Hello,
I have a VAX 4000-100A with possibly faulty firmware, version KA52
V1.3 VMB 2.15.
I would try to upgrade the firmware, I found on Maintenance Documents
a paragraph describing
how to upgrade it, having a ROM image file or a bootable tape.
Anybody has some of it?
Thanks
Andrea

I may be able to dump the ROM if it is of any use to you, assuming I
can find
what address it is at in memory.

VAX ROMs are usually located at address 20040000. One way of dumping it
is to use the examine command from the console (although it takes a while).

This will output a list of longwords which can then be converted to a
binary file. Alternatively you could read it from the OS by mapping to
the physical pages. Don't know if the ROM is 256k; that's just a guess
as they do vary.
