Appendix C Disk-On-Chip
The Raptor AT offers two on-board flash disks as optional devices. The
Disk-On-Chip is a single chip flash disk device in a standard 32-pin
DIP socket.
It features up to 288MB (each) of storage capacity with high-speed
boot-up capabilities, including the Flash File System (FFS) for easy
storage.
This feature of the Raptor AT is a perfect replacement for conventional
hard-drives in the harsh industrial environment where shock and
vibration is a burden for standard hard drives.
Jumper JP7 selects the memory addresses to be used for the Disk-On-
Chip. Possible addresses are listed below.
