The previously quoted comments of mine were in regard the the version 1.0 Sirius card which had no jumpers since it could 'self detect' SIMMs in its slots. It is version 1.0 which works better if you have a SIMM in the 8th slot even if it is being used on a ROM 3. As for your version 2.0 card and the jumpers.... The jumpers are used to configure the card so it knows how many SIMMs you have installed and whether they are 256KB or 1MB SIMMs. You can have the following set-ups according to the docs (1 sheet of paper!): (assumes 1 MB SIMMs unless explicitly noted) 1 Meg: 7.5C o=o o D4 o o=o D6 1024K o=o o 256K L o o=o CRow0 H o o=o CRow1 2 Meg: 7.5C o=o o D4 o o=o D6 1024K o=o o 256K L o o=o CRow0 H o=o o CRow1 4 Meg: 7.5C o=o o D4 o o=o D6 1024K o=o o 256K L o o=o CRow0 H o o=o CRow1 8 Meg: 7.5C o o=o D4 o o=o D6 1024K o=o o 256K L o o=o CRow0 H o o=o CRow1 1 Meg (256K SIMMs): 7.5C o=o o D4 o=o o D6 1024K o o=o 256K L o o=o CRow0 H o o=o CRow1 2 Meg (256K SIMMs): 7.5C o o=o D4 o=o o D6 1024K o o=o 256K L o o=o CRow0 H o o=o CRow1 I hope this is helpful.
