Ontrack-Manager: uninstall

This experience report was kindly put to our disposal by Matthias Wipf.

This description relates to version 7.04 of the Ontrack-Manager of Ontrack Systems. The process may be partly different with other products.

Procedure to remove the Ontrack-Manager

  1. IMPORTANT!
    It is absolutely inevitable to make a complete backup of the hard-disk before any action is done! All data get lost when the Ontrack-Manager is being removed and have to be restored later. If an additional EIDE controller is added later, then this procedure might become avoidable (cf 3. and Conclusions)

  2. Create a bootdisk with the Ontrack Disk Manager (dm.exe)

  3. Start the Ontrack Disk Manager from drive A: dm /m /y-
    The parameter /m sets the disk manager to manual mode, which results in the availability of a few more functions. The other parameter /y- causes the disk manager not to use Dynamic Drive Overlay when installing the harddisk. The - is very important, otherwise the Ontrack-Manager will be used.

  4. Add the harddisk parameters to the CMOS
    If there is no EIDE-controller available or the BIOS doesnīt support more than 1024 cylinders, it is not possible to use more than 504 MB of disk capacity (numbers may vary, depending on the mainboard), however large the harddisk may be. But there still is the option to use the maximum of 504 MB for DOS and use the remaining disk space for Linux. Linux doesnīt make use of BIOS calls and so itīs able to use the whole harddisk.
    Prepare the harddisk for DOS: Usually people want to use the maximum of 504 MB for DOS. So add in the CMOS the user defined type 47 with the maximum number of 1024 cylinders and the remaining parameters. If you are unsure about these parameters, the Ontrack Disk Manager might provide help. Just set up 305 cylinders, 4 heads and 17 sectors/track in the CMOS. Then start the Ontrack Disk Manager as in 3 and choose the menu entry CMOS Setup. The next step is to select the harddisk and then choose Automatic CMOS Selection. In case of the values in the CMOS are not optimal a note appears, mentioning the values to be inserted. These have to be set up manually in the CMOS.
    Afterwards the harddisk can be formatted and partitioned using the Disk Manager. This can be also done using DOS fdisk and format, but the Disk Manager is more flexible and much faster when formatting is concerned. Never forget the parameter /y-, or the Ontrack Manager will be installed again.

  5. Install Linux
    Linux can be installed now using setup and YaST as usual. The Linux fdisk program recognises the free disk space and the partitions can be set up as usual.

Conclusions

I have performed all mentioned steps above with a Maxtor 7850AV (850 MB) and everything worked fine. It is most important to make a backup of the harddisk and to get a bootdisk with the Ontrack Disk Manager on it. The time needed for the backup is not neglectable and the disk space for DOS and Windows is limited to 504 MB. But one getīs rid of the Ontrack Manager, which speeds the boot process enormously and has a positive effect on access times. Generally the purchase of a EIDE controller or an appropriate BIOS has to be preferred, of course. Maybe the backup can be omitted then, as the removal of the Ontrack Manager can be performed with data loss. But unfortunately I was not able to test this.
