Hogwash!  While I'm not a complete fan of the Cisco boot process (in
particular, the apparent redundancy of much of the bootstrap process),
it takes nothing like 30 minutes to load a fully loaded box.  A number
of our 7513's are populated with only VIP2-40s (in all 11 slots), and
take on the order or ~5 minutes to load.  The most time-intensive
operation is decompressing the images (which themselves are getting a
bit silly in size, especially the -boot images).

Downloading microcode to VIP2 processors takes relatively little time.
