 Replying to [comment:3 myob]:
 > I'm running off CD, will it have saved the syslog to the BFS partition I
 have there or not?

 Only when the boot disk is writable (i.e. not a CD) the normal syslog file
 is written. When Haiku panics, the file will not contain the kernel
 debugger output, though. Nothing is written to the file before the
 syslog_daemon has been started. Even when it is running, the most recent
 output might not have been sent to it or written to the file yet. Even if
 it has been written to the file, due to caching, it might not actually
 have been written to disk and might be lost after reboot. So, usally for a
 panic during the boot process the syslog file is not helpful, even if you
 wouldn't boot off CD.

 The syslog you can display or save from within the boot loader should be
 complete however. If you don't have a FAT32 partition or USB stick at
 hand, you can at least display it there and take pictures of the last
 part. The stack trace and the output up to a few lines before entering the
 kernel debugger would be of primary interest.
