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.
