    I don't quite follow your line of argument here as I currently have (
    following the reset in my earlier message):


    /dev/hdb:
    I/O support = 0 (default 16-bit)
    unmaskirq = 0 (off)
    using_dma = 0 (off)
    keepsettings = 0 (off)
    readonly = 1 (on)
    readahead = 8 (on)

    /dev/hda:
    multcount = 16 (on)
    I/O support = 0 (default 16-bit)
    unmaskirq = 0 (off)
    using_dma = 1 (on)
    keepsettings = 0 (off)
    nowerr = 0 (off)
    readonly = 0 (off)
    readahead = 8 (on)
    geometry = 1023/64/63, sectors = 4124736, start = 0


    which seems quite OK, given that the CDROM DMA noes not work.
