hey, thanks for taking the time to try to help me. here is the dmesg right after hdparm (well, just the valid section anyways)
root@banias:~# hdparm -d1 /dev/hdc
/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
root@banias:~# dmesg

and alos, i tried doing what you suggested with the modules.conf, however nothing is fixed
.
this is turning out to be a very big problem for me. ive noticed that whenever i get intense hard drive activity, my mouse slows down. also, yesterday i tried extracting a 200 mb file and that took about 10 minutes! i think that fixing dma will solve all of my problems....hopefully.
. went through the dma options one more time and enabled CONFIG_BLK_DEV_PIIX=y. now dvd's and dma work great. thanks for everyone's help.
