Error message: "Found more than one drive on IEC bus" with C128D metal and recent demos

Sorry for this lamer question. I use an C128D(metal), currently (although i have used C64 for years until i got room problems with the complete setup).
I have attached a 1541 ultimate and changed the internal 1571 drive to device no 10 by cutting the solder pads. The ultimate has dev no 8. This way i can watch many, mostly old, demos with 1541U. However, the most current demos always complain about more than one drive being enabled. Ok, i thought, plugging off the internal 1571 from the mainbord should fix the problem. I was wrong. The loaders still complain about more than one drive.
Am i wrong with my understanding that plugging off the internal drive also disables the ATN signal?

Wow that was fast. I'm very curious to test it on the real hw.

Would be cool if you could check both variants. Both should work, but i'm not so sure about various bus setups. The internal 1571 has the shortest physical path to the host computer's serial port, so it should all just work.

Anyhow, if your tests prove successful, i can safely add this feature to the loader. :)

Might shamelessly copy that, been too lazy so far :-)

As long as i show up in the credits under "help" or "additional code" or something, all is well. Open source works fine as long as there is proper attribution. :)

Hhhm, i just compiled it with acme (compiled without problems). However, when executed i just get the ready prompt as with run/stop restore. Maybe something went wrong when the src was copied into csdb? Or do i have to specify specific compile options? I disassembled code which showed that branch and jump targets were ok.

It executes a BRK if there's an error, such as device not present. Have you changed "lda #9 ; device number" to #10 for your setup?

So now some good new:

I tested FLT K9 orange with three settings and displayed active drives beforehand. Drive 8 = 1541u, drive 11=1571:

1.) No script ran -> Drive 8 and 11 shown as active.
Demo loader outputs error message that more than one drive is on the bus

2.) Ran script "OPEN 1,11,15,"M-W"+CHR$(119)+CHR$(0)+CHR$(2)+CHR$(0)+CHR$(0):CLOSE 1" to disable drive 11 -> Only drive 8 shown as active. Demo loader does not output error message but instead just hangs up.

3.) Ran Krills script -> Only drive 8 shown as active. Demo loader works perfectly.

I now created a folder 0_scripts in the base dir of the 1571U and put all those successful and unsuccessful code attemps into a d64 in this folder. This way i can quickly disable the internal 1571 before running any demos.
As remarked by Skate, the d64 should be mounted before running any contents. If they are run directly, you will not receive the "ready." prompt after code has been run.

Okay, cool, but do both variants work nicely, with and without "tightloop" enabled? :)

I did not test this up to now. Currently tightloop = 0.
