Using hard drives which are larger than 1GB

By default the X68000 allows us to use hard drive capacity only up to 1GB (1016 Mb). Trying to create a larger partition or a partition which uses data past that point will result data corruption. The solution is to use GOVERHD. This program will apply a set of patches that will enable you to use up to 2GB of hard disk space and this tutorial will show you how to create two 1GB partitions and patch them with GOVERHD. You can create more than two partitions, if necessary, but keep in mind that the starting point of last partition must not exceed the 1016 Mb barrier or otherwise the system will not be able to boot from it.

First of all download the MasterDisk V3 and boot from it. It features Format.X, Scsiformat.X and Goverhd.x which are all translated to English.

If you are using native SCSI

Type “FORMAT”, press Enter and select “SCSI Devices”

Creating the 1st partition:

  1. Select the ID of disk drive which you want to format
  2. Select “Initialize” and answer “Y”
  3. Select “Create”
  4. Select “Size” and type “1000”
  5. Select “Start” and answer “Y”
  6. Press “Escape”

Creating the 2nd partition:

  1. Select “Create”
  2. Select “Size” and type the remaining amount of free space (Partition size must not exceed 1000 Mb)
  3. Select “Start” and answer “Y”
  4. Select “End” and answer “Y”

If you are using SxSI

Type the following commands:

  • CD SXSI
  • SCSIFORMAT

Creating the 1st partition:

  1. Select the ID of disk drive which you want to format
  2. Answer “Y” to initialize the disk drive
  3. Answer “Y” to perform physical format
  4. Select “2” and type “1000”
  5. Type “32”
  6. Answer “Y” to transfer system files
  7. Press “A” to select A: drive as source drive

Creating the 2nd partition:

  1. Select “2” and type the remaining amount of free space (Partition size must not exceed 1000 Mb)
  2. Type “32”
  3. Answer “Y” to transfer system files
  4. Press “A” to select A: drive as source drive

Using GOVERHD

Reboot the system after creating the partitions, type “GOVERHD ” followed by the ID number of your hard drive and press Enter. Answer “Y” when prompted and you should see something similar to the following screens.

SCSI SxSI

Press “HELP” key right after reset to access the boot menu and select a different partition.

BOOT MENU

Keep the scene alive !
