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.

-If the system is set to boot ProDOS 8 it uses the ProDOS contained within the boot blocks.
+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.
