I will do my very best.

The bad thing is that vendors like Compaq respectively HP and some others,
in particular Sony, do not provide vendor flashing tools which can be used
without putting an unwanted operating system on the machine.

In former times it was usual that one was able to flash a BIOS after booting from
a DOS boot floppy and everything was running quite well. Now one needs a gra-
phical  user interface to be able to click on the "OK" button just to proceed a
BIOS flash. This brings perversion to a climax, doesn't it? And where do we want
be be tomorrow?
