Stern EPROM U9 Bootflash v3.1

Software revision 3.1 of the 8mbit BOOTFLASH EPROM in socket U9 used on all late model Stern S.A.M. pinball machine computer systems.

This software revision is necessary to enable the Stern SAM pinball system to read all current types of USB flash drives or thumb drives for game software updates.

SOFTWARE REVISION HISTORY

VERSION 3.1 - RELEASED JANUARY 28, 2008 - IMAGE CHECKSUM: 4CF6

Changes since version 2.30:

INCORPORATES SYSTEM CHANGES UP TO AND INCLUDING SYS. 1.39. THESE INCLUDE:
During USB update, if a USB memory stick was inserted that had no files on it, then the update code would crash the game. This has been corrected.

When booting from EPROM, the 'USB / BACKUP' test menu entry is no longer available. Backup of game code may still be performed from the USB menu when booting game code from FLASH.

INCORPORATES SYSTEM CHANGES UP TO AND INCLUDING SYS. 1.39.
THESE INCLUDE: Boot from EPROM now honors all factory defaults, as if factory reset had been performed for the current dip switch settings each time the game is booted from EPROM.

Fixed a problem with changing the dip switches. When the dip switches were changed and the game was rebooted, the system would not install the proper adjustment override values associated with the new dip switch settings. This has been corrected.

Updating the game code no longer resets the Tournament data, if possible.
