board, and back up the original chip with a programmer before writing anything to it.</description>
