Boot error migrating to R720

[itlists]

Hi all,

 

I've been running unRAID 5.11.5 on homebrew server for a few years. Been meaning to migrate to a R720 I bought last year.

Last night something malfunctioned on the server (possibly motherboard or HBA card?). So now I'm forced to move to the R720.

 

This R720 has a built-in H710 mini which I've successfully flashed to IT mode following the instructions here: https://fohdeesha.com/docs/perc.html

 

I've inserted the unRAID USB drive into the internal onboard USB slot and attempted to boot, without any drives connected.

I'm getting an error message regardless of whether unRAID OS or unRAID OS GUI mode is selected:

Failed to allocated memory for kernel command line, bailing out
Booting kernel failed: Bad file number

(screenshot attached)

 

Very grateful for any help please. Server is offline so we can't access any of our files, data, etc.

 

Thanks kindly!

Troubleshooting suggestion:  Since all drives not yet connected, try building a trial version on a new flash drive, and see if that will at least boot up.  Will then see if it is something with the new hardware or your current flash drive (drive or configuration).
