- Just take a look at http://www.vesa.com, you may get official
- specification for VESA 2.0 from there. However - it is in *.pdf format,
- file has over 5 megs, you must get also 1.8 megabyte Acrobat Reader from
- Adobe site, and don't try to discuss the idea of such a file size and
- format with anyone at vesa.com, as they look impregnated :(
