Installing MacOS 7 from an external Apple CD300

Hey everyone,

been struggling to install 7.6.1 from my external Apple CD300 on the PowerMac 6100/60. It currently runs System 7.5 (yes, unupdated 7.5 - yikes)
I took the Image from the MacGarden and burned it with 1x speed. The disc shows up on the desktop and I can browse its contents. So the CD drive does work fine!

My problem is that I cannot get the PowerMac to boot from CD. I tried setting the cd "Mac OS 7.6.1" as startup disc. Reboot. Old 7.5 gets booted.
I tried the "press and hold the C key" thing, didn't work either. Was there another command for those old Macs? Dang I can't remember anything other than C. And google just spits out info on more modern cd / dvd drives.

Also - I noticed that when I restart, the Apple CD300 spits out the caddy before restarting. I have to switch off the PowerMac, put the caddy back in and only then switch it back on. Is there a way to make it stop ejecting discs on restart?

Any help appreciated! smile

I've never been able to use the C key to boot a vintage Mac off a CD. Try holding down Command-Shift-Option-Delete, which will force the Mac to boot from the next available SCSI device (in this case, your AppleCD 300)

Re: Installing MacOS 7 from an external Apple CD300

So, the topic can be marked as solved, though I haven't tried your solution yet LCGuy! (thanks anyway!)

I found a floppy deep in my closet. Must have put it there like 20 years ago. It is the last floppy I own. And what does a 90s Mac guy keep on his last floppy disk? Disk Tools of course! big_smile

So booted it from floppy and then installed from the external CD300. Case solved, PM6100 happily chugging along with 7.6.1.

Pardon me, gotta fight some aliens in Marathon! smile
