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)
