    A disk on Module is basically a solid-state disc, or flash drive in other words. It should appear to the system like any really fast hard drive. They plug directly into either an IDE-PATA or SATA interface, so I think the normal disc drivers will work for these just fine. Why? Are you building an embedded system that will have one of the puppies?

    Ok. They why not use a standard pata-sata driver? The module itself will appear to the system as a standard disc drive.

    Disk on Module Driver

    Thanks for your suggestion
    My question is whether standard pata-sata driver will support Disk on Module?

    The sata driver should be part of the kernel, assuming you are building a 2.6.xx kernel, and not a 2.4 one. The 2.4 will certainly have an ide-ata driver which will work as well. Please read this wikipedia article about Disk on Module: Disk on module - Wikipedia, the free encyclopedia - it should help clarify some of your issues.

    It should be, provided that it has a boot loader installed on the root sector (0). Your BIOS should load that into memory and jump you there. Once there, your boot code should relocate that page (512 bytes, typically) in memory, and vector to the next instruction in the new memory location. In any case, you need to understand what your BIOS is doing and what instructions / interrupts it supports. That isn't a subject for this forum I believe.

    Disk on Module

    does it mean that I should Know complete BIOS source code and Boot Loader code. Did I get it correct?

    The basic problem is that i already have a embedded hardware with x86 (386) with eprom and disc on chip (DOC). We need to port the existing application into a general purpose IT-ATX box which will be using DOM.

    I'll be grateful if you could guide me through a brief process. What information i should need for this or from where I will get more information.
