Original question follows ...
> Hello everyone,
>
> I need your incedible expertise to help me diagnose a problem.
>
> Here's a description:
>
> Machine:
> --------
>
> Sparc 4, w/ 32MB memory, ROM rev 2.24, Os=SunOS 5.4
>
> Problem:
> --------
>
> At boot-up, I get an error message, even before the banner.
>
> Incorrect Configuration Checksum
> Setting NVRAM parameters to default values
> Setting Diag-switch? NVRAM parameter to true
>
> then it probe the SCSI bus and I get the Ok> prompt. It doesn't go along with
> the boot process.
>
> I did a couple of printenv to try to find the problem. I noticed that I get a
> weird value in security-#badlogins. Here's a extract of the printenv":
>
> security-mode none
> security-password
> security-#badlogins 205287023
> oem-logo no defau... ( note it's not <no default>)
> oem-logo? false
>
> I figured security-#badlogins and oem-logo had incorrect values so I tried to
> change them. To tests with security-#badlogins:
>
> OK> setenv security-#badlogins 0
> security-#badlogins=205287023Data Access Exception
>
> OK> setenv security-#badlogins 1
> security-#badlogins=205287023Memory Address not aligned
>
> It's consistant with my problem too. When I finally manage to boot the
> machine, after 3-4 retries, nobody can login the machine besides root. They
> get a "change the password" message wich I figured was related to the content
> of the EEPROM.
>
> My Diagnostic:
> --------------
>
> The PROM fried for some obscure reason and I need to get it replaced. If you
> think I'm wrong, please let me know.
>
> All input will be greatly appreciated. I *need* this machine back online.
