Waitaminute...so the disk image that you generated by reading a
bootable 7.3 CD differs from the HPE-distributed 7.3 file? Does the
latter not contain standalone backup at the beginning, etc?
When writing the CD, you don't need to worry about
the 512 vs 2048 byte
block problem.? That's only for the CD drive hooked to the VAX.? An
RRD42 has the appropriate block size.? The only thing I don't know is if
an RRD42 is too early of a drive to handle a CD-R or not.
I've used CD-Rs in RRD42s. It helps to burn them at no faster than 8x.
Yes, I know, the speed at which you burn it shouldn't make any
difference. But I was beating my head against a wall trying to boot a
DECstation from a CD-R disk, three tries, and a friend told me to try
the burn again but restrict the speed to 8x. I was skeptical, but I
tried it, and it worked, and I've had no issues since.
