No, dcdbas has nothing to do with this. I'll have to submit a patch
against the docs. The program you need to use already exists and is
open source. You can use libsmbios to do this.
http://linux.dell.com/libsmbios/main.
The binary you want to use is "activateCmosToken", under bins/output/
(after compilation). The command line syntax is like this:
activateCmosToken 0x005C
If you want to cancel a BIOS update that has already been activated
(per above), use:
activateCmosToken 0x005D
Basically, follow the docs in the RBU docs as far as cat-ing the bios
update image to the rbu sysfs files, then use the activateCmosToken
program to tell BIOS to do the update on reboot.
