## A2SERVER
|
|
|
|
If you had A2SERVER running, and you typed either `apt-get update` or
|
|
`rpi-update`, you may have received Linux kernel version 3.12 through 3.15.
|
|
These, unfortunately, include a defective AppleTalk kernel module which will
|
|
kernel panic (crash) your system on startup when A2SERVER tries to activate
|
|
AppleTalk networking.
|
|
|
|
If you have a screen or console cable attached, you will see some debugging
|
|
information that concludes with "Kernel panic." If you don't have a screen
|
|
attached, there will be no visible signs other than that you simply can't
|
|
connect from another computer on your network.
|
|
|
|
To prevent this from happening, type `a2server-setup` *before* updating the
|
|
software on your computer. If it's too late, and you need to recover from
|
|
this situation, you could [start over][1]. Or, if you want to keep your
|
|
current installation, you have a few options, depending on your setup:
|
|
|
|
|
|
_A2SERVER virtual machine, or on other non-Raspberry Pi Linux computer_
|
|
|
|
* Start up the virtual or real machine.
|
|
|
|
* On the GRUB startup screen, choose the Recovery kernel.
|
|
|
|
* At the Linux prompt, type `a2server-setup`
|
|
|
|
|
|
_A2SERVER on Raspberry Pi with screen/keyboard/mouse attached_
|
|
|
|
* Press the shift key rapidly and repeatedly while your Pi starts up. If you
|
|
have an HDMI monitor, you can stop when you see the installer screen. If you
|
|
have a composite monitor, stop after about a minute, and then press 3 (PAL,
|
|
e.g. Europe) or 4 (NTSC, e.g. North America and Japan), and you should see
|
|
the installer screen.
|
|
|
|
* Press E for Edit, then click the *cmdline.txt* tab.
|
|
|
|
* At the end of the line, append `single` (preceded by a space).
|
|
|
|
* Press OK to save, then ESC to reboot.
|
|
|
|
* Log in with username "pi" and password "apple2".
|
|
|
|
* At the Linux prompt, type `a2server-setup`
|
|
|
|
|
|
_A2SERVER on Raspberry Pi without screen/keyboard mouse, and a Mac_
|
|
|
|
* Remove the SD card from your Pi and insert it in your Mac.
|
|
|
|
* Look for a volume named BOOT to appear.
|
|
|
|
* Within it, open *cmdline.txt* in a text editor (the default is TextEdit).
|
|
|
|
* At the end of the line, append `single` (preceded by a space), then save it.
|
|
|
|
* Eject the SD card and put it back in your Pi, then start up your Pi.
|
|
|
|
* [Log in to your Pi](a2server_raspberrypi_login.md) and type `a2server-setup`
|
|
|
|
|
|
_A2SERVER on Raspberry Pi without screen/keyboard mouse, and a Linux computer_
|
|
|
|
* Remove the SD card from your Pi.
|
|
|
|
* On your Linux computer, type:
|
|
|
|
~~~ bash
|
|
wget ivanx.com/a2server/fix; source fix
|
|
~~~
|
|
|
|
* Follow the on-screen instructions.
|
|
|
|
* If after using the fix tool, you still can't connect from your Apple II,
|
|
[log in to your Pi][2], and type `a2server-setup`
|
|
|
|
* (Alternative approach: Follow the Mac method above, though the volume may
|
|
not appear as BOOT.)
|
|
|
|
|
|
_A2SERVER on Raspberry Pi without screen/keyboard/mouse, and a Windows
|
|
computer_
|
|
|
|
* Remove the SD card from your Pi.
|
|
|
|
* Install the [A2SERVER virtual machine](a2server_virtualbox.md) on your
|
|
Windows computer.
|
|
|
|
* Start the virtual machine, and log in with user name "user1" and
|
|
password "apple2".
|
|
|
|
* In the virtual machine window, type:
|
|
|
|
~~~ bash
|
|
wget ivanx.com/a2server/fix;source fix
|
|
~~~
|
|
|
|
* Follow the on-screen instructions.
|
|
|
|
* Type `system-shutdown` in the virtual machine window.
|
|
|
|
* Quit VirtualBox.
|
|
|
|
* If after using the fix tool, you still can't connect from your Apple
|
|
II, [Log in to your Pi](a2server_raspberrypi_login.md) and type
|
|
`a2server-setup`
