Hello,
I am more the kind of "do it yourself" type when it comes to
computers
Flashing the (presumably) dead BIOS chip myself seems interesting.
So far I have learned of two options:
1. Hot swapping the bios. (weir/unreliable and dangerous)
2. Use an external device.
******************
*** Option 1 ***:
******************
I read about "hot swapping" the bios, but that seems way to dangerous.
And it's also weird I don't understand it, to help me understand it a
little bit I need a history lesson and more :
Were interrupts handled by CPU or BIOS back in the old days ?
Nowadays some say the BIOS is loaded into RAM (shadowed), does that
mean the CPU actually executes the BIOS code ?
Some say hot swapping works because of just that ! Since the BIOS is
in RAM, the bios chip can be removed while the computer is ON !
And it will even continue functioning ?!?
Amazing... I never tried it... especially not with my motherboard...
anybody tried it ?
Is it really true ??? How can that be ??? Does the CPU execute the
bios code ???
Maybe the BIOS code is just like another piece of software/program/DLL
library that gets sorta linked to programs... how all this works ???
hmm kinda strange...
Whatever the case may be, it's not recommended by others and I can
sure understand why
So that leads to option 2
******************
*** Option 2 ***:
******************
Use a device.
For that I have following questions:
What kind of chip is it ?
What kind of devices are available ?
How much do these devices cost ?
What's the cheapest device ?
How much does such a bios chip cost ?
Where can I order one ?
Thanks for any answers.
I am totaly newb to this any help and/or info is greatly appreciated
