The SRM recognized the 192MB of RAM but the RAM was not usable.
I Also did a "test mem" and the test failed after about 20 seconds giving
a lot of errors. I Removed the 16MB simms and I replaced them with 4 8MB
simms and left the 4 32MB simms inside and now the new total 160MB of RAM
works very fine.
