ProDOS 2.4.x: crashes when used to replace 2.0.3 in GS/OS Appletalk Boot Blocks. #2

Open mgcaret opened 6 years ago

mgcaret commented 6 years ago

Description

When ProDOS 2.4.x is inserted in the "ProDOS16 Image" file (replacing ProDOS 8 2.0.3), and ProDOS 8 is selected as the startup OS in the Network control panel, the system crashes immediately after ProDOS 8 is initialized.

Expected Behavior

The system should boot to ProDOS 8 successfully.

Actual Behavior

Crash to monitor after ProDOS 8 is initialized.

Possible Fix

None yet, but I will investigate further as I get time.

Steps to Reproduce

  1. Set up netatalk (or AppleShare, not tested) for Apple II startup functionality
  2. Set up a share for GS/OS
  3. Install GS/OS on the network share.
  4. Boot over the network, use the network control panel to select ProDOS 8.
  5. Verify that booting to ProDOS 8 works.
  6. Modify the ProDOS16 Image file (obtained from GS/OS disk 7 "Apple II Setup") to include ProDOS 2.4.x.
  7. Install the modified "ProDOS16 Image" file on the netatalk or AppleShare server.
  8. Attempt to boot to ProDOS 8.

Context

I was attempting to produce updated Apple IIgs network boot blocks that include ProDOS 2.4.x as I have done for the Apple II Workstation Card and Apple IIe Card for Macintosh.

Your Environment

netatalk 2.4 running on Ubuntu in a KVM virtual machine. EtherTalk bridged to LocalTalk via Shiva Neworks FastPath 5.

Stock installation of GS/OS in a share.

Hardware:

Apple IIgs ROM 3 with 4 MB RAM card installed, AppleTalk configured on printer port.

ProDOS8 version:

2.4.x.

Non-Operating System release software being used:

None running on IIgs, as above for outside environment.

To adjust the ProDOS 16 image file, the official "Make Image" tool may be used (I can transmit privately if needed) or my own p16imgtool.gz.

Suitably adjusted "ProDOS16 Image" file containing ProDOS 8 2.4.2: ProDOS16_Image.242.gz

I'm not familiar with the workstation card and netbooting. I thought Appletalk support for ProDOS 8 was done via the atinit file rather than with custom boot blocks.

Can you explain in more detail or point me to tech info?

Thanks!

This isn't the workstation card, this is regarding the Apple IIgs boot blocks for booting a GS from AppleShare (or netatalk). The IIgs can boot over the network to GS/OS or ProDOS 8 depending on the setting in the Network control panel on the IIgs. When the boot blocks are modified to use ProDOS 2.4.x (a trivial thing to do), booting to ProDOS 8 crashes to the monitor.

The GS does not use the ATINIT file to initialize 8-bit AppleTalk, it has special support built into the firmware to initialize the MLI intercept and forward it to the AppleTalk code. The call is documented in the GS/OS source code for the boot blocks.

Of note, the 8-bit machines do not use ATINIT when booting over the network, either. The LOGON program embedded in the boot blocks takes care of setting the intercept.

A possibly related issue: I am unable to boot P8 2_4_2 on a ROM3 IIgs using CFFA emulated Disk II in slot 6. It crashes to monitor repeatably. http://dreher.net/forum1/viewtopic.php?f=16&t=566&sid=1bad0e94887bc154bf85b49956af9650
