Immediately after sending my last post I found this reference:
"Please also notice that 256mb PC133 and 512mb PC133 are not backward
compatible with PC100 rams. [sic]
Some old laptops have onboard PC66 ram that can not be removed, although
the websites tells you that you can use PC100 rams [sic], but most of
the time the PC100 ram will not work together with the onboard ram, you
must get PC66 rams [sic] or PC100 rams [sic] that are backward
So it seems that from that info and Tomasz's advice that my most likely
bet would be one ram card is/maybe the only one changeable but it
probably only safe to consider only getting 128mb PC66 unless I find I
have two removable ram cards.
The plot thickens ... Now you can further appreciate why I was jsut
chasing someone's cast-off ram in case it doesn't work :-)
