Change CDROM image right after restore a state

[alejandrocobo]

Hi,

I'm trying to change the CDROM image from a saved state. The VM is saved with a dummy CDROM image. I'm using Windows 95 OSR 2.1.

Is there a way to change the iso image right after the state has been restored using the libv86.js without having to re-compile?

Thanks.

I've achieved something:

In the initial VM, I use this:

cdrom: {
            url: "dummy.iso",
        },

With this, I can see the content of the dummy image (it is a single testing file). Once Windows 95 has booted, I save the state.

Then, when I restore it, I do this:

emulator.add_listener("emulator-ready", function () {
        emulator.eject_cdrom();
        emulator.set_cdrom({
            url: "new_image.iso",
        });
    });

This waits for the state to be restored, "ejects" the dummy image and "inserts" the new image. Since the new image is a 650MB file, it takes a very long time. But it works fine.

I've tried this in the initial VM:

cdrom: {
            url: "dummy.iso",
            async: true,
            size: 8966144,
            fixed_chunk_size: 1024 * 1024,
        },

After Windows 95 has booted, I go to My PC, double click on the CDROM drive but it appears empty, with no files in it (while the image actually has a file).

Despite this fact, I try to insert a new image:

emulator.add_listener("emulator-ready", function () {
        emulator.eject_cdrom();
        emulator.set_cdrom({
            url: "new_image.iso",
           async: true,
           size: 681605120,
           fixed_chunk_size: 1024 * 1024,
        });
    });

But it won't mount the new image.

HTTP 206 Partial Content is available and, in fact, Windows 95 boots in async mode.

I don't know how to proceed from here.

Thanks.

Sometimes Windows does not work properly with ejecting CD, can you try without dummy.iso in the state file?

After Windows 95 has booted, I go to My PC, double click on the CDROM drive but it appears empty, with no files in it (while the image actually has a file).

Probably #1349

Sometimes Windows does not work properly with ejecting CD, can you try without dummy.iso in the state file?

Do you mean to save the state with just cdrom: {}, and then setting a image after restoring the state?

#1349 is what I see. In fact, the behavior is the same with the empty drive and the "Cd" label (while the label is not that).
