Change removable media (floppy and cdrom) while running

[Creeper20428]

When using this emulator to run Windows XP, I encounter the program "setup". However, it tells me to insert the next image into drive A. Where's Drive A? Jamming a 1.44MB floppy into my laptop would probably destroy my computer and not help at all. So is there a way?

A possible solution is to upload the images into / (maybe A:) but I haven't had any luck using the filesystem yet...

Thank you in advance.

Agreed, a little button to switch out images would be awesome.

You would need this feature to install operating systems from the 1980s where they had like 10 install disks for each version of DOS.

I’m not clear on what the OS (BIOS?) is looking for to notice fdd changes. According to https://wiki.osdev.org/Floppy_Disk_Controller it sounds like changing port3F7_read to send a 1 in bit 7 when the disk door is opened (disk removed?) and again when closed (disk inserted?) should let us change the underlying buffer used by the floppy controller smoothly. Does that sound about right?

The confusing thing to me is how this works with respect to “selecting” fda or fdb—so if it’s cleared on a successful read or seek, we’d have to track the state for each of the two drives.

I also guess sometimes the guest OS could cause the floppy to pop out---that's something where noticing when unhandled commands are being sent would be good, because then we could see what to implement.
