Addendum for S1571S
The three sections which follow should replace the corresponding
sections on pages 10, 12, and 45 respectively of the S1571S User’s
Manual, Revision 1.0. The changes made to these three pages are
minor.
w
On page 10, the P54C rows of the VID3 column have been
corrected from OFF to ON.
To reprogram the System BIOS, you must first do the following:
1. Check jumper JP23 (default pins 1 and 2).
The S1571 uses a 5V Flash EPROM, so jumper JP23
should be left in the default postion on pins 1 and 2. This
jumper should never be moved, and on some boards has
been hardwired.
