what is Stored on BICU nvram VS controller nvram MPC 3501

[fshead]

HI
I am about to revive my "cherry mpc3501" with 500 color prints that
flaked out when i did an ADF and netwrk firmware update..thus going to the dreaded "please wait".
So i managed to buy a parts unit wth 1.1 mil and want to swap the controller box without IOB,which i will
use the original.
I plan on swapping the NVRAM on the control board but wasnt sure what would happen if I use the "parts unit BICU with its nvram.
I try not to remove too many things with fragile pins ie the bicu nvram..
any thougts?
thnx

If the parts machine is not a C3501, you could get error messages about incorrect BICU. If it is a 3501 or if it uses the same BICU according to the parts catalog, you will still get a serial number issue and all the counters will be that of the parts machine. Showing a count of 1.1M when the machine only has 500K might make for an unhappy customer.

i am confused as i thought the biggerNVRAM "controller"was the one that had serial number and meter..

Last week I replaced controller and Bicu board on a mpc2050 with a used one...
When I started up the machine for first time, it gives sc995-1 (or something).
Than you must, via sp number 5811-4, re-enter the serial number.
And it works fine now, here.
Good luck.

I believe the EEPROM on the BICU just contains serial number and maybe a few user settings? I've replaced them on a 6001 and I just had to input the serial number on first start up. The controller NVRAM contains the meter and the non default settings for SP mode.

Don't forget to swap the NV ram on both the boards...

thanks all
I was trying not to have to pull the 8 pin nvram off the BICU brd as it looks like one could bend or break a leg/pin easily.
the controller one is an idiot proof pop on popoff.
i kinda remember doing the BICU nvram on a mpc 3300 when i swapped it with a mpc2800 BICU.

thnx
it has only 500 copies color so even more unhappy customer..

If that firmware installation failed, just put the firmware SD card back in, switch the machine on and let it sit overnight. You never know, it might do the update and be perfectly happy. Failing that, both the firmware you mentioned live on the controller NVram and it would be a damn sight easier replacing just that as opposed to a complete controller box.

thanks for the rply.
i did try reloading the FW many,many times with different sd cards and even a newer FW version and nada.
i tried disconecting the adf,HD. etc etc and poped in a "tested on external docking bay" hard drive.
I have the machine sold so it puts me in a place where i just want to see ready on screen.
I might for the hell of it swap the 1.1 million adf on my "please wait" machine just to rule out an adf lock out..

i did try giving machine a 24 hour period to come up with FW screen,and nada.
I also tried a 2nd ADF and same result.
then i swapped the controller board,same result,swapped NVRAMs,same result.
So i am leaning toward BICU now.

It looks like that would be easy, doesn't it? But if you're careful it won't happen. While there are custom chip pullers for such things, all I ever used was a pair of tweakers: pry up on one side of the chip a little bit, then on the other, and repeat until the chip comes out. Then when you are ready to put a chip back in, make sure that the pins are lined up with their sockets and you can push chip in with your thumb. You might find 1.5X reading glasses helpful for small stuff like this, at least I found them useful. Also it wouldn't hurt to ground yourself once in a while while doing that. I don't know how it is where you are, but around here the code states that the screw that holds the faceplate on to an electrical outlet will be connected with earth ground. I found that worked well for grounding myself, especially in the winter when in some circumstances I became a walking talking source of static discharge.

thnx
i cant remember what model but i did snap a leg off when doing this in the past but i think my enviroment had much to do with it..in a rush,bad lighting and
not being gentle...
i still have a wrist grounding strap that i use but i am leaning towards swapping the BICU brd and if i have to change serial number then will log on supr service mode...

Well i got to swapping out BICU brd from "parts unit" and it gave me the sc 995-01 code for wrong SN" as i did not remove the bicu nvram chip.
i cldnt get into service mode because there was a software conflict"PS3 option or the sd cards from parts machine.
i wiped the zoffy files on PS3 AND accessed sup sp mode and changed the SN,it had one for BICU brd too,changed 3 in total.
powered off and pulled plug and reinstalled the original sd cards and rebooted and all looks good.
will do a process control and ck user settings etc b4 placing at account.
thnx
