Most recent BIOS update version for a z400

HP Recommended
Workstation z400
Microsoft Windows 10 (64-bit)

So my uncle just gave me a z400 as a basic computer to start and every time I install Windows 10 and run the updates it gets stuck after the Windows load screen comes up and just keeps trying to restart but doesn't even get to the main start screen for the computer (where I can access the BIOS). So after lots or research I found out I need to update my BIOS, I was just wondering what the newest version was for my BIOS?

The latest BIOS update can be found under the W7 driver section for your PC.  v3.61.


Since you are running W10, use the F10 system flash method to update the BIOS, because the Windows based flash was only written to work in W7.


F10 Setup BIOS Flashing

The HP Workstation system supported by this Softpaq provides a BIOS upgrade option through F10 setup using the “Flash System ROM” feature.  Reboot the PC and press F10 to enter setup.  In the File menu, select the “Flash System ROM” item.  This flash utility will present the user with the option to select the media containing the BIOS image file (XXX_MMmm.bin).  The binary image file is contained in the DOS Flash directory and is named XXX_MMmm.bin where "XXX" is the abbreviated BIOS family, "MM" is the major version number, and "mm" is the minor version number.  F10 ROM based flash can accept the binary file from the root directory of any removable media such as USB or CD. On the Z800, Z600, and Z400 platforms the floppy diskette is no longer supported as a BIOS flash device as the ROM image is too large to fit on the floppy disks.  The BIOS CD Media file, included in this Softpaq, should be used to create a BIOS image CD.  When flashing with F10 ROM based flash, the CD media must be El-Torito compatible.  The user is prompted when the process is completed.  The new BIOS code will not take effect until the PC is rebooted.
