Detailed Sparc Info w/ Openpromfs Module for Linux
Topic: Hardware Posted:2003-02-03
Printer Friendly:

You can retrieve detailed information about your Sun box by selecting the Openprom module in the General setup area of the Linux kernel:

<M> Openprom tree appears in /proc/openprom

The module should load automatically when needed under most circumstances, but we will load it manually in this example:

srv-44 / # insmod openpromfs
Using /lib/modules/2.4.20/kernel/fs/
openpromfs/openpromfs.o

To mount the openprom filesystem:

srv-44 / # mount -t openpromfs none /proc/openprom

You can view a lot of detailed info about your Sun box:

srv-44 / # cd /proc/openprom
srv-44 openprom # ls
#size-cells	       idprom
