Help with Stubborn Sun Ultra Enterprise 450
Hello everyone...yesterday i've received a Sun Ultra E450 Server Unit and when I try to boot from everything it asks me for Firmware Password.
The unit hasn't been used for 10 years...so no one doesn't yet remember the password.
Ok,I've searched on the Internet all day long finding something about resetting the NVRAM by numerous tries like:
1.Replacing the NVRAM backwards and powering up for couple of seconds.Working.It brings the ok console to me but when I start to install Solaris 7,after reset it comes again asking for password.
2.Finding another NVRAM chip.It costs 20$ plus the taxes bringing it from U.S. to Romania. (There might be an ultimate option,IF the price will be set under max. 50$)
3.I have managed to chop the NVRAM chip dismantling the internal lithium battery and coupling an CR 2032 type.It still asking for Firmware Password
4.Supposing that an init sequence containing the password requirement should be on the hard drives....i've took them all out of the bays...Guess what......Firmware Password?
What's the explanation?It was supposed to f*in loose all the data from the NVRAM after I unplug its own power source.
Right now I've started to OBP with the NVRAM chip disconnected from any of it's backup batteries.It still asks for a Firmware Password.Is there any storage chip on the Motherboard?
It there any possibility to override that sequence or do I need to buy another ST M48T59Y? (Yeah,that's that f*in NVRAM chip)
Thanks in advance to all who might have an extra idea to this Chubby Stubby Sun E450

nvram
NVRAM(4) BSD Kernel Interfaces Manual NVRAM(4) NAME
nvram -- non-volatile RAM SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file: device nvram Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): nvram_load="YES" DESCRIPTION
The nvram driver provides access to BIOS configuration NVRAM on i386 and amd64 systems. PC motherboard uses a small non-volatile memory to store BIOS settings which is usually part of its clock chip and sometimes referred as ``CMOS SRAM''. This driver exposes bytes 14 through 128 of the NVRAM, or a total of 114 bytes, at offset zero of the device file /dev/nvram. This driver is useful for cloning machines that shares the same hardware configuration and need same BIOS setting tweaks. IMPLEMENTATION NOTES
The BIOS NVRAM's bytes 16 through 31 are checksummed at byte 32. This driver does not take care for these checksums. EXAMPLES
Backup existing BIOS NVRAM to nvram.bin: dd if=/dev/nvram of=nvram.bin Restore BIOS NVRAM from nvram.bin: dd if=nvram.bin of=/dev/nvram SEE ALSO
dd(1) HISTORY
The nvram device driver first appeared in FreeBSD 6.4. AUTHORS
The nvram device driver was written by Peter Wemm. This manual page was written by Xin LI. BSD
