Nspire B800 Bios

Hi, I have an old Nspire B800 laptop that i want to make use of for a little project, I know its a bit draconian but is there a chance you can tell me how to get the most up to date bios for it please.

The bios on it is 207, and its an A15YA is there an update to this?

Now sorted, thanks Coops
