I have a Micron 700FGx 17" monitor, and I was trying to work through the
second part of the vgadb(6) to see if vga(8) will recognize my monitor.
I found an entry in the database for a Micron 17FGx. I cannot figure
out how to go from the information in the monitor manual to VGADB entry,
particularly how to get shb, ehb, ht, vrs, vre, vt, hsync, and vsync.
Since the VGADB specifications are in terms of character clocks, this
seems to be from the generation of character terminals, which I cannot
find a description of. I have been reading the PC Upgrade Bible to get
an idea of how the video cards and monitors work. Ferraro, Richard E.,
Programming Guide to the EGA, VGA and Super VGA Cards is out of print.
Could someone could give me a time period in the 9fans archives or an
another book or article that would explain how to go from a monitor
description like the one below to a VGADB monitor entry. Russ has
talked about updating the graphics part of Plan9, but until then some
conversion formulas would help, especially when I do not have the system
installed to experiment with it.
Thanks for any references or information someone can provide.
