Yes, you may always update the system to the latest version available in the support website. However I would like to know the reason for the BOIS update. Because if the system is working fine, it is not necessary to update BIOS even if there is a latest version available.
Thanks for getting back with your reply.
The reason for contemplating the BIOS upgrade is that I have been considering replacing the hd with an ssd and was really wondering if my current BIOS would be capable of handling that.
BTW, was mistaken re. bios version. I have A05 not A06 as previously stated.
