Can't make 7.5.3 System Disks on Mac OS X 10.7.3

Hello everyone,


I'm trying to restore a Macintosh Powerbook 190cs with System 7.5.3. I have a MacBook Pro with Mac OS X 10.7.3. I downloaded all 19 files (the first file is a .smi while the rest are a .part file extension)to a separate folder and discovered that 10.7.3 can't read .smi files. I get the error "legacy image should be converted" if it's a .smi file or "file not recognized" if it's a .part file..


I tried to copy the files to brand new floppy HD disks but they don't fit on them...


I've also tried the following website to get some help:


http://lowendmac.com/brierley/08pb/classic-mac-boot-floppy.html


No help because I need to extract the .dmg file from the .smi or .part file.


Is this merely impossible? Am I missing a step? I can't obtain an older Mac and was wondering if I can accomplish making the systems disks on my MacBook Pro with 10.7.3


Any help would be greatly appreciated!

Mac OS X (10.7.5)

Hi,


Very good! OK, so now you have a fresh, fully working System 7.5.3 on the PowerBook 190cs.


If one does not want a mere change of a previously installed system folder, it is possible to perform a Clean Installation (see steps 7 and 8 in article TA44452 below; disregard the information about 7.5.5).

As Jeff indicated, in order to reformat/erase the internal hard drive, a bootable tools floppy is normally required. You could create a suitable Disk Tools floppy (the downloadable Disk Tools PPC is OK for this purpose) on the now working PowerBook 190cs to begin with. Create the sector-copied floppy via the Make a Floppy command (under the Utilities menu) of Disk Copy 6.3.3.

Once the PowerBook 190cs has started from a bootable floppy disk, it is possible to drag-copy the system folder of the floppy onto an empty hard disk. This would create a temporary system folder on the hard disk, leaving the floppy drive free for subsequent transfers.


However, if transfers involve PC-formatted floppy disks, it is also necessary to have a PC Exchange control panel in the system folder. Therefore it may be wise to make a backup copy from the existing system of said control panel on a Mac-formatted floppy disk; the control panel could then be re-introduced into a temporary system folder).


It would be much easier to buy an inexpensive PC Card (PCMCIA) adapter for CompactFlash, and a small CompactFlash memory card. Insert the adapter with the CompactFlash card in one of the PC Card slots of the PowerBook 190cs. Reformat the CompactFlash card to Macintosh (HFS/Standard). Then either use the System 7.5.3 installer to install a system folder on the CompactFlash card, or just drag-copy the entire existing System 7.5.3 folder from the hard disk to the CompactFlash card. After this, it should be possible to boot the PowerBook 190cs from the CompactFlash card (do also check the Startup Disk control panel settings).


Various disk utilities can be installed on the CompactFlash card (such as Drive Setup 1.7.3).

One can also place the nineteen decoded System 7.5.3 files in one common folder on the CompactFlash card, allowing installations to be carried out from there.

Thank you Jeff and thanks again Jan! I will attempt to do a clean installation by referring to the Apple Support Article TA44452. That seems to be an ideal option as I only need to make a boot disk and from there I can launch the 7.5.3 installer on the Macintosh HD and select clean install.


To confirm, will this method remove all of the users private data and reset the O/S to it's default settings? That would be the main objective.

Hi Al,


A Clean Installation would create a new system folder (the previous one can be thrown away).


However, you would have to manually delete other files and folders elsewhere on the hard disk. Do not forget to empty the Trash (the Special menu). It is often a good idea to overwrite thus emptied space (this can be done through a special utility, such as an old freeware application called Burn 2.5).
