One more for the VAX crowd... 4000/90a FEPROM reprogram...

[John Klos <john%ziaspace.com@localhost>]

Hi,

My VAXstation 4000/90a made a cross-country trip so that an expert could 
replace a SIMM socket with corroded pins. It came back clean and 
beautiful. However...

I put in a full 128 megs of memory. It boots showing 64 megs, but shows:

KA49-A V1.0-006-V4.0
08-00-2B-30-95-F2
64MB

DEVNBR    DEVNAM           INFO
------    --------    --------------------------
     1         NVR    OK
     2       LCSPX    ?? 001 0480
                      Highres 66Hz - 8 Plane 4Mpixel FB - V1.0
     3          DZ    OK
     4       CACHE    OK
     5         MEM    OK
                      128MB   0A,0B,0C,0D=16MB, 1E,1F,1G,1H=16MB

So I tested the memory. No problems. I took out 64, tested one bank. No 
problems. Took that one out and put in the other. No problems. Moved those 
SIMMs to the second bank. Tested with no problems. Swapped the other SIMMs 
in to that second bank and tested. No problems. So, both sets of SIMMs 
test fine in both banks.

I put back in the full 128 megs. It comes up as 128 megs. I try to boot 
and get messages like:

boot eza0 
[1232/1831]


-EZA0~
?02 EXT HLT
  PC= 00001F6D PSL= 041F0000

and

> > > show boot

BOOT = DKA0
> > > boot


%VMB-F-ERR, PC = 00001340
%VMB-I-STS, R0 = 00000908
?06 HLT INST
  PC= 0000167F PSL= 041F0000


Looking online, other people mention similar errors in conjunction with 
corrupted FEPROMs. I have a copy of COUGAR.SYS 1.4, but since I can't 
boot via MOP, I'm not sure what else to do.

Is there another way to load a fresh COUGAR.SYS in to the FEPROMs? I was 
thinking of writing a script which (slowly) issues DEPOSIT commands over 
the serial port for all 512 KB of COUGAR.SYS, but even if I get it loaded 
in to memory, how would I flash it in to the FEPROM from the chevron 
prompt? Could I manually write all zeros, then all ones, then write 
directly to the FEPROM?

Or is there another way to do this even though I can't MOP boot?

I can't wait to get this system running...

Thanks,
John
