“While the ATI Rage 128/128 Pro series of graphics cards are
supported by XFree 86, the xf86config and XF86Setup utilities both
fail to recognize the chipset and driver for this series. In
order to use your ATI Rage 128-based card to its fullest potential,
you need to edit your /etc/X11/XF86config file by hand after
configuring it with either of the afore mentioned xf86config or
XF86Setup.”
“Those with cards based on the Rage 128 chipset should add the
lines:
Chipset “ATI Rage 128”
Driver “r128”
Driver “r128”
to your /etc/X11/XF86Config file in the same format as detailed
below.”
“Those with cards based on the Rage 128 Pro chipset should add
lines detailed below to their /etc/X11/XF86Config file…”
