Usage

Hard Disk image files are placed in the root directory of a exFAT (preferred, allows larger drive images) or FAT32 formatted SD card . Use a premade or blank disk below. You can have up to 7 image files on one BlueSCSI.

Note

BlueSCSI images are also compatible with the PiSCSI and other Emulators.

Premade BlueSCSI Images

You can find a list of premade, blanks, and more under the BlueSCSI Images page.

Image Files

The naming convention is as follows (file name max 64 characters). Note you may use multiple images at a time with different SCSI ID's.

HDxy_512.hda, CDxy_2048.iso

Image Type (required):

• HD - Hard Disk
• CD - Optical
• FD - Floppy
• MO - Magneto Optical
• RE - Removable
• TP - Sequential Tape
• ZP - Zip100 Drive

x - Image SCSI ID - optional, if not provided defaults to 1. 0-7. Supports up to 7 devices at a time.

y - LUN(Logical Unit Number) - (Optional, defaults to 0, currently only supports 0)

512 - Sector size. Optional - only set if you need to change. Defaults to 512 if unsure. 256, 512, 1024, 2048, 4096, & 8192 supported.

Image Directories

Multiple images can be cycled automatically when a removable drive is ejected (CDROM, Floppy, Tape, Zip, etc)

Create a folder on the SD card named CDX where X is the SCSI ID you wish to use and CD is the type (eg: CD3) . Then copy in any number of images files into the folder.

Other examples:

• Tapes on ID 1: TP1
• Floppy Disks on ID 2: FD2

Note: If your CD is not re-inserted you may need to enable ReinsertCDOnInquiry.
You can also use the CD Changer application from the BlueSCSI Toolbox to switch CD images.

Examples

HD10_512.hda - Hard Disk at SCSI ID 1, LUN 0, sector size of 512.

HD6 - System 7 Quada 700.hda - HD at SCSI ID 6, LUN 0, and 512 sector size.

HD50_512 System 6.0.8L LC.hda - Hard Disk at SCSI ID 5, LUN 0, sector size of 512. Text between block size and .hda is ignored.

CD3 Myst.iso - CD at SCSI ID 3.

If no image files are found, the green LED on the Pico module will pulse on and off. Check the log.txt on the root of the SD card for any errors.
