making a WD My Book external USB drive bootable


Greetings,

I'm running a LAMP machine with Debian and php4.4. I need the ability to run LAMP with php5.x in addition, but not all the time. My hope is to set up a Windows machine to, when needed, boot instead to Debian. I have a WD 500GB My Book external USB drive and want to configure it to be bootable (with grub?). I ran the Debian 4 netinst CD and was able to get the USB drive all set up--except I get a non-specific error when I try to install grub (or lilo) to /dev/sdb0 (which mounts as the root folder) from netinst. Can this be done? What's the process? Many thanks!!

can you not just add an entry to your grub list for your usb drive?

something like this. assuming your usb drive shows up second.
Code:
title    Windoze
map      (hd0) (hd1)
map      (hd1) (hd0)
root     (hd1,0)
chainloader +1
i believe there are ways to use php4 and php5 in parallel. i'm sure you can find plenty on google about that.

or if you are using apache 2 you can just enable and disable the modules with the following commands as you need. (assuming you have the php4 and php5 packages installed.)

Code:
$ a2dismod php4
$ a2enmod php5
or

Code:
$ a2dismod php5
$ a2enmod php4
afterwards restart apache
Code:
$ /etc/init.d/apache2 restart
