| |
This is on the ALim15x3 with the 2.5.69 kernel on a vpr matrix 200a5 laptop -- I just did this to get DMA5:
* set ide0=ata66 in lilo to get the 100MHz bus and DMA5 * add "hdparm -c 1 -m 16 -S 242 -k 1 /dev/hda" to /etc/init.d/bootmisc.sh
Nice results:
hda: 78140160 sectors (40008 MB) w/1768KiB Cache, CHS=77520/16/63, UDMA(100)
# hdparm -i /dev/hda
