bios updating, flashing, reverting to old

this is really confusing me
first of all. how can I get my original bios? i want to save it to a cd, floppy, or whereever. because i've read around and saw that people were having problems with an asus bios update, and they couldnt revert to old bios
how can I get my original bios?(current bios has never been updated, but the PC is inaccessible, since its broken)

(on flashing, updating, boot floppy etc.. ez flash, a flash)
which does what, and which is better.. my manual isnt very clear on it, and so is the website :|

The Aflash bios updater will automatically save the old bios to the floppy when you are updating the bios. However, the computer must be working to do that. You said it is broken. What are the symptoms. Maybe we can help.
