Startup Error 84

Startup error code 84 pertains to Profile and Widget drives. It means the boot blocks are damaged. There are three possible fixes.

Fix one involves double-reformatting the drive---first under Lisa OS, then under MacWorks XL. Double-reformatting the drive is time-consuming and it only applies to unmodified computers. You can't use this method with a Macintosh XL Screen Modification Kit unless you pull the 3A ROMs and reinstall the old ROMs. Also, double-reformatting doesn't always work.

Fix two involves reformatting the drive with MacWorks Plus version 1.0. 18 or later. Holding down the Apple and the left Option keys while double clicking the MW Install icon opens the program in the expert mode. Expert mode recognizes most unmountable drives and gives the option to you to reinitialize them. Afterwards, the drive may or not be bootable.

Fix three involves sending your drive to Sun Remarketing. Using a special machine, Sun technicians can do a low level format, which rewrites the boot blocks, then a high level format, which installs the latest version of whatever operating system you've been using (Lisa OS, MacWorks XL, or MacWorks Plus). This method always works and it's a lot less painful than having to buy a whole new drive. SCSI drives can be repaired by using utilities such as Norton Utilities.

Sad Mac error code OF0084

Sad Mac error code OF0064 pertains to any Lisa hard drive formatted under MacWorks 3.0 or MacWorks XL. At the time the original MacWorks was written, other Macs weren't equipped with hard drives. The old System software, written to 400K floppy disk specifications, has trouble dealing with big disk directories. If over 100 files accumulate, everything slows down and eventually fails. Error code OF0064 generally indicates an irreparable problem with the System & Finder. There are three possible fixes. The first fix involves rebooting from the hard drive while holding down the Option key. (If you are looking at the sad Mac screen hold down the left option key and press and release the power switch button.)If MacWorks itself is OK, you'll get a floppy disk icon with a blinking question mark. At that point, insert the MacWorks System disk. It'll load, you'll get the standard "Welcome to Macintosh" signon message, and, shortly thereafter, both disk icons (the floppy disk icon and the hard disk icon) should appear. Now all you have to do is replace the System files. To do that, open the System folder on the MacWorks System disk, select the System & Finder and drag them to the hard disk. A dialog box asking whether to "Replace items with the same names with the selected items?" will appear. Click OK and thats all there is to it.

The second fix applies when the hard drive icon doesn't appear. In that event, you need a special disk called Hard Disk Mount. Hard Disk Mount may be obtained from Sun Remarketing for a cost of $15. Here's the complete repair procedure:

1. If the computer is on, reach around the back with your right
hand and press the reset button. If the computer is off, turn it
2. Immediately after hearing the first click, tap any key but Caps
3. When the STARTUP FROM menu appears, insert the HD
Mount disk and click the disk drive icon or hold down the Apple
key and press the 2 key (the one on the keyboard, not the one
on the keypad) to proceed.
4. When the HD Mount disk ejects, you'll see a floppy disk icon
with a blinking question mark. "Hard Disk Mount" will be written
under it.

From here on, the repair is the same as above. Insert the MacWorks System disk, and shortly thereafter, both the floppy disk icon and the hard disk icon will appear. Replace the System files and that's all there is to it.

Note: Hard Disk Mount is for repair purposes only. It's not an upgrade! Replacing regular Mac Works with Hard Disk Mount (using the Hard Disk Install Utility) is not recommended.

The third fix is to replace MacWorks XL with MacWorks Plus. MacWorks Plus provides full 128K ROM emulation, including the HFS file system, support for hard drives, support for SCSI drives, and it lets you use later versions of the Macintosh System and Finder. Install MacWorks Plus and you'll never see error code OF0064 again.
