Debian does not impose hardware requirements beyond the requirements of the
Linux kernel and the GNU tools.
Rather than attempting to describe all the different hardware configurations
that are supported for the PC platform, this section contains general information
and pointers to where additional information can be found.
There are two excellent places to check for detailed information: the Debian
System Requirements
list and the Linux Documentation ProjectHardware Compatibility HOWTO.
For information on video card support, you may also want to look at the XFree86
Project web site.
Memory and Disk Space Requirements
You must have at least 4MB of memory and 35MB of available hard disk space.
If you want to install a reasonable amount of software, including the X Window
system, and some development programs and libraries, you'll need at least 300MB.
For an essentially full installation, you'll need around 800MB. To install
everything available in Debian, you'll probably need around 2GB. Actually,
installing everything doesn't make sense because some packages provide the same
services.
