[c-nsp] 6500/7600 boot issues

[Jon Lewis]

Several months ago, I posted about a 6509/sup7203bxl we have that won't 
boot properly without manual help (being told to boot from the rom-mon 
prompt, or fails-back to booting from sup-bootflash...depending on what 
rom-mon code we use (upgraded to latest falls back to whatever is in 
sup-bootflash, gold just sits at rom-mon waiting for an operator to tell 
it to boot)).  I just noticed something I suspect may be the issue, but 
I'm not sure how it happened or how to change it.

The config-register on the supervisor (as shown by rem com sw sh ver) is 
0x2142.  On all our other 6500s, both the msfc and sup conf-regs are 
0x2102.  How do you change the conf-reg on the supervisor?  Is it as 
simple as
rem com sw conf t
conf-reg 0x2102
exit
reload

I'm a little hesitant to try this on a running router.
