bIOS Upgrade vs overlay

Please explain why a bios upgrade is preferable to an overlay if that is true. I've heard an overlay is unstable as one uses the disk more and more? Is that true? Why?

Is it better (pricewise or ease of performing the task) to download a bios upgrade or contacting the manufacturer of one's bios chip to see if they have an upgrade replacement chip?

My guess is, when you write and rewrite, which erases in the course of writing, one might erase some formatting, thus making that part of the disk non writeable. But the format recognized by a bios only has to be formatted once and one does not have to simulate a  bios in addition to a format, in order to see the whole hard drive and the information. Please correct anything I am saying, as it is only a guess!

Short and simple answer:  BIOS upgrade lets the computer see the HD 'as is'. An overlay 'lies' to the BIOS so the computer can see the HD and use it. Since it is a program that lives on the HD, it can get funky for a number of reasons, and can be a real pain to fix.

MArv100, basically as coral47 puts it the bios is the best way.  It is more stable than the other.  And does not take any resources from your system.  However running an overlay software it has to front end the drive and takes a slight bit overhead in translation.

Plus in general and most cases a HARDWARE solution is going to be much better than a SOFTWARE solution....Again software is translating or changing something....Hardware is generally provided.  

Some problems you may face later on if you do use the drive overlay software, is one....Booting to a floppy disk before enabling the drive overlay.....Installing OS's on a Drive that has overlay on it can overwrite the Overlay, or may not support the overlay software, if you plan to use more drives in the future and you need to have Overlay software for the drives, you would most likely have to buy the same manufacture drives so that the overlay software will support the drives.  

Here is a good site explaing some information on DDO(dynamic drive overlay) or Overlay software:
