=======================================================================
HBIOS Loading Modes:
  ROMBOOT: Startup from ROM Bank BID_BOOT
  APPBOOT: Startup as CP/M application
  IMGBOOT: Startup from RAM Bank BID_USR
=======================================================================

 - If not (APPBOOT), include page 0

 - Base Hardware Init
   - Iff (ROMBOOT), init BBR

 - Install Proxy
   - Set CURBNK:
     - If ROMBOOT, then BID_BOOT, else BID_USR

 - Install HBIOS
   - Copy from CURBNK:0 --> BID_BIOS:0 ($8000 bytes)

 - Transition to HBIOS in BID_BIOS

 - Copy OS Image to USR Bank
   - If (ROM_MODE), copy BID_OS:0 --> BID_USR:0
   - Else, copy BID_USR:<os image start> --> BID_USR:0

 - Chain to BID_USR:0
