I am running VMS 5.5 on such a modified VS2000. In addition to
burning the new PROMS you need to place the pk2k scsi disk driver
)called PK2KDRVR.EXE") in SYS$LOADABLE_IMAGES; the prom code specifically
looks for it. This driver is restricted to 16KB transfers. Because of this,
the creator of the prom patches, Wolfgang Moeller, has offered patch kits
and DUMP.EXE in order to make them PK2K-aware, be able to autoconfigure
the SCSI and conform to the 16KB limit.

The only problem that I have is that the patch kits are available
only for 5.5-2, 6.1, 6.2, 7.1 and 7.2 . Anything other than 5.5x
is too big for my 6MB VS2000. So before I patch the other binaries I need
to upgrade my 5.5 installation to 5.5-2 .

The disk with 5.5 was originally installed in a VS4000/60 in which
I replaced the disk with a larger one and installed 7.2 on it.
This is also the machine that I used to copy the PK2KDRVR.EXE file
to the old disk.

The VS2000 is much lighter with a 3.5" SCSI disk than with the RD53,
and has lots of extra space too :-) . I was afraid that the reduced
disk power consumption would shut down the power supply (which requires
more load than the system board presents), but it worked fine.

I still have cables, keyboards and hockey-puck mice for my VS2000, but I
don't have the 1024x864 mono monitor, so I have a vt320 connected
to the printer port with a bcc08-equivalent cable that I made.
