Adj Monitor Refresh Rate

I am running a dual boot system, Win98SE and Win2000Pro.(AMD 2200 XP with 1GB of
ram).
I had posted about the monitor problem awhile back (OT Monitor MicroProcessor on
May 11,07)

Recently, I discovered that I could change the refresh rate on my monitor in
win2000 even thought the monitor's EDID was corrupted.; I had manually installed
the Envision 910 monitor drivers.

Then, I let Win2000 install my monitor as a Default VGA Monitor and then it
worked when I set the refresh rate manually and unchecked 'using EDID'.

I did this through the Catlyst Control Center within my ATI drivers. (Radeon
8500LE with the latest drivers).

Since I lost the EDID in my 19" Envision910 Monitor awhile back, I could only
get 60Hz refresh rate, even though I let Windows try to use 85Hz (display
properties).
No matter what I set it to, it would not change from 60Hz.At present, I am stuck
at 60Hz in Win98SE (somewhat hard on the eyes.. The ATI drivers (same version
number as the one I have installed in Win2000) don't have the Catylst Control
Center option of letting me disable the EDID detection
Is there somehow I can go into the Win98SE registry and tell Windows to set it
to the refresh rate that I want, overriding what Windows thinks it should do?
If this sounds confusing, I'm sorry.

I tried Franc Zabkar's great suggestion to my earlier post, to no avail.
Hopefully, someone out there can give me the solution or, at least, a path to
travel besides getting a new monitor or deleting Win98SE. :-)
