|
.Sh DESCRIPTION
|
|
This driver is for the
|
|
.Tn HP98544 ,
|
|
98545 and 98547
|
|
.Dq Topcat
|
|
and
|
|
.Tn HP98548 ,
|
|
98549, and 98550
|
|
.Dq Catseye
|
|
display cards.
|
|
This driver merely checks for the existence of the device
|
|
and does minimal setup, as it is expected the applications will initialize
|
|
the device to their requirements.
|
|
The Topcat and Catseye are nearly identical in common usage and only the
|
|
Topcat will be referred to from now on.
|
|
.Pp
|
|
The Topcat display cards are not user configurable.
|
|
If one is present on a system, it will always have a frame buffer
|
|
address of 0x200000 and a control register address of 0x560000.
|
|
These are the
|
|
.Tn HP
|
|
series 300
|
|
.Tn ITE
|
|
(Internal
|
|
Terminal Emulator) defaults.
|
|
The device can also be used as a graphics output
|
|
device.
