Basically, your kernel does not have support for the SIS chipset. Anyway, I have recompiled the Kernel (which is 2.6.9 do to the custom driver for the DVICO card) to support the IDE controller and this did not make any difference. I am using a Gigabit mother board model GA-8S661FXM-775 with a p4 on it. A pretty quick machine for this task. Did you compile the support into the kernel (i.e. it cannot be a module)? Did you update your bootloader (GRUB or LILO)? Did you reboot the system and select the new kernel? Note, also, that if you have support for some kernel options (such as Generic PCI IDE Chipset Support a.k.a. CONFIG_BLK_DEV_GENERIC), they will typically prevent loading of the SiS support (i.e. the generic IDE support is tried first, and it works, so the kernel doesn't try the SiS support).

[mythtv-users] Help: issues in trying to enable DMA on hard drives for mythtv...
Hello All, After a lot of work I have finally have my Mythtv box running. Thanks for all the great guides that are out there. Partically the one that was written by Jarod Wilson and Jani Talikka (for the Dvico HDTV digital card setup). I followed Jani Talikka's guide pretty closely to get my box running. One of the remaining problems that I have is the Live TV output is jerky. After searching the net I think this is related to me not being able to get the drives to use DMA. If I record anything the play back seems to be ok. So first up I will give a little info and see how we go.

/sbin/hdparm -c 3 -d 1 -m 16 -A1 /dev/hda This means: '-c 3' enables 32 bit transfers with sync through the pci bus, '-d 1' enables DMA operation, '-m 16' turns on multisector transfers (with 16 sectors) and '-A1' enables the driver read ahead feature.
