CMPLENGTH Monitor Setting
Just can't stay away
Just can't stay away


See User information
Several times since installing OS4.1u1 I have noticed a quick screen jump that looks like the screen got out of sync for one cycle or something. I changed the INTERRUPTS= setting to INTERRUPT= as others have suggested. I notice that CMPLENGTH is now set to 11 (CMPLENGTH=11). Previously, CMPLENGTH was set to 6 (CMPLENGTH=6) on SAM & ?A1. It's been set to 6 on my ?A1 for years. What is CMPLENGTH and should I change it back to 6 (from current 11 set by the Installer)??

Well, it doesn't have anything to to with sync, timings etc.

I don't remember exactly what it is for, but it has something to do with the length of the board name or the part of it which you want the driver to match on.

In general, you want it set to the length of the string after the equals sign in the BOARDNAME tooltype. So if e.g. you have BOARDNAME=Radeon, you should have CMPLENGTH=6.

In that case I guess CMPLENGTH=11 makes sense since the boardname listed by Ranger is "Radeon 9250". When I get around to reconnecting my ?A1, I'll have to check if the CMPLENGTH matches the internal video board name. I haven't seen the video glitch for a couple of days so maybe changing INTERRUPTS to INTERUPT had an effect. Thanks for the info. I learned something today

Didn't know that. Thanks.

So this is the most useless tooltype in the Amiga history
I don't see how it can be difficult to "read until \0".

As far as I remember, there was some good reason to have it. But I don't really remember what it was. Maybe it had something to do with making the icon valid for several different boards with the same brand, e.g. "Radeon" as well as "Radeon 9250" and "Radeon 9100" or whatever. All of those would be matched by comparing with "Radeon" with CMPLENGTH=6.

It's a valid explanation.
A tooltype called "BOARDNAME" could be used, making the whole thing easier to understand.
Anyway with the last Prefs/Screenmode, tooltypes are less important for the user. It's just that (s)he can find it confusing.
