A500 and Baseboard 4mb. not seeing all ram [SOLVED]

[cypher007]

i have an A500 rev 5 with a baseboard 4mb fully populated in the trapdoor and 512k onboard.

back in the day i had to fit a 8372A to get 1mb chip and i remember having to bend one pin up on that. i also had to run the wire from the Gary adaptor to the middle pad 2 of JP2 and cut the trace between 2-3.

now reading the manual again after 30 years it seems i should have linked pad 1-2 as well?

is this why when i run avail, after running cram, i see 1mb chip and 3mb fast? i would have thought it should read 1mb chip and 3.5mb fast?

its as if its not seeing the 512k chip onboard or maybe the 512k chip on the card?

solved.

needed to read the rest of the manual. i had the jumper set correctly what i needed to do was run cram with the command contig not fatter.

now have 1mb chip and 3.5mb fast.
