Subject: [Oberon] Help: Display Init Strings for Native Oberon<br>
<br>
Does anybody remember how to create display Init Strings for Native<br>
Oberon?<br>
<br>
Background: I recently dumped my old CRT and replaced it with a TFT, my<br>
old<br>
NO installation switches the S3 Trio display via an Init string to 90 Hz<br>
refresh<br>
Rate, which the TFT does not understand.<br>
<br>
Although I remember, how to set the boot variables temprarily (see also:<br>
<a href="http://www.ethoberon.ethz.ch/native/WebConfig.html" target="_blank">http://www.ethoberon.ethz.ch/native/WebConfig.html</a>) I do not remember<br>
how to create these crude Init strings.<br>
