[syslinux] S3 Virge DX and vesamenu.c32

[Fuller, Erik C]

I can list all video modes, but in another reply it seemed 640x480 is
what you're interested in --

VBE version 1.2
Mode   attrib h_res v_res bpp layout rpos gpos bpos
0x0100 0x001b 640   400   8   4      0    0    0 
0x0101 0x001b 640   480   8   4      0    0    0
0x0110 0x001b 640   480   15  6      10   5    0
0x0111 0x001b 640   480   16  6      11   5    0
0x0112 0x001b 640   480   32  6      16   8    0

Looks like it has the video mode needed so it must lack linear frame
buffering.  

I appreciate the explanation.  Several of these older boxes are being
utilized as hard drive test beds where they net boot to the diag tools.

Could you list the output of vesamenu.c32?

If I remember right, though, S3V was one of very few video card of its
time which didn't support linear framebuffer, at least not through the
VESA BIOS.
