Booting IOS Image from PCMCIA flash on Catalyst 6500 in Native Mode

I have a couple 6500 switches (Sup 720/MSFC 3) to upgrade. They are currently running IP Base, but I'd like to run Advanced Enterprise in order to use the full Firewall features.

Since the images are over 70 MB, I will need to boot from the PCMCIA flash cards (disk0 and disk1). The problem is, when trying to boot from those devices, I get "bad magic number" (wasn't able to capure the exact output, sorry). I tried "boot disk0:" and "boot bootflash:" with the same problems. Finally, did a "boot sup-bootflash:" and it loaded my old image. It appeared as if the bootstrap wasn't recognizing any filesystem other than sup-bootflash.

In know in Mixed mode, you must first boot a small boot image for the MSFC, then IOS, i.e.:

boot bootldr bootflash:

boot system flash disk0:

How should the boot from disk0 be handled in Native IOS?


Re: Booting IOS Image from PCMCIA flash on Catalyst 6500 in Nati


In native IOS you just need to specify the boot system.

boot system flash disk0:blahblahblah.SX4.bin
