WG: EIO DM-8401H ATA133 IDE Controller Card ( Silicon Image Chip ?!?)

[Michael Labuschke]

Hi
I bought an IDE Controller the other day ( non RAID version)
See  http://www.ivmm.com/eio/products_dm8401h.html
As ist stated there should be linux support.
No the problem is
(output from  cat /proc/pci

  Bus  0, device  17, function  0:
    Unknown mass storage controller: PCI device 1283:8212 (Integrated
Technology Express, Inc.) (rev 17).
      IRQ 11.
      Master Capable.  No bursts.  Min Gnt=8.Max Lat=8.
      I/O at 0xd800 [0xd807].
      I/O at 0xdc00 [0xdc03].
      I/O at 0xe000 [0xe007].
      I/O at 0xe400 [0xe403].
      I/O at 0xe800 [0xe80f].

The device is unknown
So i have patched the kernel and changed the old silicon image device number
to match my 
?unknown? device.

Dmesg gives me now
SiI680: IDE controller at PCI slot 00:11.0
SiI680: chipset revision 17
SiI680: not 100% native mode: will probe irqs later
SiI680: BASE CLOCK == 100

    ide3: BM-DMA at 0xe808-0xe80f, BIOS settings: hdg:pio, hdh:pio

and it finds both die drives connected to the controller
ide2 at 0xd800-0xd807,0xdc02 on irq 11
hde: attached ide-disk driver.

hdf: 195711264 sectors (100204 MB) w/2048KiB Cache, CHS=194158/16/63,
UDMA(33)

hdparm ?dt /dev/hde /dev/hdf

/dev/hde:
 using_dma    =  1 (on)
 Timing buffered disk reads:   86 MB in  3.04 seconds =  28.29 MB/sec

/dev/hdf:
 using_dma    =  1 (on)
 Timing buffered disk reads:   90 MB in  3.03 seconds =  29.70 MB/sec

So it works.. kinda..
As you see there is only UDMA 33 enabled ( both drive can do at least udma
100)
The driver seems right but the hack is REALLY bad ( works for me) 
You guys know much more about that stuff than i do.. maybe i could help.
