hmmm your hardware is seem old ( Sun Workstation ) ?
maybe you should to replace or reprogramming ( if it possible ) your Nvram chip.
Quote:
The contents of the NVRAM chip can become corrupted for a variety of reasons, most commonly, failure of the embedded battery. The battery embedded in the NVRAM chip keeps the clock running when the machine is off and also maintains important system configuration information. This FAQ tells you how to reprogram your NVRAM chip and where to buy a new one, should you need to replace your current NVRAM chip. If you have one of the questions marked (Replace Chip), you'll need to purchase a new NVRAM chip. The cost is about US$20. For the other questions, as long as your machine retains its hostid and ethernet address when turned off, and the clock keeps time when the machine is turned off, reprogramming your NVRAM chip is enough.
Quote:
One question is marked (Probably Replace Chip). Usually, when the NVRAM gets corrupted in this way, this is a symptom that the battery embedded in the NVRAM chip has run out and you need to replace the chip. If the machine is relatively new, you should try reprogramming the NVRAM chip with a hostid and ethernet address using the instructions below, then do a reset at the "ok" prompt to make sure the banner looks as expected. Next turn the machine off for a couple of minutes and turn it on again. If the machine retains its hostid and ethernet address, then you probably don't need to replace the NVRAM chip.

tpm_nvdefine
tpm_nvdefine(8) tpm_nvdefine(8)
NAME
tpm_nvdefine
SYNOPSIS
tpm_nvdefine [OPTIONS]
DESCRIPTION
tpm_nvdefine defines a new NVRAM area at the given index and of given size. The user has to provide the permissions that control access to
the NVRAM area.
Owner authentication is necessary once the NVRAM area 0xFFFFFFFF has been defined. The owner password may be provided on the command line
using the owner password option.
The following options are supported:
-h, --help
Display command usage info.
-v, --version
Display command version info.
-l, --log [none|error|info|debug]
Set logging level.
-u, --unicode
Use TSS UNICODE encoding for passwords to comply with applications using TSS popup boxes
-y, --owner-well-known
Use a secret of all zeros (20 bytes of zeros) as the owner's secret.
-z, --area-well-known
Use a secret of all zeros (20 bytes of zeros) as the NVRAM area's secret.
-o, --pwdo (optional parameter)
The owner password.
A password may be directly provided for example by using '--pwdo=password' or '-opassword'. If no password is provided with this option
then the program will prompt the user for the password.
-a, --pwda (optional parameter)
The NVRAM area password.
A password may be directly provided for example by using '--pwda=password' or '-apassword'. If no password is provided with this option
then the program will prompt the user for the password.
-i, --index
The index of the NVRAM area. The parameter must either be a decimal number or a hexadecimal number starting with '0x'.
To select the NVRAM area with index 0x100, the command line parameter should be '-i 0x100' or '--index 0x100'.
-s, --size
The size of the NVRAM area. The parameter must either be a decimal number or a hexadecimal number starting with '0x'.
-p, --permissions
The access permissions associated with the NVRAM area. The parameter must either be a decimal number or a hexadecimal number staring
with '0x'. It is possible to logically 'or' numbers or strings. The following strings are supported:
AUTHREAD
Reading requires NVRAM area authorization.
AUTHWRITE
Writing requires NVRAM area authorization.
PPREAD
Reading requires physical presence.
PPWRITE
Writing requires physical presence.
OWNERREAD
Reading requires owner authorization.
OWNERWRITE
Writing requires owner authorization.
GLOBALLOCK
A write to index 0 locks the NVRAM area until the next TPM_Startup(ST_CLEAR)
READ_STCLEAR
A read with size 0 on the same index prevents further reading until the next TPM_Startup(ST_CLEAR)
WRITE_STCLEAR
A write with size 0 to the same index prevents further writing until the next TPM_Startup(ST_CLEAR)
WRITEDEFINE
A write with size 0 to the same index locks the NVRAM area permanently
WRITEALL
The value must be written in a single operation
An example of a permission parameter is:
--permissions="OWNERREAD|OWNERWRITE"
