Ron,
I bet you need to initialize the hardware with a call to the video bios,
so the card knows to display what is on B800. I don't know exactly what
happens, but I know that in the display functions I wrote for you we
display by writing straight to B800. I think the video bios resides
somewhere between A000 and C800 (but not in the areas it uses for scratch
space, like B800-C000 for color displays or B000-B800 (I think) for
monochrome -- there may be more). Could you step through until it does
that call?

Also, why doesn't it gunzip linux and jump to it?
