rawrite under DOS should yield exactly the same results as dd under
[Be sure to use relatively new, high-quality diskettes!]

I think I faced a similar problem. What I did was to insert the floppy
wait for 20-30 seconds until the drive spins up for a few seconds and
stops. [The drive light does not come on--I verified the disk movement
gently touching the diskette while in the drive. I assume that the disk
presence and maybe format are briefly checked by the boot monitor.]

Once the boot monitor checks the disk, it can be accessed. Just boot as
normally would. YMMV!

I also have an RX23.

I typed the boot commands directly on the VS console. [I have a monitor
and kbd.]
However, the commands could just as easily be sent from a serial

The command:

	b/3 dua2

translates as follows:

b = boot
/3 = prompt for user input (i.e. don't autoboot)
dua2 = the floppy device, found by typing 'show device' on the console

This was answered in another post.

Good luck. I hope this helped a bit.
