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
|
