Is there a known problem if I do update? Thanks

There is always a chance that a BIOS update can brick a system. So I don't know what you are asking.

You'll get A05 here. No there's no problems with A05, it's quite an old update which is why it's fallen off the list of "previous versions"

Hi,  Thanks  for your reply.  I understand the possibility of failure to update a BIOS.  I guess the primary question is - why does DELL's update list show 0990-A09 update  for my Optiplex 990 but doesn't have 0990-A05 which is required before 0990-A09 will continue?  The second part is the Q re known update problems; if there is no response to this and I can get a  copy of 0990-A05 then the risk is mine  :-)

Hi,  Thank you. I have d/loaded A-05 , will wait a while to see if anyone has had a problem before I proceed with A05.  All being well with that I'll then try A-09.   If that succeeds (or not) I'll post the results here.

***** Well all succeeded A05 first, then A09 after a short time and a couple of restarts (by me) so many thanks to the willing members of this support forum.
