/* Step 2 */
* Unexpanded CPC 464 without CPC 6128 OS/BASIC ROM installed, having only both DDI-1 3" & 3.5" external disc drives connected.
<BR>
To do that, you must remove six two screws first, open the cover, carefully remove the [[AMSDOS]] ROM chip with "AMSTRAD 40009" printed on top of it and replace it with [[ParaDOS]] ROM. Then put the cover back on, and put the six two screws back on. <BR>

* 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 in [[Expanding_from_CPC_464_to_CPC_6128_Spec#Step_3|step 3]]).
