cant edit /etc/init.d/boot.local

[esyed]

I found a link on the web that mentioned how I can speed up my box. It suggested to add
hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda
since I did that and did a reboot. I no longer can boot into suse. on startup the os just hangs. Its same even if i try to login in failsafe mode. I got knoppix, I browsed thru /mnt/hda3/ and wanted to comment the line in /etc/init.d/boot.local but I cant coz it says the file can be opened only in read only mode and I dont know how I can login as root and access /mnt/hda3

I tried to login as su, and give the suse root passwd but still I cant edit the file.

I am sort of frozen and need to get some imp. work done. Plz help!
(my distro suse was so damn slow, which led me to do this in the beginning).. now it actually backfired!!

1) Answer #6 (http://www.knoppix.net/wiki/User:Harry_Kuhman).

2) if you need to be root, and I doubt that you do, use the su or sudo commands, use the man command to learn more.
