Dec850 Bios update 10a not bootable.

[grimelog]

I just downloaded the latest bios update. After dding it to a disk, from Arch Linux, it is not bootable on a Dec850. gparted keeps giving an error about not being able to have a partition outside of the disk. I saw a few posts saying that means there's space in the img that needs to be zeroed out. The partition has iba for the flag should I just add boot to that?

Just used a larger usb, and it copied find.
