DEC bootstrap ROMs for the PDP-11s, from the M9301 ROM on, allowed use of a symbolic device name to specify a device to boot from, when using the console emulator function.

These codes included (not all were supported by all ROMs):

DD DL11 TU58 Casette magnetic tape
DK RK11 RK02-RK03/RK05 Removable cartridge disk
DL RL11 RL01/RL02 Removable cartridge disk
DM RK611 RK06/RK07 Removable cartridge disk
DP RP11 RP02/RP03 Removable cartridge disk
DS RH11/RH70 RS03/RS04 Fixed-head disk
DT TC11 TU55/TU56 DECtape magnetic tape
