    Hello,

    now the sata drive is well inserted into the system, but i am not so happy about the speed of the disc; maybe i will try to improve it...
    The code of this device driver can manage size of the disc until 2 TeraBytes: larger HardDisk will be forced automatically to avoid addressing outside this limit.

    Cheers

    It seems that HDToolBox recognizes, despite the big size of the disk, a disc addressed in 28bit mode (RDB report this size and not the true size, see the picture above that show two different values).
    Here the tool in action...

    it is very similar to the third one, but it has a slight difference on the use of some lines accessing the Zorro bus. Both cards are compliants with the protocol and all the specifications made by Commodore for this series of computer. The fourth prototype seems to be more compatible in some situations that can happens with an Amiga 2000; it need test to confirm this thing.

    Cheers

    Hello,

    i am very happy because i have burned a CD, using MakeCD (the public beta) and isocd, from Commodore, to make an iso image file. The device driver seems to be ok and it will deserves to be tagged as version 1.0!! But even this CD is special because into it i have engraved forever some of my drawings and sources...
    This device driver is almost complete for MM devices and cartridges with magnetic disc, but in theory many others ATAPI devices can be used safely. ATA devices was never a problem but the removable ability of a compact flash card is not possible on a two-devices channel like this (card + device driver), especially if the CF is master: if you remove it, the device driver get confused by some replies that will be pure (in hexadecimal) $FFFF.

    Cheers

    Hello,

    wish you become betatester for this project? If yes, you need to own at least an A2000 with 68020 cpu and at least a Zorro card like a graphic card installed, to do serious test; a second machine like an A4000 is very good, to do further test on both computers.

    I have planned to print this card with machinery (just a couple of boards, to see how it work), so, i will do comunication here when a card is finished and ready to be delivered, with the software, that is complete.

    Best wishes
    Stefano
