As I wanted to use an older Notebook with ATI Radeon Xpress 1250 Graphics Chip, I needed to get an recent driver.
Sadly, ATI/AMD does not provide drivers for Win 8.1 / 64 Bit for this old chips.
However, with Digitalflem you can create your own "old/new" Driver:

1.) Download the ATI Catalyst 10.2 Windows 7 | Vista (64-bit) legacy driver, start the installation and abort it - so you got the files unzipped
( i.e. from http://downloads.guru3d.com/ATI-Catalyst-10.2-Windows-7-%7C-Vista-%2864-bit%29-download-2478.html )

2.) Download the latest ATI Catalyst Driver for Windows 8.1 (64-bit), start the installation and abort it - so you got the files unzipped
( i.e. from http://support.amd.com/de-de/download/desktop?os=Windows+8.1+-+64 )

3.) Download and install Digitalflem 2.0 from: http://digitalflem.mydiscussion.net/download

4.) Start Digitalflem 2.0 and follow the Guide: http://digitalflem.mydiscussion.net/guide
