Install and boot Windows on a second hard disk

I have a SATA disk and a EIDE disk, I installed Linux on the SATA disk and now I want to install Windows on the EIDE disk.
Because Windows must be installed on the disk that boot first, I entered BIOS and changed the boot order as this:
cdrom
EIDE disk
SATA disk
Then I installed Windows on the EIDE disk.
I want to configure dual boot this way: I changed BIOS boot order as it was previously (SATA disk before EIDE disk) and booted Linux, then I added these lines to /boot/grub/menu.list (on Ubuntu or Debian; if grub is not installed try apt-get install grub):
title WinXP
map (hd0,0) (hd1,0)
map (hd1,0) (hd0,0)
rootnoverify (hd1,0)
chainloader +1
That means Windows believes the EIDE disk is the first and SATA is the second, so it's happy and if I reboot and choose WinXP from grub menu it starts.

Running PHP scripts from command-line with WAMP (Windows Apache, MySQL, PHP)

On my old pc I installed Apache, MySQL and PHP singularly, and I made some PHP scripts to be runned from command-line, like this:

c:\php\php -f myscript.php
On my new pc I installed WAMP5 1.6.4, all was running fine (phpMyAdmin, my local website, php scripts pointed to by the browser) but php scripts launched by command-line reported
Fatal error: Call to undefined function mysql_connect() in myscript.php
Obviously I changed the php path to c:\wamp\php\php but with no results.
Solution: change the command to
c:\wamp\php\php -c c:\wamp\apache2\bin -f myscript.php
The -c option tells php to search php.ini in the directory specified, and that's needed because WAMP puts php.ini in Apache bin directory, while with a PHP regular installation php.ini is located in the php.exe directory.

About

This blog is born in August 2006 and it's about computing science: software reviews, configurations, tutorials, howtoes, for both Windows and Linux, hardware reviews, problems and relative solutions, tips and tricks, and everything else I get through in my computing related life.
The name ComputingArt was born as a "Computing Articles" contraction, but as pointed out by my friend csdk, it reminds to "Computing Art".
