WARNING: Cannot open /dev/cdrom (No such file or directory) SheepShaver V2.4 by Christian Bauer and Mar”c” Hellwig The following is the console output from $. I’ve also tried fiddling with the bootdrive value in sheepshaver_prefs – also no change in behaviour. I’ve tried the “Troubleshooting” hint in the blog of replacing “disk” with “cdrom” in the line which reads “disk /home/pi/mac9x/9.iso” in the file /home/pi/.sheepshaver_prefs – to no avail. The response is a grey background with a 3.5 floppy icon with flashing question mark “?” – this suggests to me that the emulator is bootstrapping from the ROM ok, but that I am failing to boot from the CDROM ( i.e 9.iso) I did the OS 7 install with Mini VMac – great fun! Now I am trying to get OS 9 running with SheepShaver per the instructions in the video, but I’m hitting a snag.Įverything follows the video fine until I try to boot from the 9.iso image.
