Line 1:

The '''''Mac OS 8.1 Emergency Handbook''''' is '''Apple Computer, Inc.'s''' owner-level troubleshooting booklet shipped with Mac OS 8.1, '''© 1998 Apple Computer, Inc.''', '''69 pages'''. Its own subtitle: "Includes troubleshooting, hard disk repair, and software installation information". The scan is OCR'd and searchable, though the OCR is poor in places.

Of the Apple documents on this wiki that are not service manuals, '''this is the one closest to actual fault-finding''' — it is written for the user, but several of its procedures are the first things a repairer does too.

== Contents ==

* '''1. Problems Starting Up''' (p. 1) — computer won't start up or restart; single icon in the middle of the screen; computer freezes; message appears; normal desktop doesn't appear; hard disk icon doesn't appear; computer starts up from the wrong disk; PowerBook sleep indicator glows steady green

* '''Solutions''' (p. 6) — take notes; wake the computer; restart; quit open applications; make sure the computer is getting power; check the monitor connection; check external equipment; '''resolve SCSI ID conflicts (p. 10)'''; check RAM disk settings; "re-bless" the System Folder (p. 11); use the correct startup disk (p. 12); '''resolve system extension conflicts (p. 12)'''; force a restart (p. 14); '''reset the PRAM (p. 15)'''; '''make sure memory and expansion cards are installed correctly (p. 16)'''; '''replace the computer's backup battery (p. 16)'''; '''test and repair the hard disk (p. 16)'''; reinstall system software (p. 17)

* '''2. Problems Using Your Computer''' (p. 19) — applications, documents and memory (19); '''hard disks, CDs and other storage media (25)'''; printing (32); performance (33); networks and file sharing (36); sound and video (39)

* '''3. Starting Up From a CD or Floppy Disk''' (p. 41)

== What it settles ==

'''Apple's own symptom-to-cause routing for the start-up icons.''' The booklet maps each start-up symptom to an ordered list of solutions with page references:

{| class="wikitable styled-table"

|-

! Symptom !! Apple's ordered checks

|-

| '''Disk icon with a blinking question mark''' || external equipment connected and on → SCSI ID conflicts → "re-bless" the System Folder → extension conflicts → reset PRAM → test and repair the hard disk → reinstall system software

|-

| '''Disk icon with an X''' || using the correct disk as a startup disk

|-

| '''"Sad Macintosh" icon''' || external equipment connected and on → correct startup disk → (and onward through the same list)

|-

| '''Computer won't start up at all''' || getting power → monitor connected and adjusted → increase memory for system software → force restart → memory and expansion cards seated → '''replace the backup battery'''

|-

| '''Unusual sound at start-up''' || external equipment → '''memory and expansion cards installed correctly'''

|-

| '''Freezes while extension icons appear''' || take notes → external equipment → extension conflicts → test and repair the hard disk → reinstall

|}

Two things in that list are hardware checks that get skipped: '''reseating memory and expansion cards''' as the response to an unusual start-up sound, and '''replacing the backup battery''' as a cause of a machine that will not start at all. Both appear in Apple's own list, at owner level, before any service call.

'''Note what Apple does not say here.''' The booklet names no battery voltage, no battery part number and no replace-below threshold — for those, see [[Battery Explosion, Capacitor or Corrosion Damage]] and the machine's own Service Source volume. It also gives no chime, beep or Sad Mac code table; for the compact Macintosh codes see [[Sad Mac Error Codes]].

== What it does not contain ==

No schematic, no parts list, no component values, no disassembly and no measurement. It is a software and configuration troubleshooting booklet.
