[rescue] looking for MVME162 ROM Images

Hi Folks

I have an MVME162-212 board in a MVME Chassis (Cell-Master) that I am trying to bring up and run some form of BSD on. Unfortunately it doesn't seem to have the original Motorola boot roms with 162Bug and on boot it puts out what looks like garbage (have been through from 1200/2400/4800/9600/14400/19200/38400/57600 baud) and suspect it is trying to talk to special software running on a PC.

Does anyone know where I might be able to find motorola 162 roms so I can then burn some?

Also anyone know of a good reference for the RJ45 Serial port so I can double check the cable I have assembled is correct.

Cheers and thanks in advance

Richard

I have no direct experience with this hardware, but bitsavers has some
documentation and firmware images it seems:

Hi Andrew

Fantastic and thank you. I had looked at bitsavers but had missed the "firmware" folder down the bottom there....my excuse was is that it was past midnight....off to erase a couple of eproms :-)

Regards

Richard

Hi Richard,

It's not very likely, but the garbage on serial console could be caused by
EPROM size jumper. Bear in mind that 162-212 comes with no SCSI chip, LC
cpu and 4MB so running BSD is not possible.
Theoretically you can add VME memory board and replace the 68LC040 with 68040.
This will allow you to netboot OpenBSD or NetBSD.

The LC040 should be able to run a soft float NetBSD (its done for some
mac68k models).

4MB *should* just about boot, though you will need swap (and patience
:) to do anything. If you're just looking to use it as a general
hardware/SCSI test then it should be enough...

Hi All

So thanks for all the replies.

I have burnt a new ROM in a 27C080, modified the jumpers and made a custom cable as per the information at the back of one of the manuals. Success!

I know have the board booting to 162-Bug> prompt.

I do however get the following WARNINGS
- ROM Checksum Error, Expected......
- Configuration Data Failure (Invoke 'ENV' Command)
- Board Configuration Data Failure

Not sure if the ROM Checksum error is worth exploring further at this point...maybe when I run ENV and update config data that will go away. I am hypothesizing that the checksum is stored in flash and what it is comparing isn't the same anymore.

The other two errors make sense given what has happened to the board (been powered off for a very long time, might have a flat timekeeper, had the ROM replaced, had 3 other boards removed from the chasis)

now the journey begins to get a bootable OS installed and maybe find a few more parts like a 68040 to replace the LC, 16M mezzanine board, SCSI or CF Card, memory board etc...

I would be interested if anyone out there is still run an MVME chassis and what they run on it....down stream I was thinking of getting an i860 quad card or some other esoteric boards....

Cheers and thanks again for all the insights.

Regards

Richard

Hi Richard,

" - ROM Checksum Error, Expected......" - this should not happen. I haven't
seen it often.
The checksum is stored in the rom/flash itself. Since you are booting
directly from ROM you could try to play with pflash and cs commands and try
to reprogram the flash memory and boot from it. But if the necessary 162bug
commands execute well, leave it this way.

" - Board Configuration Data Failure" and " - Configuration Data Failure
(Invoke 'ENV' Command) " - the nvram is dead, use cnfg;m at bug prompt to
add the correct values and then execute env;d

I strongly recommend to replace the LC with 68040. Without SCSI board
(MVME327 or MVME328-confirmed and working with OpenBSD) you have to netboot
the os. I suggest you to start with OpenBSD.

Regards,
Plamen

Hi:
I don't know the specifics of the cpu board you are using but some general
comments that may help.
I think the format for the ROMs is the Mot hex format which, IRC, has the
check some stored in the last locations of the ROM file.
Also, the EPROM programmer should have computed a CS. Some smarter
programmers (i.e. the Data I/O) could be configured to read and compare the
CS from the downloaded ROM file. If true in your case, you could compare
the two.
In addition, perhaps you could compare the CS computed by your programmer
to what the system board thinks it is.
I'd also try burning a new set of EPROMS.

How is the system board computing the CS comparison?
good luck.

"Check some"? I'm gonna guess speech recognition. ;)

If you'd like to replace the 68LC040 with a real 68040 I have two
68040's I have no use for. One is 25Mhz, one is 40Mhz.
