  You're confusing the 730 with the 750.  On a 730 you didn't have any choice, assuming you're starting from power off.  The CPU microcode, CFE software, VMB, and pretty much everything else was stored on the TU58. 

  The 750 was a different matter.  The microcode was in ROM, VMB was in the boot block on the disk, and you could live without the TU58.
