[9fans] Monitor timings - shb, ehb, vrs, etc.

[Joel Salomon <joelcsalomon@excite.com>]

I've seen this issue mentioned on the newsgroup archives again &
again, but never with  a real solution.  I'd like to use high
resolution (1600x1200) with my monitor, but that res isn't mentioned
in vgadb. vgadb(6) lists numbers to implement a resolution: shb, ehb,
vrs, etc, then says "The values given for shb, ehb, ht, vrs, vre, vt,
hsync, and vsync are beyond the scope of this manual page. See the
book by Ferraro for details." :-(

My monitor came with a list of resolutions and horizoontal and
vertical refesh rates. My question is: how do I get from this table to
the list of shb, ehb, vrs, etc. that vgadb wants?

If this is non-trivial but there is some one out there who can
generate these numbers, my monitor is a Hyundai P910+ with timings as
folows:
resolution    Horiz.(khz)   Vertical refresh(Hz)
720x400         31.5            70
640x480         31.5            60
640x480         63.7           120
800x600         53.7            85
1152x864        67.5            75
1024x768        68.7            85
1024x768        81.8           100
1280x1024       79.9            75
1280x1024       91.1            85
1600x1200       93.8            75
1600x1200      106.3            85
