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_nvread
tpm_nvread(8) tpm_nvread(8)
NAME
tpm_nvread
SYNOPSIS
tpm_nvread [OPTIONS]
DESCRIPTION
tpm_nvread reads data from an NVRAM area and either displays them or writes them into a file. The user must provide the index of the NVRAM
area. If the user provided the number of bytes to read then this will be the maximum number of bytes that will be read from the NVRAM area,
otherwise the whole NVRAM area will be read. Some NVRAM areas only allow read sizes of zero, i.e., NVRAM area with index 0. Optionally an
offset into the NVRAM area can be given where the reading of the data is to start. If the NVRAM area has permission bits set that require
owner or NVRAM area authentication, then the password must be provided via the 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
-z, --well-known
Use a secret of all zeros (20 bytes of zeros) as either the NVRAM area or owner secret.
-p, --password
Depending on what type of authentication is required for the NVRAM area, this must either be the NVRAM area or owner password.
A password may be directly provided for example by using '--password=password' or '-ppassword'. If no password is provided then the
program will prompt the user for the password.
-i, --index
The index of the NVRAM area. The parameter may either be a decimal number or a hexadecimal number starting with '0x'.
-s, --size
The number of bytes to read from the NVRAM area. The parameter may either be a decimal number or a hexadecimal number starting with
'0x'.
-n, --offset (optional parameter)
The offset into the NVRAM area from where to start reading. The parameter may either be a decimal number or a hexadecimal number
starting with '0x'.
-f, --filename (optional parameter)
The name of a file the read data will be written into. If no filename is given the data will be printed to stdout.
