If your computer is working fine,
it is not necessary to update BIOS even if there is a latest version available.
Update BIOS at your own Risk
If you decide to update your BIOS all the way to A14, you must...
Go in steps. Skip A11 & A13, these are known to have issues.
Before updating BIOS, please ensure that:
*The computer has power source connected.
*No external devices (flash drives, printers, external hard drives) should be connected.
*All other programs should be closed and documents saved.
First update the BIOS from A01 to A02, then A03
Then from A03 to A06
Dell has posted here that it's o.k. to go A12 next.
I'm using BIOS A14 on my Andromeda R1.
