sorry, one more question

i want to use DMA transfer with CD-ROM and Host
i must prepare a PRD to use.
i have a buffer and PRD structure
how can i assign my buf to PRD structure
(i do not know the really physical address of buf)

BYTE  buf[0x10000];
void AssignValue(void)
{
    PRD_EDDS.Size = size;
    PRD_EDDS.Seg = _my_ds();   ?????
    PRD_EDDS.Offset = (DWORD)buf; ?????
    PRD_EDDS.NumberAvail = Regions;
}

Thanks
