Help getting an "old" 1801 back on track

[giulio-leone-71]

Ciao,

I've been trying to give a new life to an 1801 router for a few days now. I replaced the RAM and the Compact Flash card, after having tested it on another device. The router boots, but only in ROMMON mode.
I'm currently getting this message: %SMC-2-BAD_ID_HW: Failed Identification Test in 0/-1/-1
I think it's a cookie configuration problem but unfortunately after several hours of searching, I haven't been able to find any indication of the (precise) cookie data structure so that I can re-enter them.
If someone can give me a better idea, I'd be grateful.

You say that you tested RAM and compact flash on another device. What kind of device was it? I am wondering if there is now a valid image for the router to boot.

It would be helpful if you would boot the router again, copy and post all of the messages generated in the boot process.
