Hi all,
My first post here - Nostalgia got to me recently, so I decided to build myself a shiny new-ish 486 setup to play with
I got a PC with Shuttle HOT-419 DZ R2 mainboard with Intel DX20DPR66 CPU accompanied by 2pcs of not-identical 4MB 72pin SIMM in banks 0 and 1.
With a faster CPU being is on its way, in the meantime, I wanted to upgrade the RAM to more than 8 megs.
I got a 5pc bunch of identical non-branded 16MB double-sided 72-pin SIMM modules (don't know if they are EDO, or FPM, nice condition but unknown if working), and had high hopes, since the MB manual I found (multiple sources) say that it supports up to 64MB modules and up to 128MB total.
Needless to say, not one of the 5pcs work, the PC does not post with any of them.
I tried working on jumpers' settings, trying modes with 4 banks and with 3 banks, to no avail.
Even with same module on multiple power-ups, one time the speaker beeps (long low-pitch repeating buzz), the other time it does not, and at no time does to screen come on.
When pairing with working modules that were already there, again, no post.
Either all of the five units are dead (I doubt), or I am doing something wrong which is obscure to me, can you advise? What could be the issue?
