1.A system configuration file is contained in NVRAM, which allows the software to control several system variables.

2.Only Intel Series 2 Flash memory cards can be used with the RSP7000.

System Software

The Cisco 7000 series routers support downloadable system software and microcode for most Cisco IOS and microcode upgrades, which enables you to remotely download, store, and boot from a new image. The publication Upgrading Software and Microcode in Cisco 7XXX Series Routers (Document Number 78-1144-xx), which accompanies all Cisco IOS upgrade kits, provides instructions for upgrading over the network or from floppy disks. Flash memory contains the default system software. An erasable programmable read-only memory (EPROM) device contains the latest microcode version, in compressed form, for each interface processor. At system startup, an internal system utility scans for compatibility problems between the installed interface processor types and the bundled microcode images, then decompresses the images into running dynamic random-access memory (DRAM). The bundled microcode images then function the same as the EPROM images.
