Here is one procedure that works: • Put the single-density LDOS master disk in drive 0. • Put a blank disk in drive 1. • Boot. • Type FDUBL (TANDY) or FDUBL (PERCOM), depending on whether you have a Tandy or non-Tandy double density adaptor. If you are doing this procedure on an emulator rather than a real machine, check which type of adaptor it is emulating. • Type FORMAT :1 (SYSTEM) • Answer the questions that FORMAT asks. • Type SOLE :1 • Type BACKUP :0 :1 (SYS,INV) • Type SYSTEM (DRIVE=1,SYSGEN) The disk in drive 1 is now a bootable, double-density LDOS system disk. Test it as follows: • Remove the LDOS master disk from drive 0. • Move the new disk from drive 1 to drive 0. • Boot. At this point you may want to put the remaining LDOS files from the LDOSXTRA disk onto your new boot disk: • Insert the LDOSXTRA disk in drive 1.
