@TheGreatCodeholio:
Regarding the new FDC emulation, are we now supposed to be able to switch multiple floppies under win9x like we can with CD-ROM's (as long as we of-course refresh the Windows Explorer window)? And we will have 32-bit disk access with the floppy controller along with the hard disk, right?

Codeholio is not finished yet according to the latest git updates.

Yes, I already knew that. What I'm asking is if those two things is what we will have when he finishes the FDC emulation.

Codeholio has addressed both issues:
DOSBox-X branch
DOSBox-X branch

OH, okay! Now I see where the confusion is. DOSBox SVN (clean vanilla) actually I know does support this, Codeholio must just not be aware, maybe? (see Mounting multiple floppies to same drive (CTRL+F4 Switch))

I recall that DOSBox has never really supported the multiple disk swapping mode unless "boot" is used directly with multiple disk image files, or if multiple .iso images are given when mounting a CD.

You should be able to do multiple floppies with disk swapping if you do something like:

boot "disk1.img" "disk2.img" "disk3.img" "disk4.img"

It was added to DOSBox vanilla (not just ykhwong's build, read the auto-generated SVN changelog by Qbix) since SVN r3808.

I verified that Codeholio already has that feature in dosbox-x. Test Ctrl-F4 with a few floppy images mounted by the imgmount command to a single drive letter. It will work in the dosbox-x shell.

That's true, it works in the shell...... But is it possible for Codeholio to make it so we can some time in the future, just as an idea, to be able to swap multiple floppies under win9x like we can now with CD's?

As shown in the other post, Codeholio is aware of the idea. Even though a floppy drive appears simple because it is an older device, it has been discussed that this emulation is a hard problem. Perhaps we can offer our help to him so he is not shouldering all this work by himself. 😀

Good point. We all can still test Codeholio's great work, even if it is just from his earlier VS2008 builds for public use. If he does decide to make another win32 build, after the FDC emulation and whatever else is finished, I'll always be glad to give my input by testing and any bug reporting. 😀

Anyway, keep up the great work you guys!

Maybe this has been said before, but when I am trying to install windows 3.11 from floppy I cannot eject the first disk because it is still "in use" and since windows looks at only the A:/ drive inserting a diskette into the B:/ drive won't help. Furthermore, I get a C++ error when I try to set the cycles manually, doesn't matter the integer I put in, it crashes.

You could make images of your floppies and use imgmount to mount them and cycle via ctrl-f4 through them. And why can't you just eject the floppy or rather how do you change floppies to receive that message?

For Win3x it works to simply dump the contents of all the install floppies into a single folder and run the install from that folder.

As for the halt on cpu cycles?

Does choice of core make a difference?

Nope :3

It works with DAUM's build, so maybe something got broken in the fork. Or, should I say, modification.

The cycles function works fine for me. The error doesn't seem reproducible, at least from the few details given.

I am running windows 10 dev preview, x64bit, core i7, ATI 6750m, 16gb ram, lenovo laptop.
