Just spent an "interesting" (to put it mildly!) weekend on this project to
enable a microprocessor upgrade. I wouldn't recommend it for the
faint-hearted, suffice it to say, or you might end up with a paperweight.
:-)

You know, it wouldn't be quite so bad, except that in some cases, there is
no reverse path available (i..e, it's a one way trip) - which seems
unforgiveable, on their part!

My question is: why do these BIOS manufacturers sometimes make it so damn
difficult to upgrade/downgrade or go back to a previous version (especially
when going from one manufacturer to one its subsidiaries, or vice versa
(like Dell and Intel)?

And not only that, but even block certain upgrades with certain chips, just
out of self-centered arrogance on their part (and not due to real chip
limitations)?
