HP 3300 Pro upgrade BIOS problem

[MassiAVM]

Hi, I have a HP Pro 3300 SSF with 7.11 BIOS and Windows 7 64it. I'd like to uprgrade to 8.06 or 813 version but I can't. I tried under Windows and command prompt but I have always error. Please someone had any experience?

Thank you

The 8.xx bios are 8mb in size and the 7.xx are only 4mb.  

If your system has the 8mb bios chip then the 8.06 or 8.13 can be installed.  I do not know of any app that can measure the size of the bios chip.

Maybe a magnifier assuming a code is even printed on the chip.  HWinfo64 was not capable, tried it on my pro 3400.

Discussion here where author soldered an 8mb chip onto the motherboard

I do not recommend that unless you have a de-soldering station and have some expertise in surface mounted components in addition to the programming tool needed.

The best you can do is the  7.16A bios.

I assume you have the cupertino-2 motherboard.  The bios is here

It will not give you UEFI (gtx-1060 etc) capability.  I assume you want to use the newer UEFI video cards and have a 500w or better power supply.   If you want the UEFI capability then you need a mod'ed 7.16 bios which is mentioned here

you will have to join the forum and in addition you will need a patched safuwin.exe app

There is a link to it somewhere. in the above thread.

To the best of my knowledge the 3300, 3400 and 3500 use the cupertino motherboard and except for the size of the bios chip they all use (or could use) the same bios.
