Diagnostics
The Forth Monitor includes several diagnostic routines. These on−board tests let you
check devices such as network controller, SCSI devices, floppy disk system, memory,
clock, keyboard and audio. User−installed devices can be tested if their firmware includes
a self−test routine.
The table below lists several diagnostic routines.

Command
Description
probe−scsi Identifies devices connected to the on−board SCSI controller
probe−scsi−all [<device−path>] Performs probe−SCSI on all SCSI controllers installed in the
system below the specified device tree node. If
<device−path> is omitted, the root node is used.
test [<device−specifier>] Executes the specified device’s self−test method.
<device−specifier> may be a device path name or a device
alias.
Example:
test net − test network connection
test−all [<device−specifier>] Tests all devices that have a built−in self−test method and
that reside below the specified device tree node. If
<device−specifier> is omitted, the root node is used.
watch−clock Monitors the clock function.
watch−net Monitors network connection via primary Ethernet
probe−ide Identifies devices connected to IDE bus
probe−ide−all [<device−path>]
Performs probe−ide on all IDE buses installed in the system
below the specified device tree. If <device path> is omitted,
the root node is used.a
