Swap Floppy Disks or CD-ROMs using QEMU monitor

Published: 12 September 2024

Use the QEMU monitor by entering CTRL+ALT+2.

Run info block to see the device name. Most likely floppy0 in newer versions. However, older versions and older guides suggest fda.

Use the change command to switch the image

(qemu) change floppy "DISK1.IMG"
==> [silently accepted]

Go back with CTRL+ALT+1.

For a CD the process is almost identical. Instead of using floppy0 or fda, the device is likely ide1-cd0, sd0, or similar.:w
