+The purpose of the Apple %%//%%e boot blocks are to install ProDOS in memory, initialize AppleTalk, and allow the user to logon to a file server.  Ultimately, the end result is that the system achieves a diskless startup. The IIgs boot blocks are similar, but include a first-stage boot loader that loads a second stage (which is what we are concerned with) that includes the second stage code itself ("Fizzy") as well as several embedded files for setting up AppleTalk higher-level protocols and selectively booting ProDOS 8 or GS/OS.
-These AppleShare Apple %%//%%e boot blocks use the latest version of the logon program and are available with ProDOS 2.0.3 (the last official release from Apple) or ProDOS 2.4.1 by John Brooks.

+ProDOS 2.4.1 has been patched to work around bugs in Bitsy Bye related to the Apple %%//%%e Card for Macintosh LC.  Note that [[http://www.callapple.org/vintage-apple-computers/apple-ii/announcing-prodos-2-4-2-for-all-apple-ii-computers/|ProDOS 2.4.2]] includes these fixes.

+**Apple IIgs** //experimental//
+Normally, the Apple IIgs reads the Boot OS (ProDOS 8 or GS/OS) selection from the battery RAM (BRAM).  The following boot blocks have been modified to allow overriding the BRAM selection by two methods: Press ''8'' or ''G'' before the "Starting Up Over the Network" message appears to select ProDOS 8 or GS/OS respectively, or modify the ''ProDOS16 Image'' file at $0204 to have 0 for firmware decides (default), 1 for GS/OS, and 2 for ProDOS 8.

+    * This will allow booting to ProDOS 8 without having the machine freeze.
+    * Geoff's ''ATALKIRQ'' PIF is not required and should not be installed if this image is used.
+    * For more information, see {{http://appleii.ivanx.com/a2server/scripts/a2server-5-netboot.txt|here}}.
+Note that ProDOS 2.4.x seems to have trouble being part of the GS/OS boot blocks and crashes to the monitor.
