BIOS upgrade fails Optiples 990

 I bought used Optiplex 990D, now running happily with Windows 10 on new SSD.  Current BIOS is A07. New BIOS's available to provide security for CPU are A20 & A23.  Error messages stating that neither will install unless I 1st install A10.  However, A10 isn't available on Dell website.  What do I do?

Re: BIOS upgrade fails Optiples 990

A10 is still available.  On the BIOS listing, click on "Older Versions" and you can access A10.

FWIW, Dell does not officially support Win 10 on this model.  Win 10 may work OK but there is no Dell support for it.
