How does one determine what is causing kernel panic on attempted boot?

본문:

== Unit Description ==

Serial Number: W87130ZKVGN

Type: iMac "Core 2 Duo" 2.16 24-Inch (T7400)

Intro.: September 6, 2006

Disc.: August 7, 2007

Order: MA456LL

Model: A1200 (EMC 2111)

Family: Late 2006 - 24"

ID: iMac6,1

RAM: 2 GB

VRAM: 128 MB

Storage: 250 GB (7200 RPM)

Optical: 8X DL "SuperDrive"

== Problem Description ==

All attempts to boot the system from any media result in a kernel panic.

== What has been tried ==

*   Checked that it makes all the right "chime" noise on startup, before the apple and spinning gear.

*  Booted into single user mode and was able to access hard drive file system without errors. Was able to mount the HD as read/write and run standard repair/diagnostic cmds from the command line. Also ensured permissions were correctly set. Suspect the hard drive is actually OK, but still could be corruption of O/S boot files. Not sure if this would cause kernel panic when booted from CD with HD still attached.

*   Holding down option key on startup works OK. Shows the partitions on the hard disk and other O/S boots available on recovery partition, USB or DVD. It will try to boot off selected item, but fails with kernel panic.

*  Holding down shift key on startup shows the progress bar and completes that phase, but kernel panics prior to displaying menu.

*  Holding down D key on startup works as previously noted. Extended diagnostics show no errors.

*  Holding down command V (verbose mode) works to the extent of showing boot process, but eventually kernel panics.

*  Resetting SMC and PRAM doesn't help.

*  Prior to this the unit didn't give any indication that any hardware was failing or software was corrupt.

*  Disassembled and inspected unit for any obvious loose connections or damaged components. Found none.

*  Pulled the hard-drive cable and verified that I got a file folder with a flashing "?" on startup.

*  Tried booting from DVD with HD cable disconnected. Still causes kernel panic.

*  Swapped various amounts of RAM in and out, plus tried running on just one of the two slots without any success.

== Supplemental Info ==

Originally suspected just a bad hard drive, because of only getting as far as white screen. Subsequent testing with the original install disk indicated that the actual issue was a kernel panic, since a text message to restart the unit was displayed.
