BSD2.11 on a 4Gb SD card for SCSI2SD

Some screen shots for my config of scsi2sd for my SD card.

The copied SD contains 4 logical disks.

  1. Disk 0 is BSD2.11 boot off ra(0,0,0)/unix
  2. Disk 1 is a "safe copy" of a minimal BSD2.11. If you screw up disk 0 you will be able to boot off ra(0,1,0)/unix and be running a recovery disk type system.
  3. Disk 2 is 800Meg "spare". This can be mounted as ra2a
  4. Disk 3 is 2Gb "spare". Never used - could be ra3a-g

When you get your scsi2sd card you NEED to set up the sizes of the volumes as shown below. You can do that by connecting the scsi2sd card via a USB port - no need for 5/12volt nor for the scsi cable to be in - and running the scsi2sd-util on windows or Unix.

NOTES:

  1. The sizes of volumes are NOT recorded on the SD, but "somewhere" on the SCSI2SD card itself. So, if you change these numbers your SD card become mince.
  2. the version of scsi2sd-util I found for linux would only run on a 64 bit architechure. I found source downloaded it and recompiled for 32 bit (I dont run windows not 64 bit linux).
  3. I think I read that while running the util you MUST NOT access the device viia the scsi bus.
  4. About 1 in 6 times the scsi2sd-util freezes on my system (dont know if this is my system, the 32 bit recompile etc etc). I just stop and restart the scsi2sd-util and continue. I have never had 2-in-a-row failures.

I made the copy by dd'ing the 4Gb SD into a file and dd'ing it back again to a fresh SD.
dd if=/dev/mmcblk99 of=bsd2.11 bs=102400

Once the SCSI2SD has been told the partition sizes I insert the SD card and then attatch it to the scsi controller on the PDP.

On my UC07 controller I did the RDF (or FRD or whatever it is called) that reads in the disk partitioning info and puts it on the UC07 NVRAM. I will put the link in here later to that process. it is well documented elsewhere.

Sizes below, and booting off the SD.

nonepartition 0
nonepartition 1
nonepartition 2
nonepartition 3
noneOn-Board-Boot
nonebooting
nonebooted

There could be some files on ra2a that are copies of files from TK50 tapes. These came off 2nd hard TKs that I bought that were not wiped. I would prefer if you dont distribute that data. It is financial and I dont know the sensitivity of it.
