additional EDO memory hangs operating system at startup

Archived from groups: comp.sys.laptops,comp.laptops (More info?)

Get ahold of a program called Memtest (Google it). You can make a
boot disk and boot into it, then run Memtest on your system. It will
tell you if your memory first of all is any good or not - just let it
run for a bit. If it doesn't report memory problems, then consider
Windows...

: 64MB onboard + two 64MB modules = 192MB

: There is not an example of on-board 32 mixed with 64 module(s).
