How to get ET4000 Crazy Dots working with NVDI?

1. Your autofolder should have the following programs in the following order:
   1. INIT.TOS, REDIRECT.PRG, NVDI.PRG, SLCT_DEV.PRG.
   2. Redirect simply changes output to your SVGA monitor. NVDI starts the drivers and Slct_dev enables you to switch to another resolution at the end of boot
2. Create your own VMG-4000 file. For 1024x768 @ 60Hz (perfect for LCD monitor), try the following:

VESA XGA Timing are:
Horiz Front porch 24
Horiz Sync pulse 136
Horiz Back porch 160
Vert Front porch 3
Vert Sync pulse 6
Vert Back porch 29

To convert to VMG timings:
Schwarzsch = Total length of black area (Front Porch+Sync Pulse+Back Porch)
Impulsstart = Start point of sync pulse (pixels or lines + Front Porch)
Impulslange = Sync pulse length (Sync Pulse)

so in this case the numbers for VMG would be (with the pixel clock set to 65Mhz):
Horiz Schwarzsch = 320
Horiz Impulsstart = 1048
Horiz Impulslange = 136
Vert Schwarzsch = 38
Vert Impulsstart = 771
Vert Impulslange = 6

Attention to sync polarity should also be noted, though i just select these to get the best picture, rarther than following the spec.
