- To end all discussion, here is a description of the Macintosh
- startup sounds:
-
- 1) Power on.
- If the Mac digital logic board is properly connected, and the
- speaker is connected, too, the well-known power-on chord plays.
-
- 2) Internal system tests.
- After the initial chord played completely, the Mac tests all of its
- components (i.e. RAM, ROM, I/O ports, disks, buses and so on). If any of
- these tests _fail_, for each of the tests passed (including the test which
- failed), a tone is emitted.
-
- 3) After all hardware tests, the disk icon appears, and the Mac searches for
- the first drive containing the system folder. If no such folder is found,
- the blinking disk icon remains.
-
- Thus, the four-tone sequence tells you the fourth _hardware_ test failed. To
- put it short: This Mac is broken. Have a dealer reapair it.
- Before doing so, check your SCSI cabling. This is the only source of
- hardware-failures you can fix yourself.
