There is still enterprise software that it is not feasible to move to something else.
As well, certain mainframes will only boot from OS/2... the service console, a PC, is what boots a mainframe.
It literally uses a parallel printer connection to a port on the mainframe to load the microcode and the 'nucleus' of the mainframe into the memory.
Once this is done the CPU is in an initial known condition and can boot up.
