i'm currently stuck right now... i have a 6506 with a sup1a-2ge running in hybrid mode. i need to run one of the cryptographic ios images with ssh/3des, but the 16mb i have for bootflash on the router isn't enough for both the image and bootldr. if i were to migrate to native mode, does that buy me the ability to boot off of my pcmcia slot? if not, any other suggestions (other than disable telnet & access the router via sess 15!!!)?
another question on image files if you can help...
are the c6msfc-xxxxxxxx images for the ios running in hybrid mode and the c6sup11-xxxxxx images for running in native on a sup1/msfc1? i'm a little confused...
thanks in advance, eric

Hi,
As per your cincenr, there is no need to convert Hybrid to native just to get the ability to boot your sup from slot0:. That you can do from Hybrid mode also.
as far as bootflash upgrade on MSFC2 is concerned , you can do that. You can upgrade it from 16 to 32mb, here is how you can do this :

Still if you want to boot from from slot0:, here is theprocedure to do that, this doc will also provide you overview on naming conventions of Cisco IOS and CatOS of 6500 :

Aashish,
Thanks for the reply. Unfortunately the IOS in hybrid mode can't use slot0: other than to copy images from it (at least with a Sup1A-2GE / msfc (not msfc2)) - you can't actually boot from it. I would consider upgrading the bootflash, but as far I can tell Cisco doesn't have an upgrade kit for the Sup1A-2GE, only for the msfc2 model which takes a different kind of memory.
The 2nd link you gave me refers to utilizing slot0: from a native mode ios image (not from a c6msfc image), which is a promising solution, just not one I can accomplish this week.
Thanks,
Eric

Is this a restriction on the Sup1? I know we do it on on msfc2's. Just modify the boot statement to boot system flash sup-slot0:imagename . Cisco did have some problems with the code to get this to work right so i would investigate the bugs on bugtracker just in case you run into this but we run the bootloader on msfc bootflash and the image in slot0: .

There is no memory upgrade options for MSFC1. You have 2 options
1)You can boot off slot0: even with hybrid OS. When running hybrid, the MSFC cannot read the contents of the slot0: but still can boot from it. For this to work you need to have a boot loader image in the MSFC bootflash. Point your bootvariable to slot0:
"boot system flash sup-slot0:c6msfc-xxxxxxxx.bin"
2)The newer IOS(12.1(19)E) and later do not need a boot ldr image. So if you have enough space for the normal IOS file, you can just copy it to the MSFC bootflash and you will be fine.
Personally, I would go with option 2.
For your other question, yes you are correct. c6msfc-xxxxxxxx images are hybrid MSFC images and the c6sup11-xxxxxx images are native IOS images.
