==== Notes ====
Finally, I have found a way of installing ParaDos [[ParaDOS]] ROM in my CPC 664, I tried to use Rombo Rom box & Super Power Rom Card, but both of them didn't work on my CPC 664, and I have a spare ParaDos [[ParaDOS]] ROM, I was planning to sell it on ebay, as no point of keeping ParaDos [[ParaDOS]] ROM only which I have no spare CPC series computers or DDI-1 drives with interfaces to install it on to.
Suddenly, as soon when I woke up with Amstrad CPC computers / accessories lying down on the floor, an idea just popped up in my mind, remembering how I remove the [[AMSDOS ]] ROM and replace it with ParaDos [[ParaDOS]] ROM in [http://cpcwiki.eu/imgs/5/57/Gerald_DDI-1_MF0004B.jpg DDI-1 interface]. It has a socket for removing and replacing different ROM chips. Then, I was thinking to myself.... Wait a minute! Let's see I can do the same thing on CPC 664.
So, I opened the CPC 664 case by removing seven screws, BINGO!!! It has a [http://www.maplin.co.uk/Module.aspx?ModuleNo=2530&&source=14&doy=14m10 DIL Socket 28-Pin ] ('''Maplin ref no: ''' BL21X, which it costs now 34p each, previously it was cost about 14p each) with [[AMSDOS ]] ROM installed top of the socket on the [http://cpcwiki.eu/imgs/f/f2/CPC664_PCB_Top.jpg motherboard], similar to [http://cpcwiki.eu/imgs/5/57/Gerald_DDI-1_MF0004B.jpg DDI-1 interface ] with the letters "FDD-ROM" next to it. I was very pleased, so I remove the [[AMSDOS ]] chip with "AMSTRAD 40015 7293-1951 8502AAA" printed on top of the ROM chip, and I replaced it with my spare ParaDos [[ParaDOS]] ROM chip - Thursday 23rd June 2005 09:40.
I closed the case and switched on my CPC 664 to see what happens, it says "PARADOS V1.0. ©1993 QUANTUM Computing" on the screen, it worked perfectly!! So, I switched off my CPC 664 and put all seven screws back on. Now, I can format 792k on each 3.5" discs or loading games from previous 792k formatted disks.
Unfortunately, it won't you run Logo2 on CP/M 2.2 disk, as it gives you an error message: "Retry (R), Ignore (I) or Cancel (C), if you press the "R" key to retry, it causes your computer crashed, as it needed the [[AMSDOS ]] ROM to load logo2 from [[AMSDOS]], but who cares, as I don't like using CP/M 2.2 or Logo2, anyways.
