This has to be the most common FAQ for this group. You have non-Intel
flash chips on your new SIMMs and boot ROMs that are too old to know about
the different access method for the flash chips you have.
You need to either get the (free, call TAC) BOOT-2500= ROM upgrade from
Cisco, or exchange the flash SIMMs for ones using Intel chips. Note that
Intel no longer makes those chips, which is why everybody has this prob-
lem.
