When installing Win XP the setup program performs a compatibility-test of both the installed hardware and software, and the available disk space. The Preliminary System Requirements is as follows:
PC with 300 MHz or higher processor clock speed recommended; 233 MHz minimum required (single or dual processor system); Intel Pentium/Celeron family, or AMD K6/Athlon/Duron family, or compatible processor recommended
128 MB of RAM or higher recommended (64 MB minimum supported; may limit performance and some features)
Super VGA (800 X 600) or higher resolution video adapter and monitor;
1.5 GB of available hard disk space
CD-ROM or DVD drive
Keyboard
Microsoft Mouse or compatible pointing device
All these requirements are subject to change when the final version is released. In our case the generated Upgrade Report looked like this:
The hardware components that caused the warnings had already been removed from the system and did therefore not lead to any problems, but the required 1.5 GB of available hard disk space forced us to install a new hard drive. All present hardware were detected without any problems. When adding new hardware a message simply pops up in the notification area (if XP detects the hardware properly).
