HELPTX:ASCIZ \WTBOOT WILL ASK THE QUESTIONS "SELECT UNITS?"
IF THE ANSWER IS YES, WTBOOT WILL ASK YOU WHICH TYPE OF BOOTS TO
WRITE ON EACH UNIT IN THE SYSTEM BY TYPING "UNIT" FOLLOWED BY THE
UNIT NAME (NOTE THAT "RP0X" MEANS RP04, RP05, OR RP06). RESPOND WITH
"DP" IF YOU WANT WTBOOT TO WRITE RP02/RP03 BOOTS ON THE
PACK MOUNTED ON THAT UNIT
"RP" IF YOU WANT WTBOOT TO WRITE RH10/RP0X BOOTS ON THE PACK
MOUNTED ON THAT UNIT
\
IFN FTKL10,<
HELPT2:ASCIZ \ "R2" IF YOU WANT WTBOOT TO WRITE RH20/RP0X BOOTS ON THE PACK
MOUNTED ON THAT UNIT
\
>
HELPT3:ASCIZ \ "ZERO" IF YOU WANT THE MONITOR NEVER TO READ BOOTS FROM THAT
PACK
"SKIP" IF YOU DON'T WANT WTBOOT TO CHANGE THAT PACK
OR CARRIAGE RETURN IF YOU WANT WTBOOT TO WRITE THE DEFAULT BOOTS

WHICH ARE ON RH10'S, RH20/RP0X BOOTS ON PACKS WHICH ARE ON RH20'S).
\
>
HELPT5:ASCIZ \FOR EACH RS04 OR RP0X, WTBOOT WILL ASK IF THE READIN LOADER SHOULD
BE WRITTEN IN 18 OR 22 BIT MODE FORMAT. RESPOND WITH
"NONE" IF NO READIN LOADER SHOULD BE WRITTEN ON BLOCK 0 (KL10)
"18" IF THE UNIT IS NOT ON A CONTROLLER CONNECTED TO A DF10C,
OR IF THE DF10C IS NORMALLY IN 18 BIT MODE.
"22" IF THE DF10C IS NORMALLY IN 22 BIT MODE
OR CARRIAGE RETURN FOR THE DEFAULT (18 BIT ON EVEN UNITS, 22 ON ODD).
IF THE ANSWER TO "SELECT UNITS" IS NO, WTBOOT WILL WRITE THE
DEFAULT BOOTS ON ALL PACKS. IF WTBOOT IS BEING RUN ON A KL10
IT WILL NOT WRITE READIN LOADERS, IF NOT BEING RUN ON A KL10
WTBOOT WILL WRITE THE DEFAULT READIN LOADER ON ALL RS04'S AND RP0X'S.
