Yes. It most likely won't work. At least, it doesn't accordingly
to my experience.

At work, I tried to plug EDO RAM into many older machines (around 20),
all running different motherboards but with AWARD BIOS and CPUs
ranging from P60 to P120, sometimes intentionally, just to see if
it would work and sometimes by a mistake, e.g. when a user brings
or buys memory himself. It simply never worked: either BIOS reported
checksum error or the system beeped. I don't know if it is just the
particular motherboards that do not support EDO RAM (I was unable to
find any manuals nor I had time to look it up on the net) or something
else. I tried installing the SIMMS in different sequence, mixed/non-
mixed, with varying BIOS memory timing settings, no luck. Very
unfortunately, because we also have lots of EDO RAM and almost no
conventional RAM and would like to perform a memory upgrades many
of those older Pentium boxes purchased 2 - 4 years ago and having
only 8 - 25 MB of memory. The same EDO SIMMS work excellent in
PPro and AMD-K6 boxes with newer motherboards purchased last year,
without any fiddling.

Their reasoning to refuse to do so may be related to the fact
that many old 486 boards use 30 pins SIMMS and EDO RAM is made
only in 70 pins modules. Not that I saw anyone in Vancouver
Computers advertising 30 pins EDO RAM anyways.
