Macintosh Image Check

If you see:

--- WARNING: This image does not appear to be a valid Macintosh Device image.

In your log you'll end up here - welcome!

This is due to your BlueSCSI being in in Apple Quirks mode (Default) - If you're running on a non Macintosh machine you can do a few things.

  1. Set your System=Generic in your bluescsi.ini file.
  2. Disable all configuration checks (Apple or otherwise) by DisableConfigHook=1 in your bluescsi.ini file.
  3. Ignore the message, they are harmless and just a note to help you. They do nothing to your image.

Macintosh

There are two types of images you'll come across on the internet. Device and Volume. Only Device images will work with a BlueSCSI.

Device Image

Device images are byte for byte what is on a real SCSI hard drive. They contain a Partition Map, SCSI Driver, and one or many HFS partitions.

These images are what you use in a BlueSCSI.

You can find pre-made blanks & pre-made installed on the Usage page - or use Disk Jockey to create them.

They will work in emulators such as Basilisk II, MAME, and Sheep Shaver. Note: Just because an image boots in a supported emulator does not mean it's a Device image.

Volume Image

Volume images are ONLY the HFS part of the drive. They do not contain a SCSI driver (so will not work on a real machine) nor partition map.

These are usually found when using Mini vMac and other emulators since they do not emulate SCSI.

Switching between the two.

  1. Drag the image onto Disk Jockey.
  2. Convert it!

Macintosh SCSI Drivers

Recommended

Apple Driver 4.3 are compatible with almost every Mac. Formatting can take hours so grab one of our pre-formatted blanks from the Usage page instead or use Disk Jockey

NOTE: If you are making an image to share with many different systems, Apple Driver 4.3 is the best choice.

FWB is the best choice for images used in PowerMacs - Usually provide the fastest speeds.

Drive Setup on System 7.1+ is recommended for '030 machines and above. Drive Setup drivers will not work on a Macintosh Plus.

Avoid

LIDO is not recommended as it affects performance and is incompatible with the Macintosh Plus. Disk Jockey can replace the driver if LIDO is detected.

LaCie Silverlining does work but doesn't seem to improve performance or compatibility over LIDO.

Tips

It is best to have uniform SCSI drivers on a system, especially older machines. Do not mix and match.
