HP Pro 3400 MT refuses to do a BIOS Update in Windows.

[misraa]

I tried to a BIOS update to try to solve some POST issues but upon trying to do, it says "Proper command line parameters were not passed. No actions taken." I'm sure the HP Program is just broken and I did find one from AMI that I'll try. Any solutions to hopefully make the HP Program work properly?

You probably do not have the correct bios.

Look at the motherboard.  is it a Foxconn ?

if so, is it cupertino 2?

use the cupertino2 bios below, but read this first

Some HP motherboard made by Pegatron and Foxconn have bios MODs to use newer graphic cards.
