Just checked and the prevailing thought is that if you do not have a separate disk as a raw partition this won't work. As also mentioned in other responses the DEMO version will install up to 1GB database space. But if you want to try the standard R4 TNT version then this is what I did for 3.0.1.

1. Run the install shield setup to get the software moved and the recond and gateway system processes installed. (R4 probably has new steps in this part)

2. Figure out how many VPROCs you want.

3. Use the NT Disk Administrator to set up the raw partitions for your VPROCs. 1 per or 2 per VPROC (or more if you have the space). Do this even if you are using RAID (1 or 5). Make them the same size and make sure you do NOT have drive assignment (e.g. F: G: etc.). If you've never used the NT Disk Administrator it may take you a couple of tries. But it's all there in menu picks - check the help if you get lost.

4. There is a utility called partitioninfo (open a Teradata command window and type it in) that they included in the releases I got. It pops up a messagebox that has the Device description, the number of sectors and some other stuff that doesn't matter. Write down these two pieces of info for every raw partition that you are going to use.

5. Edit a file called vconfig.txt

<>

the one attached above is from home desktop machine, with 2 vprcos. The lines you need to edit are:

     PDISK
     #CL_ID  VDISKID  SECTORS     ARRAY_TYPE       REDUNDANCY  PARTITION_NAME
        0      0      5301450     NONE             RM0         \Device\Harddisk0\Partition2
        0      1      5301450     NONE             RM0         \Device\Harddisk0\Partition3

     VPROC
     #CL_ID   VPROCID   TYPE   MOVABLE   NODE_ID   HGID  VDISKID
        0         0       1        Y      001-01    -1      0
        0         1       1        Y      001-01    -1      1
        0      1023       2        N      001-01     1     -1
        0       512       3        N      001-01     1     -1

put the partition name in the partition_name column and the sectors in the sectors column. ONE GOTCHA - the sectors number must be the lowest number of all partitions. If you are using RAID5 then you can change the Redundancy column to RM5 - there are some valid values for ARRAY_TYPE - but I can't recall what they are - I don't think it matters (The TNTdemo shows a vconfig.txt file with RM0). Identify the VDISKID. You can assign multiple partitions to a single VDISK.

Add lines to the VPROC section for each VPROC.

The VCONFIG.TXT file belongs in ??? in R4 - For the TNTdemo the path is Program Files/NCR/TDAT/tdconfig. You should check to see if that directory gets created by the install wizard.

6. Use the Teradata command prompt window to run the vconfig utiltiy.

7. Restart your machine.

8. Open a dbwindow and run sysinit. do NOT pick the international hash option when it comes up.

9. once logons are enabled, run DIP.
