+ select FONT_SUPPORT if USB_SISUSBVGA_CON
+ ---help---
+ Say Y here if you intend to attach a USB2VGA dongle based on a
+ Net2280 and a SiS315 chip.
+
+ Note that this device requires a USB 2.0 host controller. It will not
+ work with USB 1.x controllers.
+
+ To compile this driver as a module, choose M here; the module will be
+ called sisusbvga. If unsure, say N.
+
+config USB_SISUSBVGA_CON
+ bool "Text console and mode switching support" if USB_SISUSBVGA
+ depends on VT
+ select FONT_8x16
+ ---help---
+ Say Y here if you want a VGA text console via the USB dongle or
+ want to support userland applications that utilize the driver's
+ display mode switching capabilities.
+
+ Note that this console supports VGA/EGA text mode only.
+
+ By default, the console part of the driver will not kick in when
+ the driver is initialized. If you want the driver to take over
+ one or more of the consoles, you need to specify the number of
+ the first and last consoles (starting at 1) as driver parameters.
+
+ For example, if the driver is compiled as a module:
+
+ modprobe sisusbvga first=1 last=5
+
+ If you use hotplug, add this to your modutils config files with
+ the "options" keyword, such as eg.
+
+ options sisusbvga first=1 last=5
+
+ If the driver is compiled into the kernel image, the parameters
+ must be given in the kernel command like, such as
+
+ sisusbvga.first=1 sisusbvga.last=5
