Hi,
I tried installing Debian on an old Dell Precision T1700 and Radeon Firepro 2270 graphics, the installation went fine and booted to the Grub but I then get the following error:
*ERROR* radeon kernel modesetting for r600 or later requires firmware installed

How can I get around this? I can't get access to a terminal in recovery mode
