| Making a 1.44MB boot disk? |
Posted by: GnatGoSplat on 2011-10-29 12:39:54
I download the System 6.0.8.sea.bin files from the Apple website, then used Stuffit in OS X Lion to unpack them to "System Startup" and "System Addition" files. I wasn't able to figure out how to use Disk Utility in OS X to make a floppy, so I copied them to my PC and tried to write them to floppy using Rawrite for Windows. This appeared to work correctly, but my Mac Classic doesn't recognize the disks. What am I doing wrong?

The System folder needs to be blessed.

If it's a Mac Classic (model 1), then press and hold down Apple key, Option key, letter X and letter O. This will boot up System Software version 6.0.3 contained within the Mac's ROM chips. Don't hold it down forever, otherwise it will ask if you want to rebuild the desktop. This is because Apple key and Option keys held down in normal disk boot-up operation will invoke that procedure. If you end up with that response, simply select cancel.
Btw, this is the ONLY Macintosh model that has System software stored in the ROM chips.

You need to check the filesizes of the disk images. DiskCopy 4.2 images have a header at the start of the file. If you don't strip this, then the images won't write correctly with Rawrite.
If the images are 1,474,644 bytes then you need to strip the header. You can do this in OS X from the terminal:
dd if=disk1.image bs=84 skip=1 of=disk1-trimmed.image
The trimmed disk should be 1,474,560 bytes. You can then write this with Rawrite.

As you have a PC, why not use BasiliskII build 142 to emulate some 68k Mac?
The emulator reads and writes Mac HD disks fine and can be used to make boot floppies with disk copy.
It may be a rather long shot for making just one disk, but BII may be useful for other issues too.

I think newer JIT Basilisk 2s on Linux support floppies - B2 was constantly querying fd0 on my now HD-less P3 workstation

Yes, GNU-Linux hosts may be preferrable. I am using a BII build from September 2010 occasionally.
The file is hosted on Emaculation. Floppy support is working, just remember pressing Ctrl + F1 to tell the Mac a disk has been inserted.

Thanks, I got it working. I had the Windows version of DD, so I used protocol7's instructions and then rawrite for Windows was able to make a good disk.
