BIOS 2.4.3 was released to the web page last week.
Not all of my machines run OMSA, so for some I use the stand-alone update packages. I have noticed that the BIOS update to 2.3.0 was installed on the R720xds running OMSA, but the Dell web page only has 2.2.3 listed, so where's the update package for 2.3.0?
R720xd: Where's the BIOS 2.3.0 update?
