AmigaDOS asks for floppy by name, but it's "inserted" .. ?

Post by blakespot »

Say I have a demo ADF that is auto booting. It goes into AmigaDOS and then loads its files and runs. Say the name of the floppy is "Demo Floppy One" -- just after the AmigaDOS screen pops up, I get an "Insert volume Demo Floppy One" dialog. The volume is indeed named what it's asking for, as verified if I boot AmigaDOS and load that HFE image into the "drive."

Why would this happen? It's like it's loosing hold of the disk. I keep pressing Continue and it keeps asking for the disk.

This happens on a good # of demo disks I'm trying to load.

Any ideas? Tnx.

I can check, but give a link to this demo.

Sometimes there is a file on the disk that's missing or something in the programs coding that's looking for a file but can't find it, so the program assumes that the correct disk isn't inserted. Check if the disk actually works in a real floppy drive, not all adf's are a good copy.

I know it's just a small demo sitting on an autoboot ADF (.zip includes the binary, as well, for HD running) - but it's one example from the lot:

Tnx.

You don't talk about your Amiga : Which amiga are you using ? Which KS/WB version ?
Many demos are only compatible with A500.

I have an Amiga 2000 with both 1.3 and 3.1 ROMs on a switcher. The same happens with both ROMs on these disks. These are recent demos, within the last year.

Another example I hit today on the Unusual Suspects (August 2014) demo.

http://www.pouet.net/prod.php?which=63917

I get same error under both ROMs and have provided a screenshot of me digging around a little - perhaps it will help diagnose. Here you see getting a dir on the image in DF0: using a WB physical floppy in DF2: in order to access dir command. See I cannot switch to DF0: as working volume but can get a dir.

It's before any of the demo code is executing here - this is early in the startup scripts. The first thing this particular disk tries to do is run the 'cpu' command from startup-sequence and then complains it can't load it when I cancel out of the Insert UnusalSuspect Disk alert on boot of the image.

See the attached please.

Disk "Unusual Suspects" have commands amigados in C:
This commands need min. kick 2.0

I preparate this same problem on kick1.3 but without "System request".

As I said, I get the same result using Kick 3.1.

But there's more oddness... See my next post please.

Ok, it gets odder.

If I insert an image in Disk A and boot it -- it boots and runs fine if it has a custom trackloader -- if it's not booting into AmigaDOS and running s/startup-sequence, etc. Otherwise there is the issue.

Now, check this out.

I've attached a photo of the HxC Floppy Emulator menu software showing my loading of images in Slot 02 on the HxC. Note drive A has the highlighted Lemon_Point-Natsu_no_Gomu.hfe loaded, with another disk on drive B.

Now see the screenshot of AmigaDOS. It shows DF0: as Unreadable Disk and DF1: as Natsu no Gomu! I was able to access that image, which it would seem I loaded into Drive A, via DF1: (which should be drive B) and copy the file off of the image to HD. This seems especially crazy given my first statement -- that if the disk has a track loader, then what I put on drive A DOES boot and run...

What's going on here?

I have the HxC set to emulate drive A and B (DF0: and DF1:) and I have a physical external floppy that's DF2:.

This all seems very bizarre -- does this ring a bell as far as what could be going on?

Many thanks.

What you should check and do:

-> The Jumper settings.

-> A general virus scanning and cleaning... (This is not the first time that someone come here with similar behavior with a images/hdd virus infection)

How it works without external floppy?

The jumper settings are as the manual indicates for the scenario where the floppy cable has the "flipped" wires within. Pins 2 and 3, not 0 and 1 are used.

The cable has a section where 2-3 lines are twisted.

No viruses on any of the HD volumes.

How can you be sure ? Have you at least tried to reproduce the issue without any HD drive connected ?

This is solved.

Looking at the manual for jumper settings, I had been using the "twisted cable" settings because this is the cable I'm using:

There's twist. But, it isn't the kind of twist the HxC docs were referring to, it seems. I tried the no-twist jumper settings for DF0: and DF1: and things work fine. Glad to have this solved.
