I'm new so first of all, hi! Here's my situation and problem.

I have an old German Powerbook 170 with System 7.0.1
I als have a macbook with OSX 10.4 and an external floppy drive.

I'd like to install 7.5.3 but the problem is that the System 7.5.3 01of19.smi won't fit on a 1.44mb floppy... Is there anyone that has a solution for this?

Thanks in Advance,

Jojojoost

The .smi files aren't copied to floppies, they're used to create floppies.

You need to open them on a classic Mac that has a floppy drive to make the floppies.

The problem is that I don't have a classic mac, only a Macbook with 10.4 and a Powerbook 170. There must be another solution...

Your method should work. I just copied the .smi file to a floppy using Mac OS X 10.5 and was successful. I have a very cheap USB floppy drive that I use for just such purposes and it had been quite reliable. Most of my floppies are getting very old and the floppies themselves are not as reliable as the drive.

Make sure you erase the floppy before you use it and select Mac Standard for the format. If the floppy is good, you should be able to simply drag the .smi file to the floppy to copy it. In my case after the copy completed I was left will about 300 bytes free on the floppy.

To install System 7.5.3, you will need to move all the disk image files over to the hard drive on the PB 170. All of these images need to be in the same folder and for an install, I place all the images on the desktop. Once all 19 of the image files are copied over, you need to double click the first image which will mount the disk image.

At this point you can start the installer from the mounted image, which will mount the remaining image files as needed. The install should run automatically.

Sometimes older floppies have bad blocks, so they will not format(erase) out to their full capacity and it is necessary to keep trying different disks until you find one that works.

You can use the same floppy to copy all the images form your computer running 10.4 to your PowerBook. Just move them over one at a time. You will not be able to install 7.5.3 until you have all the images copied over to your PB 170 hard drive.
