Can I really connect a normal S-VHS Display Device in this chipset ?

Linux kernel Framebuffer driver

I use the NeoMagic Framebuffer Driver in the Kernel 2.6.12rc5, since Kernel 2.6.8 with the following Configuration:

#
# Console display driver support
#
CONFIG_VGA_CONSOLE=y
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y   


# Graphics support
#
CONFIG_FB=y
CONFIG_FB_CFB_FILLRECT=y
CONFIG_FB_CFB_COPYAREA=y
CONFIG_FB_CFB_IMAGEBLIT=y
CONFIG_FB_SOFT_CURSOR=y  
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_VESA=y
CONFIG_VIDEO_SELECT=y
CONFIG_FB_NEOMAGIC=y
 

I normally use the 1024x768-16bit. It is good enough th play mplayer-videos oh this Framebuffer Device with the Option "-vo fbdev". If you use the devfs Filesystem, you must use the device /dev/fb/0 device.

the fb-settings are:

mode "1024x768-60"
   D: 65.003 MHz, H: 48.365 kHz, V: 60.006 Hz
   geometry 1024 768 1024 768 16
   timings 15384 160 24 29 3 136 6
   rgba 5/11,6/5,5/0,0/0
endmode
