is a bare bones uVAX-II cpu and inst very fast but I never
 thought the boot to be unusually slow unless the dianogstic
 were running.  
   RD5x drives are painfully slow, and this is especially a problem in
 the VS2000 because the integrated disk controller a) lacks DMA, and
 b) lacks the T11 chip to do local processing found in a RQDXn - the
 uVAX CPU has to do all the work.    
Wolfgang Moeller produced some patches way back when for the
uVAX/VS 2000 that would allow it to use a SCSI disk.

Never actually tried it myself (as I had RD drives available
and faster machines if I just wanted speed).

I have RD drives so I never tried it.  I also now have RZ drives and 
it would be a good time to try it.
