Warning: We strongly recommend that you backup all of your files on your D8B's hard drive BEFORE upgrading to version 5.1!!! Please read the Release Notes for D8B v5.1 before continuing with the installation.

Note: Unless you have registered and unlocked your copy of D8B v5.1 software, it will run in demo mode for 7 minutes, after which you will be required to re-boot the system. In demo mode, you cannot create, open or save sessions. You can safely re-install D8B OS version 3.0 if you choose.

Follow these steps if you are downloading onto a Mac OS™ computer:

1) Download the self-extracting file: d8b_v5_1_B445_Mac.hqx (4.3 MB)

2) To expand the HQX file, you'll need Stuffit Expander™ (http://www.aladdinsys.com). If Stuffit Expander does not launch automatically at the completion of the download, then drag the HQX file onto the Stuffit Expander™ icon. Stuffit Expander™ creates a file called "d8b v5_1 B445 Mac.sea", and a folder titled "d8b v5_1 B445 Mac". Drag the SEA file to the trash can.

3) Launch Apple's Disk Copy utility (you may need to download the Disk Copy utility from http://www.apple.com. or check the system installations disks that came with your system).

4) Label one double sided, high density 1.44MB freshly PC formatted floppy disk as "Disk 1", a second PC formatted floppy as "Disk 2", and a third PC formatted floppy as "Disk 3".

5) Depending on your version of Disk Copy, either click on the "Load Image File..." button or choose "Make a Floppy" from the Utilities menu.

6) Locate the image folder labeled "d8b v5_1_B445 Mac" that was extracted onto your hard drive, select the "d8b v5_1 B445 d1.img" file, and click "Choose".

7) Insert Disk 1 into the floppy drive when prompted. With older versions of Disk Copy you may need to click on the "Make a copy" button first.

8) Disk Copy will eject the floppy when it has finished making the image. Remove Disk 1, and repeat steps 5 through 7, using "d8b v5_1 B445 d2.img" to create Disk 2.

9) Disk Copy will eject the floppy when it has finished making the image. Remove Disk 2, and repeat steps 5 through 7, using "d8b v5_1 B445 d3.img" to create Disk 3.

10) With the D8B powered off, insert installation Disk 1 into the D8B floppy drive, and power up the D8B.

11) The D8B will boot into the installer program automatically. Follow the prompts on the LCD screen.

12) Insert Disk 2 into the floppy drive when prompted, and select "Continue".

13) Insert Disk 3 into the floppy drive when prompted, and select "Continue".

14) When the D8B has completed reading all three installer disks, it will ask you if you want to install D8B version 5.1 build 445. Press "OK" to finish the installation, or "Cancel" to cancel the installation without writing any files to disk.

15) When the installation is complete, remove Disk 3 from the floppy drive and power cycle the D8B.

**Note to Macintosh USB Floppy drive users:

Apple's Disk Copy program will not work using the above method with a USB floppy drive because the menu option "Make a Floppy..." will not be available. You must use Aladdin Systems' ShrinkWrap program available for purchase and trial download from http://www.aladdinsys.com/shrinkwrap/index.html. Once you have ShrinkWrap installed substitute these steps for steps 3-9 in the above directions.

3) Launch ShrinkWrap.

4) Label one double sided, high density 1.44MB freshly PC formatted floppy disk as "Disk 1", a second PC formatted floppy as "Disk 2", and a third PC formatted floppy as "Disk 3".

5) Select "Write Image back to Disk..." from the Image menu (command-B).

6) Locate the image folder labeled "d8b v5_1_B445 Mac" that was extracted onto your hard drive, select the "d8b v5_1 B445 d1.img" file, and click "Select".

7) Insert Disk 1 into the floppy drive when prompted.

8) ShrinkWrap will eject the floppy when it has finished making the image. Remove Disk 1, and repeat steps 5 through 7, using "d8b v5_1 B445 d2.img" to create Disk 2, and again using "d8b v5_1 B445 d3.img" to create Disk 3.
