 Webbrick and Monet are high performance workstations/servers based on the
 EV6 CPU and the Tsunami chipset. Tsunami is also used in much higher-end 
 systems and as such has plenty of performance to offer. DS10, VS10 and XP900

 Webbrick is shipped in a desktop-style case similar to the older 21164

 Memory:
 DS10 has 4 DIMM slots. DIMMs are installed as pairs. Please note that 
 DIMM pairs are not installed in adjacent DIMM sockets but rather physically
 interleaved. DIMM sizes of 32, 64, 128, 256 and 512 Mbytes are supported.
 
+When 2 pairs of identical-sized DIMMs are installed DS10 will use memory 
+interleaving for higher performance. DS10L, which has only 2 DIMM slots cannot 
+do interleaving.

 EIDE:
 The base model comes with a FUJITSU 9.5GB ATA disk as its boot device.
