PowerEdge T100 BIOS won't update

Guys,

I have a T100 and I'm trying to update the BIOS so we can install RHEL 6 (Server 2003 currently) and I'm running into some issues where the BIOS won't update.

Currently installed 1.0.0

Just downloaded 1.4.1

When I try to install the update, I get an error thats attached.Image may be NSFW.
Clik here to view.

Can you guys advise how to resolve this?  RHEL will not install on this server without the BIOS being updated (as far as I know)

Thanks so much
