    ║  According to the Manufacturer, the ACB-2310/12 is 100% software and  ║
    ║  hardware compatible with the WD1003-WA2, but you are advised to do   ║
    ║  a Low Level Format to take advantage of the improved 1:1 Interleave  ║
    ║  that this controller offers.  Note that there is no on-board BIOS,   ║
    ║  so no DOS Debug LLF option is available.  Third party Formatting     ║
    ║  software is required, ie; Disk Manager(tm) or SpeedStor(tm).         ║
