Looking over a senior guys notes and attempting to help out. We have 6509 upon reboot boots to RMON. From rmon we can boot no problem, but then if its rebooted, back to rmon.
The config looked correct, but am trying to help, here is the relevant parts, if more needed, please let me know.
RTR-01#sh bootvar
BOOT variable = sup-bootflash:c6sup22-psv-mz.121-27b.E3.bin,1
CONFIG_FILE variable = bootflash:startup-config
BOOTLDR variable =
Configuration register is 0x2102
RTR-01#sh ver | inc reg
Configuration register is 0x2102
RTR-01#sh run | inc boot
boot system flash sup-bootflash:c6sup22-psv-mz.121-27b.E3.bin
boot config bootflash:startup-config

I left some non-relevant dir out of the above dir output.
I searched Ciscos site but am unable to discover why this is happening. Any input would be appreciated.
Thanks!

Its actully at 6506 if that matters.
cisco WS-C6506 (R7000) processor (revision 2.0) with 227328K/34816K bytes of memory.
The only idea I have gathered from reading other post is its set to autoboot:
At rommon prompt, type confreg….
Say no until you get to the bottom question…
At “ change the boot characteristics": answer yes…
Enter 2 to boot system as autoboot
Type "reset"
Any other ideas?

Hi Jimmy,
Never played with a Sup 2 before so if it's OK with you, I'll take a "stab in the dark".
Can you post the bootup process? I would like to see when the supervisor card goes into ROMmon.

This I can not do as its my ticket at work. I was just trying to learn something along the way. Plus its a LAN rtr, so if I rebooted it alarms would go off everywhere......maybe the site is going to have a 'power' issue soon lol. Oh wait, dual power supplies, one going to a UPS and other to house power, dual power failure! So unfortunately I can not get a screen shot, I did email the assigned tech to see if its available.

Thanks Jimmy. Looking forward to see the result of the *cough* power outage *cough*.
PS: Make sure no one "trips" over the power cables, ok? Take it from me, an expert in "tripping over" power cables in a data centre to the point that I've been banned. LOL!

Like Leo said, looking at the bootup process will be interesting. That might give us insight on which processor forced the ROMmon. Could you also post the complete show version output please?
Since you can boot the image correctly from ROMmon, that rules out a possible memory corruption issue or a corrupted image. This could be a case of mismatched config registers between the RP and the SP. Could you login to the SP and check what the config register has been set to?

try this
6500# remote command switch show boot
BOOT variable = sup-bootdisk:
Configuration register is 0x2102
If configuration Register is not 0X2102 then execute command,
6500# confg t
6500(config)# config-register 0x2102
6500(config)#end
6500#write mem
6500#reload
Verify after reload:
6500#show bootvar
6500#Show Version
6500# remote command switch show boot
