Hi,
i found it's a bit confusing on these wording found at C6500 chassis.
Question 1
What is these term, and how really what diffrentiate between.
(a) bootflash:
(b) disk0:
(c) sup-bootdisk:
(d) sup-bootflash:
Question 2
when i type show sup-bootdisk and show sup-bootflash, both show that having the identical image file and attribute. It make no different on this? Are they actually the same thing?
Question 3
For the 6500 booting process, is it using either bootflash:, sup-bootflash: or sup-bootdisk: to load and boot a Cisco IOS Software image.
the command for statically configure boot variable is "boot system flash sup-bootdisk:image-name"
Thanks
Noel

The Catalyst 6500 supervisor engines has:
1) internal flash memory devices:
2) external flash memory devices as CompactFlash slots:
Please look at the following documents:
What about sup-bootdisk?
Initially, Sup720 has switch processor (SP) 64-MB internal flash memory in the form of memory module (DIMM). In this case, SP flash is referred to as sup-bootflash.
Subsequently, Sup720 has switch processor (SP) 512-MB internal flash memory in the form of CompactFlash in the CompactFlash Adapter inserted in the DIMM socket. In this case, SP flash is referred to as sup-bootdisk.
IOS historically supports both name for switch processor (SP) flash - sup-bootflash & sup-bootdisk for Sup720, Sup720-10GE...
Bootable images are stored in sup-bootflash/sup-bootdisk for the Sup720, Sup720-10GE and bootdisk for Sup2T...

With the SUP2T there's just one onboard flash, called "bootdisk", but you can use "bootflash:" in the config to alias to it.
There's a couple more links in this thread, if you're still curious.
