7.3 Hardware Dependencies
Note: To make use of the features described in this section proceed
as follows:
• copy the OpenBoot image from the boot PROM which is a read-only
device to the boot flash EPROM (see section 7.3.1 “Copying the
OpenBoot Image from Boot PROM to Boot Flash EPROM” on
page 116)
• and use the boot flash EPROM for booting (see SW6-2).
7.3.1 Copying the OpenBoot Image from Boot PROM to Boot Flash EPROM
The following section describes how to copy the OpenBoot image from
the boot PROM into the boot flash EPROM. The copy is done via some
memory space and makes use of the ability to switch between the boot
PROM and boot flash EPROM. There are 2 versions of this procedure.
The first version uses the OpenBoot command
plcc2tsop
which is
available in OpenBoot versions 3.10.4 or greater whereas the second ver-
sion applies in any case.
plcc2tsop ( — ) copies the contents of the boot PROM into the boot flash EPROM. A
sample dialog is given below. To be successful, the boot flash write pro-
tection has to be disabled by setting SW4-3 to
ON
.

ok plcc2tsop
COPY OBP from PLCC to TSOP boot flash
