Macintosh IIvx

There are a couple of alternative procedures, depending on whether you want to keep any files on the hard disk or not.

At this point, I will assume that you do not wish to erase the whole disk, if possible (may become necessary anyway, if the logical structure is severely damaged).

When you have started from the floppy, you should see a hard disk icon ("Inside the Machine"?). If not, post back. Locate the existing System Folder on that hard disk. Click on the name and rename that System Folder (call it OLD System Folder). Move the System suitcase out of OLD System Folder (place the suitcase inside any other folder on the hard disk; remember where). Finally, locate the System Folder on the Network Access floppy, and drag-copy this System Folder onto the hard disk.

You should now have both an OLD System Folder (which does not contain a System suitcase) and a System Folder (that is, a temporary one copied from the floppy) on the hard disk. Choose Restart from the Special menu. The computer should eject the floppy and start from the hard disk.

Download HFVExplorer (under the "New battery on Performa 475 - no boot" topic in this section, AppleIIFreak has indicated where to find the program; otherwise try a Google search). Install the utility on the PC.

Download Disk First Aid 7.2.2 onto the PC (keep the .bin file as it is).

Locate a Mac-formatted 1.4 MB HD floppy (preferably empty, or at least with approx. 100K free space).

You may have to temporarily unload any anti-virus software. Double-click on the HFVExplorer icon in order to launch this PC program. Insert the Mac floppy. Refresh by pressing F5 on the PC keyboard. The Mac floppy will appear as a white icon (top) in the left HFVExplorer pane.

Locate the Disk First_Aid7.2.2.sea.bin file (possibly a truncated name) on the PC. For example, if the file is directly at the C: level, select the (yellow) C:\ icon in the left HFVExplorer pane and the file will appear in the right window. Drag the file from the right pane onto the (white) Mac floppy icon in the left pane. A Select copy mode dialogue box will appear. Select "MacBinary2" from the list, then click OK. You will notice activity from the floppy drive (the program does not provide a progress report, so keep an eye on the floppy drive indicator light). When finished, immediately eject the floppy (which should contain a self-expanding archive, Disk First Aid 7.2.2.sea).

Move to the IIvx. Insert the Mac floppy and drag-copy the .sea file to the hard disk. Double-click on the Disk First Aid 7.2.2.sea to unpack the application. Launch Disk First Aid, select the hard disk and click to verify. What does Disk First Aid report? Please post back.

Mulligan,

Yes, reformatting the hard disk would probably be the best solution in this case.

There are two possibilities.

You should be able to carry out a high-level operation from the existing Network Access floppy. Try this: Select (click on) the hard disk icon. Choose Erase Disk from the Special menu. When ready, drag-copy the System Folder of the Network Access floppy onto the hard disk (this will give you a temporary system, in order to free the floppy drive for subsequent transfers).

A more thorough low-level operation would require a modified Network Access floppy, with a formatting application such as Apple HD SC Setup 7.3.5. For details about this, see the "New battery on Performa 475 - no boot" topic.

The principle for the transfer of the nineteen System 7.5.3 files is the same as for Disk First Aid (as in my previous message). Make sure that Aladdin Expander (or any other program) does NOT decode the downloaded .bin files on the PC. You will need empty Mac-formatted 1.4 MB floppies (you can use the IIvx, running from the temporary system, to reformat normal PC diskettes). The .bin (MacBinary) decoding will take place within HFVExplorer. Copy the resulting files (one .smi and eighteen .part) to a common folder on the IIvx hard disk. When finished, start from the Network Access floppy and move the temporary System Folder on the hard disk to the Trash (empty the Trash from the Special menu). Double-click on the first = .smi file to mount the total disk image. The System 7.5.3 installer will be found in the mounted image.

BTW, the standard way of ejecting a floppy from a Macintosh computer is to drag the disk to the Trash.

If you erase the hard disk (high level, via Erase Disk), copy over the temporary System Folder, and then transfer/run Disk First Aid, do you get the same result?

Jan

Mulligan,

The startup disk is the top right icon.

Insert the bootable Network Access disk. Start the Mac. The Network Access floppy icon should be top right, the hard disk icon below.

The message indicates that the IIvx has started from the hard disk. One cannot erase/reformat the Macintosh startup disk.

Jan

Strange. Where did you find the 1.054 MB value? If you reformat a PC 1.44 MB HD diskette to Mac format in the IIvx running from the temporary system (just insert the floppy; a message will appear offering to initialise it), and then double-click on the floppy icon, the open window should indicate something like 1.3 MB available (this should be just enough to hold each of the nineteen System 7.5.3 files).

Jan

Mulligan,

Please re-check that all files are there, that is 01...19.

Also, do check that all files have been properly decoded (the first should automatically have received the .smi suffix, all the others .part; not .bin).

Are all files in a common folder?

Does the first (.smi) file have a special icon (not a generic document symbol); if not do try to rebuild the Desktop by holding down the two keys Command (Apple) and Option (Alt) while starting from a temporary system folder on the hard disk.

Jan

Mulligan,

Normally, the System 7.5.3 download works well. Apparently, in this case, something is not working as it should. It could be that one (several) segment(s) has (have) been damaged. It is also possible that the hard disk driver software is not OK.

Is it true that you still are able to run the computer from the temporary system folder on the hard disk?

What does Disk First Aid report when you try to verify the hard disk now?

Have you tried to re-initialise the hard disk, or merely to update the hard disk driver software, via Apple HD SC Setup 7.3.5?

I can understand that you only reluctantly wish to repeat the downloading/transferring of nineteen files. Therefore, in order to check whether the machine is capable of mounting a self-mounting disk image (.smi) at all, one idea might be to download and transfer (for example) Drive Setup 1.7.3.

The system folder of the Network Access disk is very limited, and will only let you run a few basic programs.
