APPENDIX A

Trouble Shooting

If you can't boot

Check the switch settings (refer to chapters 1 and 2).

Check which drive is set to boot under the Partition Manager.

Is the boot partition turned ON under the Partition Manager?

Does the partition set to boot contain the necessary boot files?

Turn off the computer then see if the controller card and cables are correctly installed.

IIGS Only

Make sure the Startup Device is set to the Vulcan’s slot in the Slots option of the Control Panel.

ProDOS Can’t Find All Four Vulcan Partitions

Eight Total Drive Devices

ProDOS can access a maximum of eight drive devices. If you have more than eight drive devices under ProDOS (a RAM disk, two 3.5” disk drives, two 5.25” disk drives and four ProDOS Vulcan partitions), one of the drives will not be recognized. You’ll need to either turn off one of the Vulcan partitions or disable one of the other drive devices.

Two Drive Devices per Slot

ProDOS 8 has a limit of two drive devices per slot (except for Slot 5). For ProDOS 8 to recognize three or four active partitions, you’ll need to copy the patched version of ProDOS included on the Vulcan’s first ProDOS partition (as shipped) and on the Vulcan’s 3.5” and 5.25” ProDOS disk. Use the included program, PRODOS.PATCHER, to patch ProDOS 8 on your boot drive.

*Note: GS/OS users will need to patch P8, not PRODOS.

Run the program and enter the ProDOS pathname of the disk you want to modify.

Ex: /YOUR.DISK/SYSTEM/P8 (for GS/OS) or

/YOUR.DISK/PRODOS (for ProDOS 8 disks)
