* A. Replace the [[AMSDOS]] / CP/M bootstrap ROM with [[ParaDOS]] ROM inside the disc interface (it allows you to use the full capacity on 3.5" disc drive).

* [[464Plus_Conversion#Jonathanen.27s_Easy_Way_To_464.2B_Conversion|Upgraded CPC 464+ to 6128+ spec]] <BR>
* Unexpanded CPC 464 without CPC 6128 OS/BASIC ROM installed with , having only both DDI-1 3" & 3.5" external disc drives connected only.

* B. Leave the [[AMSDOS]] / CPM bootstrap ROM inside the [[Media:Gerald_DDI-1_MF0004B.jpg|disc interface]] (if you want to use DR. LOGO 2 & 3 on upgraded CPC 464) and put [[ParaDOS]] ROM inside the [[Rombo_Rombox|Rombo ROMBOX]] with other ROMS (as shown belowin step 3).
