I have got some strange experience when I install the C6509.

I configured the boorvar like following.

boot system flash sup-bootdisk: *.bin

boot system flash disk0: *.bin

* means the IOS name, I'm not typed like * :)

If I configured above, The first boot is sup-bootdisk and next is disk0. So I wrote to nvram. before re-booting the bootvar indicated as first is sup-bootdisk and next is disk0:

After checking the bootvar and I tried to reload the chassis.

After finishing the booting, I check up the bootvar, but I can't understand the bootvar.

Definitly, I saved the nvram. However the bootvar is indicated disk0:, and then sup-bootdisk. the configuration saved before reload didn't saved to nvram.

the configuration register is 0x2102 :)

Anyone thought about this?
