I attached a Toshiba DVD-ROM at the ASUS A7V133 Promise controller.
The highest transfer mode I can use is Multiword DMA 2, though I activated
the DMA-Option in the IDE-kernel configuration.
>hdparm -i /dev/hde
�/dev/hde:
�Model=TOSHIBA DVD-ROM SD-M1502, FwRev=1008, SerialNo=2100807146
�Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
�RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
�BuffType=unknown, BuffSize=128kB, MaxMultSect=0
�(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
�IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
�PIO modes: pio0 pio1 pio2 pio3 pio4
�DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 *mdma2 udma0 udma1 udma2
�AdvancedPM=no
�Drive Supports : ATA/ATAPI-5 T13 1321D revision 3 : ATA-2 ATA-3 ATA-4 ATA-5
If I try
>hdparm -d 1 /dev/hde
�/dev/hde:
�setting using_dma to 1 (on)
�using_dma � �= �1 (on)
to active the UDMA-Modes the drive is not accessible. Mount and file access
fail, but
>�hdparm -i /dev/hde
�/dev/hde:
�Model=TOSHIBA DVD-ROM SD-M1502, FwRev=1008, SerialNo=2100807146

shows no difference.
after I tried to access to drive dmesg shows:
ISO 9660 Extensions: Microsoft Joliet Level 3

ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hde: tray open

But I did not opened the tray.
After setting back with hdparm -d 0 the drive is functional again.
If I use the VIA-Controller with the same drive I am able to activate udma2
successfully.
Any ideas?
Thanks
