this is what is in my hwtools file:


#!/bin/sh
#
#       /etc/init.d/hwtools (previously /etc/rc.boot/hwtools)
#

# Optimize interrupts. You might want to add parameters if you want
# to favor ttyS1 or ttyS0 or something else.
if command -v irqtune >/dev/null 2>&1; then
#   irqtune [PUT ARGS HERE]
   true
fi

# hdparm optimization
# Switches on interrupts during transfers and does multi sector transfers
if command -v hdparm >/dev/null 2>&1; then
#   hdparm -q [PUT ARGS HERE]
   true
fi

# configure QIC-02 interface
# see qic02conf(8)
# qic02conf --card= --port= --dma= --irq=



what do I need to uncoment? and do all I need to do is insert hdparm -d1-c1 
/dev/hdc ? if so where?

also I would like to get it working for hda so where would I put that 
statement?

the reason I ask is because others have said I need an init script.

thanks
