[j-nsp] M7i stuck in PXE boot loop

[Tom Storey]

Hi everyone. I powered off an M7i yesterday to relocate it to a new
rack, and after powering back on it seems to have forgotten it has a
CF and HDD or even a PCMCIA slot, and is only attempting to boot from
ethernet.

e.g.

Will try to boot from :
Ethernet
Boot Sequence is reseted due to a PowerUp

and so on.

Tried a reseat of the RE, reseated the CF, reset, power on/off the
whole chassis. Nothing seems to be working.

Has anyone come across this before and knows how to fix it, other than
replacing the RE?

I had a similar issue with it once before, but at that stage it
actually booted to a version-ish of JunOS where I was able to
re-configure the bootlist to include the HDD and CF, this time its not
even getting that far. :-(

Cheers
