Staged update process
To install version 1.25.0.0 is an act of courage uniquely mundane. It requires a FAT32-formatted USB drive, a prayer to the gods of stable electricity, and the willingness to accept that if something goes wrong, the motherboard will turn into a $300 paperweight. Bricking a device during a BIOS update is a uniquely modern tragedy: the machine is not broken in a physical sense—the capacitors are fine, the solder joints are shiny—yet the knowledge of how to wake up has been erased. Thus, 1.25.0.0 sits on a knife's edge. It offers the promise of stability, support for a faster NVMe drive, or compatibility with a new generation of graphics card, but only if the user dares to perform the digital equivalent of open-heart surgery while the heart is still beating.
