Wow, what planet are you from? Don't look now but your egocentricity and
ignorance are showing.
You should be afraid of flashing the bios.
Wrong. Knowledge is power, which you appear to be short on.
If there is a valid reason to do it, you should prepare first.
Of course, just as you should prepare first for eating a mean, going to bed,
taking a shower, installing a program, or flashing a BIOS. It's simply
something not done very often becasue it's not needed very often, but it's
nothing to fear.
If you don't have one, purchase an uninterruptible power supply (about
$75-80 for an inexpensive one) as you should have a very dependable
power supply and landline power isn't that dependable. If power
fails during the minute or so that the flash requires, the computer
will not work again without replacing the chip that you were flashing.
Flashing a BIOS chip is so fast and reliable that this, as good and useful
as a UPS is, just isn't necessary. If one is paranoid about it, then don't
do it on stormy days or when traffic is heavy. If your ac power is normally
reliable, there is no reason for it not to be reliable for the few seconds
it takes to flash a BIOS.
Even if you are one of the one in many millions that has a power glitch
longer than the hold-over time of your PSU, it's still possible to flash the
BIOS and get going again; it IS an inconvenience, but ... highly unlikely.
A UPS is valuable and useful but don't buy one just to flash BIOS unless
you have lots of money to spend, in which case you probably already have
one.
Next, create the boot floppy disk as directed and then follow the
directions given by Dell. Flashes can be successfully performed and
I have done so on many Dell machines (I personally own an older 8100
model.) Normally goes without problems IF you have a good power
supply but with Murphy's law (that which can go wrong will) without
the good power supply power will fail at exactly the wrong time.
I'll bet I've flashed a lot more machines than you have and even in this
unreliable, totally above ground rural power grid, there has never been an
interruption occur during the flashing. You're fear-mongering without good
cause here. To mentione these things as a good thing to have and why is one
thing but to initmate that they are a MUST is just plain silly.
Your presentation leaves a LOT to be desired.
At least you were right about the non-progressive flashing need.
