Summary MESS-specific 06373: apple2gs (all sets): GS/OS freezes and corrupts data if more than one floppy is inserted
Description If you insert more than one floppy image into the emulated IIGS while it's running GS/OS, the system will freeze until you eject the second floppy. Data on the first floppy will be corrupted as well.
Steps To Reproduce 1. Obtain some GS/OS floppy images - I used the .po images from
2. Insert Install.po into floppy #3 (1 and 2 reject .po images) and boot from the floppy.
3. While in the GS/OS installer screen, insert Synthlab.po into floppy #4. GS/OS will lock up.
4. Eject Synthlab.po. GS/OS will start responding again.
5. Reboot the emulated system. Install.po is no longer bootable - you get an error loading START.GS.OS instead now.
