Update PE R200 bios running CentOS 7

I've tried two different methods for updating the BIOS to the latest v1.4.3 (currently on 1.0.0) on this R200 server running the latest CentOS 7 x86_64.

First attempt was this method, but after running update_firmware it just gives the error "Did not find a newer package to install that meets all installation checks."

Since there is indeed newer BIOS maybe the update is just failing on CentOS 7 because it isn't sure what that OS is yet?

Ok well how about we download the .BIN and run it directly from here

It appears to want a lot of 32 bit libraries, ok so I install glibc.i686 and compat-libstdc++.i686 to get past a few errors. However then it errors on libxml2, unfortunately it wants libxml2.i686 but CentOS 7 gives a strong warning to not install that library:

yum install libxml2.i686

"Error:  Multilib version problems found. This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. "

So I guess the question is, without physical access to this server what method can I use to update the BIOS? Thanks!
