SIXPAKPREMIUM/EGA USER'S MANUAL
Problem: The SixPakPremium/EGA's default configuration,
as shown on pages 2-3 and A-3 of the user's
manual (part number 000424-001A) is incorrect.
The default should set the board to backfill
384K with a 256K starting address. The default
as shown in the manual sets backfill to 256K,
not the necessary 384K.
Symptoms: With the switches set as shown in the manual,
an XT style machine would boot, but it will
only have 512K of conventional memory. A PC
will fail POST with an 8055-201 error message.
Solution: Pages 2-3 and A-3 show
SW2 positions: 7-off
8-on
SW2 positions should be: 7-on
8-off
