VIA KT266 Support

[daemonxx]

Hello,
I am having some trouble getting my Gigabye 7VTX Motherboard to run under Linux. It seems that my WD 20GB Hard drive doesn't want to run in DMA mode. Issuing the command hdparm -c1 -d1 /dev/???? doesn't seem to work. It says ULTRA_DMA_??? INVALID MODE. I have Generic DMA enabled in the kernel and have had success with my Intel motherboard. Also upon booting up, I get an error that says VIA SOUTHBRIDGE UNKNOWN. I am assuming that this is the problem, but doesn't the latest kernel support my chipset? I have tried LM 8.0 with the newest kernel out there and still no luck. Any help appreciated..

Have you selected VIA82CXXX under IDE chipset support?

Yes, I have that enabled in the kernel. It still gives me an error message saying "UNKNOWN VIA SOUTHBRIDGE" when booting up. I would thought they would have it supported in the latest kernel. Oh well, thanks for your reply.

Have you checked the help files for all the options under IDE support/bugfixes to see if there is something else that's necessary?

Have you read the kernel docs on chipsets or tried a search for the error at Google?

i dont know what you are doing wrong but wanted to let you know that mine works. just its better to know that you are working at a goal that is acheivable than not sometimes. at least you know it works somewhere in the world?

Thanks for the reply, I tried to search google and read the docs but nothing came up. I will try and work on it tonight when I get a chance. At least I know it is now a bug... Thanks

Hold on. Don't go yet.

Are you sure you've enabled all that's required. My Asus CUV4X with Via North and Southbridge works great with the following kernel config.

Hmm, my Gigabyte 7VTX uses the KT266 chipset for the Athlon. I enabled the Via support and the dma support in the kernel. The syslog gives me an error saying "VP_IDE UNKNOWN VIA SOUTHBRIDGE". It also failed to probe the IRQ's for the IDE Devices. For some reason the kernel has a problem detecting the Via Southbride. I am trying to search google for the answer but can't find anything.
