Digital Data Memory on Vax 750/Unix

[Ken Mandelberg]

We bought some Vax 750 1 Meg boards from Digital Data
Systems. For some reason when first powered up 4.2-3 BSD
doesn't see them. The company said it wasn't a problem on
VMS, and in fact if we run the DEC memory diagnostic before
booting, Unix sees them until the next power failure. 

The company said that it had something to do with the fact
they used 256K parts, and the initial pattern that comes
up on the board is different.

Does anyone have an easy solution to avoid the manual intervention
needed on a cold boot. I guess I could hack up the standard boot
program to use some other criteria for finding memory, but it
would be nice not to have to.
