[nsp] 7507 flash

[HyunSeog Ryu]

I don't think you can combine two flash memory for large IOS image.
That's why Cisco took some features from new IOS to digest IOS size.
If flash disk is working on your platform, you can use flash disk, so called ATA
flash disk.
I see some benefit from ATA-flash-disk because you don't need to squeeze to free
deleted file space, but not cleaned from raw format itself.
But there might be compatability issue with platform.

So I usually use flash memory as primary boot device, and flash disk as a backup
storage. 

Especially if you use RSP2, I don't want to try IOS image larger than flash
memory.
Of course, you can use 32 MB flash memory, which is MEM-RSP-FLC32M Cisco part
number. 

I used SanDisk 128MB ATA flash disk with RSP4, and I don't see the problem so
far.
But it will be on your own risk for that. 
Cisco started to list flash disk options from RSP8 model.
