I tried to update the BIOS from my HP DL160G6's. Unfortunately the Windows update degraded my BIOS version from 243 to 237. But when I try to upgrade both servers to version the update fails.

First I got a warning like:

CMOS Layout difference between System ROM and ROM file has detected.
AFU recommand (sic) adding /C commands of your original input commands.

Press "A" to accept AFU's recommendation. 
Press "F" to keep original input commands.

And the update did not do anything.

But now I get a message like:

Reading flash ........ done
Bootblock checksum ... ok
Module checksums ..... bad
Error: BIOS checksum error

And the update stops.

I tried some commands form this page: http://www.ami.com/support/downloads/txt/AFU_README.TXT But I don't try to much, the servers are still booting.

Does anyone know how to update my servers to BIOS version 245?

I used this version http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3884344&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D%257CswItem%253DMTX_7bd12651ab954fdcb0d7ee164a%257CswEnvOID%253D54%257CitemLocale%253D%257CswLang%253D%257Cmode%253D%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken and created a bootable USB stick sith HPQUSB.exe
