If you can flash internally from an OS depends mostly on the configu-
ration of the chipset done by the BIOS. Likely only possible if there
is an explicit option in the BIOS setup to disable flash protections.

You can always try to run flashrom to see the actual configuration.
Though, for mobile devices it needs an ugly switch (have a look for
`force_I_want_a_brick` in the flashrom manual page). That switch
sounds scary because older laptops really had problems, even if you
only probed the flash chip. It's not that dangerous on a modern sys-
tem.

The alternative is to access the flash chip physically, like Mike
described.

If you get access to the flash chip, you'll also need a valid BIOS
file (not just an update).

What chip? never heard that Microsoft would manufacture chips.
