I have to move from PC to PC bringing my harddisk which is removable.
The PCs uses differnt cards and monitors. Both of them are Super VGA 0.28in
display but they have resolution of 30 Mhz only.
One of them is an autosync and autosize monitor. Both 14in size.
Here is a first attempt at an idiot-proff Xconfig that can work on all the
supported chipsets provided the auto detection software works. It works by
giving more frequency options so that the auto clock detector can lock on the
nearest one. The accuracy of the clock detector is +- 1 Mhz so just copy
entries for the other 2 values.
I also notice that the most common clocks are 25 for 640x480 and 36 for 800x600.
The clocks should not exceed the bandwidth of your monitor but it does no harm
but you lose clearity. For example most standard SVGA monitors have bandwidth of
less than 30Mhz. If you can afford the multi-sync 16-in monitors, you may be
able to afford workstations.
If it failed, it meant that the auto-detection software failed so you
must do it manually, which is most likely to be due to incompatible chipset, or
clock circuitry.
If you have 80Mhz bandwith monitors, you have to add the mode into
the line Mode. However you'll start with the lowest resolution of 640x480.
You can switch from mode to mode by typeing ctrl,alt,+ keys together.
