K7S8X mobo DMA issues
XP 2600+
1.5GB RAM
120GB HD IDE
80GB HD IDE (windows, not mounted)
TDK440N DVD-RW
random 52x CD-RW
Debian unstable
Kernel 2.6.10-K7 (installed via kernel-image-2.6.10-k7)
I've been having trouble with this board lately. It uses the SIS 746FX chipset. I am unable to activate DMA for the DVD and CD-RW drive. At the moment DVD playback is extremely choppy and I can't burn discs on either.
Also for the HD
Code:
# hdparm -Tt /dev/hda
/dev/hda:
Timing cached reads: 1028 MB in 2.00 seconds = 513.31 MB/sec
Timing buffered disk reads: 12 MB in 3.44 seconds = 3.49 MB/sec
Yeah, it's slow. When attempting to enable DMA on the DVD-RW for instance
Code:
/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
I read another thread that said to append noapic and nolapic at boot but that had no success. This thread http://www.linuxquestions.org/questi...ighlight=k7s8x said to compile this module into the kernel.
Code:
CONFIG_BLK_DEV_SIS5513: x x x x This driver ensures (U)DMA support for SIS5513 chipset family based x x mainboards. x x x x The following chipsets are supported: x x ATA16: SiS5511, SiS5513 x x ATA33: SiS5591, SiS5597, SiS5598, SiS5600 x x ATA66: SiS530, SiS540, SiS620, SiS630, SiS640 x x ATA100: SiS635, SiS645, SiS650, SiS730, SiS735, SiS740, x x SiS745, SiS750
Sorry for the horrid formatting. Anyway, the chipset is obviously not in that list of supported but the thread said to compile it in. Unforunately it looked like I could only compile it in as a module, and it was anyway. So still no result there.
Any ideas?

cat /proc/pci yields a "no such file or directory" hmmm |
