A Step by Step GuideĪfter that little tour of the dd command on OS X, here are the step by step instructions for creating a bootable floppy disk from OS X. Sounds confusing? It is – but this is the magic step which seems to be missed from many discussions about using dd. The trick is to unmount the contents of the floppy disk whilst you still have the disk itself mounted. If you try to run this, you’ll be told that the device is busy. You’ll see your disk listed, but the field of interest is the first column – it will probably say something like /dev/disk1 – and that is the correct value for OUTPUTFILE.īut you’ll hit problems again.

If you have a floppy disk mounted, go to Terminal and type the command df -h.

But how do you point OUTPUTFILE to the floppy disk? When Mac OS X mounts a floppy disk called DISKNAME, it creates a location for it at /Volumes/DISKNAME, but if you try to use this with the dd command, you will get an error. For example, if the image is system7.img and it’s in your home folder, you need to replace INPUTFILE with ~/system7.img. This seems simple enough, but you need to know a bit of Unix to get the paths correct. The command for creating a Mac boot disk is: dd if=INPUTFILE of=OUTPUTFILE bs=84 skip=1 Complications of OS X Some extra parameters are needed when dealing with Mac Disk Copy images, because there is some extra information in the header of these files that we want to strip out. At least, it should be that simple, but it isn’t quite. Where you would replace INPUTFILE with the filename (and path) of the disk image and OUTPUTFILE needs to point to the destination (a floppy disk in our case). The format of the command’s usage is fairly straightforward: dd if=INPUTFILE of=OUTPUTFILE The dd command can be used to duplicate any disk, and it can be used to take a disk image file and write it to a floppy disk byte by byte. One of these can be used to make boot disks.

Making Boot Disks Using ddĪll was not lost due to one simple fact – Mac OS X is a Unix variant, and therefore it has all of the standard Unix tools available. Earlier this year, I found myself with three old Macs, none of which would boot, and a G5 with Mac OS X 10.5 Leopard installed that was seemingly useless for this task without the Classic environment. smi files, you need to make a boot disk using one of the other two methods.īut both Disk Copy and.

smi files need to be copied to one location – in other words, you should be able to boot the Mac you want to install them on. smi self mounting images – often split across multiple filesĪnd herein lies the problem: Multiple. You can also find useful items in their archive, such as the 7.5 Network access disk, which allows you to boot into System 7 from a floppy.ĭepending on the file format, preparing these boot disk follows various routes, but most of them rely heavily on one of the following three items:

Apple very kindly makes various versions available for free – most notably System 6.0.8 and 7.5.3. In order to keep our classic Macs alive, we need ready access to boot disks and install disks so that when the need arises they can be recovered.

It was more of a hassle than a problem, but it became a serious sticking point once I upgraded to Leopard. What did interrupt my Classic Mac activities was a number of hard drive issues that required multiple reinstalls of various versions of the Mac OS on different machines. Most recently, I’ve become the proud owner of an iPhone 3G, which may finally stop me hunting for an elusive MessagePad 2100 on eBay. It’s been almost two years since I last wrote for Low End Mac, but my love of all things Apple hasn’t waned.
