I previously ran Knoppix hdinstall on a dual PIII-500 machine with 768MB and an Adaptec U2W card with the boot drive at 80mb/sec.

Some time ago I upgraded to a dual Athlon 2100 MP system based on the Asus A7M266-D mobo. I like the machine a lot, but I switched over to IDE drives from SCSI and the performance difference is astonishing. The IDE drives are much slower.

I recently learned how to use hdparm to enable UDMA on my drives and speeds improved dramatically. The online tutorial that I used to do this mentions copying the commands that are used to turn on UDMA to /etc/rc.sysinit so that the proper speeds are used upon reboot.

I don't have that file in my /etc folder. Can anybody suggest the Knoppix equivalent, or do I simply need to create the file and add the hdparm -d1 commands for each of my three IDE drives?

Don't want to mess up a working system, so I figured I'd just ask first before making changes.

Thanks!
