cannot find HD installing windows on R60e

tried to install a fresh copy of windows on a thinkpad R60e, setup would eventually give me this error:
setup did not find any hard disk drives installed on your computer

It turns out that this is a problem with windows setup not recognizing any SATA drives during install.

While poeple on teh nets all talk about using a floppy and installing SATA drivers from this floppy, i found this solution unacceptable.

Fortunately the thinkpad R60 (and perhaps many other computers) have an option in the BIOS that enables SATA compatibility mode. Enabling this mode solved my problem. Yey 2 hours wasted!

passwordless ssh/scp setup

I need to set up cron jobs which scp stuff all over the place. scp works best when you have rsa keys setup to allow you to ssh in without a password.

here are the steps to set this up (on solaris 8, possibly linux):

1) setup the public key and send it to the server
ssh-keygen -t rsa
[do not enter password when asked]
scp ~/.ssh/ [user]@[server]:~/

2) open a terminal on [server] and
mkdir ~/.ssh
touch ~/.ssh/authorized_keys
cat ~/ >> ~/.ssh/authorized_keys
rm ~/

Done! That was easy!

Note: if the above doesnt work for some reason, make sure that you do this to the .ssh dirs on the SERVER you are trying to connect to:
chmod go-rxw .ssh
