NetBoot LC

NetBoot LC is an alternative Apple II Workstation boot program for the Apple //e Card for Macintosh LC.

The built-in Apple II Workstation functionality of the card closely mimics the combination of an Enhanced //e with a Workstation Card in all aspects except two:

1. It shares the AppleTalk node address with the host Macintosh. This is not really a problem, because most client applications don't care what the node number is.

2. It does not load the boot blocks over the network, instead they are contained within the IIe Startup application's BBLK resources. This might be a problem depending on your use cases or preferences. For reference, the Apple II boot blocks contain ProDOS and the Logon program.

The main problems I see with the “firm-coded” boot blocks are:

  • They are more difficult to update as they require use of ResEdit each time a new ProDOS is released. While this was not a problem for some 25 years, new ProDOS releases have changed that.
  • The behavior is not the same as the other combination.

It is not clear to me why Apple decided to do it differently in the //e Card. My guesses are: It adds a little bit of speed; it prevents some administrative issues where the boot blocks served over the network have not been updated to meet a requirement of the card; and perhaps the engineers of the Card knew that the next version of AppleShare Server was going to drop Apple II boot support.

In any case, after a small and successful quest to update the boot blocks to ProDOS 2.4.1 and Logon 1.5, I decided that I wanted the //e Card to boot like my other //es with Workstation Cards, and NetBoot LC is the result.

Download

Installation

  1. Download NetBoot LC to your Macintosh.
  2. Decode the Macbinary file. The resulting file will look like an application, but it is not and clicking it will do nothing.
  3. Open NetBoot LC and a *copy* of IIe Startup in ResEdit.
  4. Open the BBLK resources in the copy of IIe Startup, there should be one resource with ID 5120.
  5. Delete BBLK ID 5120.
  6. Open the BBLK resources in NetBoot LC.
  7. Copy ID 5120 from NetBoot LC to the BBLK resources in the copy of IIe Startup.
  8. Quit ResEdit, save the copy of IIe Startup on your way out.

At this point launching IIe Startup and booting over AppleTalk should work as described above.
