R720 Bricked Bios Help

BIOS/UEFI Modding BIOS Modding Guides and Problems

Hi,

I have a dell R720 that I bought but the bios seems to be corrupted. I have tried almost all the options in order to attempt to fix and troubleshoot it hut have had no luck. I have working IDRAC but no vga or virtual console. Idrac shows the post code 0x7f after a couple of minutes although I suspect this is an error as it does not have any os installed.

I have bought a bios flasher clamp but I do not know how to locate the bios chip or how to use the clamp to repair the bios. Can anyone help me?

Thank you

EDIT:

Are you sure that across those threads and posts there’s not a single info or foto with SPI location…

Those posts do not have the same issue

Hello @LeCodyMan ,

Are you using the onboard VGA connector?

Have you tried using a VIdeo Card?

5

Using a video card doesn’t work

6

Anything over the serial port?

There should be messages during the boot process.

7

How many CPUs are installed?

8

2 cpus, haven’t checked the serial port. I am thinking I need to swap in an older cpu to update the bios

9

Using a E5 -V2 ?

Are you able to flash from the iDRAC web interface?

No as for that you need to be able to boot into the lifecycle controller
