Sorry, but I don't understand what is the current status ?

Are you in rommon ?

Or normal prompt ?

Your nvram got most probably erased and therefore there is no config so ACE does not know which image to start probably.


Do a 'dir disk0:' from rommon.

If you can see an ACE image.

Do 'boot disk0:' and then after that a 'reset' still from romon.

If I am reading the question correctly, then I am having same issue with an ACE 10 in my lab. I cannot access the ACE through the session command, and when I physically console into the module itself I can't type anything.

-------------------------------------------------------------------------------------------------

ACE platform with 1048576 Kbytes of main memory

Autoboot: failed, boot string  not found
rommon 1 >

----------------------------------

When I am consoled into the ACE, nothing I type shows up. Not sure if it's a console setting, or what

Hi Josh,


The fact that you see anything on your console is a good sign.  This just means that the communication from your PC isn't getting to the ACE, but communication from the ACE is making it to your PC.  Here are the settings I use in the lab (using HyperTerminal):


9600 bits per second

8 Data bits

Parity: None

Stop Bits:  1

Flow Control:  Xon / Xoff


Hope that helps,


Sean

Thanks for suggesting that. I just got a new PC and just installed Secure CRT yesterday and hadn't thought of checking that. This ACE10 used to be running SBC code. Is there any issue with just changing it to A2(3.1)?

Hi Josh,


I'm not sure if there will be any issues changing to ACE code.  I wouldn't expect any problems since it is the same hardware platform.  Let us know how it goes.


I don't know what an SBC does, but I bet the hardware will be much happier with ACE software on it    (I hope)


Thanks,

Sean
