- I have an old IBM Original 80286 AT Machine that I'm still using. The
- motherboard has two banks of ram (bank 0 and bank 1) on it with each
- bank having 18 sockets for the ram chips. Currently it has piggyback
- 128k chips in each socket. By piggyback, I mean there are two 128k chips
- one on top of the other (I guess its another but I can't see the writing
- to confirm it) with the legs actually soldiered together. That piggyback
- chip is then placed in the mb ram socket. Upon start up the POST shows
- the systems checking 512K of ram. Also the J18 jumper on the motherboard
- is set to use both banks of memory according to a computer book that
- I have. (pins 1 & 2 are shorted together)
-
- The question that I have is can this old mb memory be increased to say
- 640K or better yet 1 Meg of ram? I have done the change of increasing
- the XT motherboards to 640K by replacing the old ram chips with 256K
- ram chip in 2 of the 4 banks. But I don't know if that same thing or
- something else can be done to get increased memory on the motherboard.
-
- Any help/suggestions would be most appreciated. Thanks in advance.
