Personally I would just install the base system from your 2.2 (potato) CD and then upgrade to Woody (the version that will be released soon). The reason I suggest that you do this is that 2.2 will be obselete very soon, and the software that comes with it is ancient. E.g. XFree86 is version 3.3.6 rather than XFree86 4.1 in Woody, and you will have a lot more trouble configure XF3 than XF4.
However, it would probably be much simpler for you if you simply download the Woody boot-disks - more info here
. You will also want to read the installation manual
- Debian isn't for the faint-hearted, but is delightful to use if you can be bothered to read the documentation (some people unfortunately can't).
