Note to those who thought this was OS related, this deals with the SC
Platform for the new SunFire mid-range servers (3800, 4800, 6800). This
level of operation is like 2 levels before the OS loads.
I found the answer, thought I'd share if anyone was curious.
This is for the platform controler (SC0) on a SunFire 3800
1. Reboot
2. During the first 30 seconds after boot, hit Control+A, this will get you
a RTOS promt
3. When you get the --> prompt, get the current boot settings..
    --> getBootFlags()
            Save this hex number for later
4. Change the boot settings to disable autoboot
    --> setBootFlags(0x10)
5. reboot by pressing Control+X
Now for the fun stuff
6. Reset the SC Platform password
    --> kernelTimeSlice 5
    --> javaConfig
    --> javaClassPathSet "/sc/flash/lib/scapp.jar:/sc/flash/lib/jdmkrt.jar"
    --> javaLoadLibraryPathSet "/sc/flash"
    --> java "-Djava.compiler=NONE -Dline.separator=\r\n
sun.serengeti.cli.Password"
The last command will produce output of "Cleared SC Platform Password..."
7. restore boot flags with number saved from step 3
    --> setBootFlags(0xc)
8. Reboot and set a new password
