Hi all.
I came across a strange phenomenon.
The short question is that all "user" sections cannot be rewritten even with a generic flasher.
My new laptop came with Windows 8 preinstalled.
Obviously it has a Windows 8 product key embedded "somewhere" because it does not require me to enter a key even when I use a retail (not recovery) disc for clean reinstallation of Windows and RWEverything always shows as an MSDM report an identical single key.
I recently disassembled my laptop to find the bios chip directly soldered on the system board. The IC is a Winbond W25Q64BVSSIG and has a capacity of 64 Mbit (8 MB).
The laptop manufacturer has released a bios update for my one and it can be expanded into several files including a .rom (size: 8,388,608 bytes) and a Windows flasher.
The rom size was found exactly equal to 8.00 MB and I wanted to rewrite ALL sections (just out of interest or curiosity).
The most reliable method for that would be romoving the bios chip from the mainboard to reprogram it on an IC programmer connected with a pc. Unfortunately the chip is not socketted and I do not have a skill to desolder the 1/5 inch sq chip however (but have a friend ready to help me recover it if it bricked).
So I then downloaded a dos flasher and gave it try with a "(program) ALL" option. Flashing itself successful and the product key keeps as before however...
Why does the flasher know the MSDM table?
Why is the rom size exactly the same as the chip capacity though it does not be replaced entirely with the old one?
Thanx!
