[nsp] Booting an MSFC from sup-slot0:

[Brian]

I am working on a 6509 with dual Sup1A's and MSFC's.  I am running into  
some problems.
I am trying to have the MSFC boot the bootldr image from bootflash:,  
but have the regular
IOS image come from sup-slot0:.

I am using Hybrid configuration, CatOS 6.3(7) and MSFC 12.1.13E6.

I can boot the regular IOS image from bootflash:, but not from slot0:

boot system flash sup-slot0: c6msfc-jsv-mz.121-13.E6
boot system flash bootflash: c6msfc-jsv-mz.121-13.E6
boot bootldr bootflash:c6msfc-boot-mz.121-13.E6

Is how I have it configured, this way, after sup-slot0: fails, I am  
able to at
least have my IOS.

Some things I have tried and checked:

1. configuration register is 0x2102
2. having just one "boot system flash" line, that points to sup-slot0:,  
and no boot line
      for bootflash:, still has the same effect.
3. Just as shown above, the boot line for bootflash: comes 2nd.
4. I tried to "boot sup-slot0: c6msfc-jsv-mz.121-13.E6" from rommon>,  
this does not work.
5. The IOS checksum / filesize, is correct.
6. Both Sup1A's/MSFC's exhibit the same behavior.
7. while on the MSFC, I can copy succesfully from sup-slot0: to  
bootflash:
8. The flashcards in sup-slot0: are Cisco originals, freshly formatted  
on the actual
      6509 Sup's I am working on.

I was wondering if anyone had any ideas as to what could be my problem.  
  I read about a take issue with
regards to booting off of sup-slot0: (CSCdr35304) but that bug was long  
ago fixed and should not be impacting me.

I used the format "boot system flash sup-slot0:<image name>" because  
thats what I found in the Cat6500 Configuration Guide at  
http://www.cisco.com/en/US/products/hw/switches/ps708/ 
products_configuration_guide_chapter09186a008007f29d.html

However, now doing some more searching, I find a conflicting document  
on cisco.com that says to use "boot sup-slot0: system_image", that link  
is:
http://www.cisco.com/en/US/partner/products/hw/switches/ps708/ 
products_configuration_guide_chapter09186a00800ebac2.html

Could it be that "boot sup-slot0:<image_name>" is really the correct  
format, and that is why it wasn't working for me all along?  There are  
multiple documents on cisco that show both formats.

I appreciate any help anyone can give me.
