Re: My *beepin* 486 (was Re: tlug: The meeting...)

Jonathan-san;

Thanks for a decent bit of detective work :-)  I had found the page on the m/b diagram,
but not on the m/b specifications - couldn't find it the first time through.

Yes, it looks to be the memory to be my problem (I hope); the memory I used came out of
an intel TC430HX socket7 m/b, which would be EDO mem.  And just to confirm, the beeps on
bootup were 1 short followed by 2 sets of 3 short (1-3-3).

Any 486 memory gurus out there?  I couldn't find any reference to parity/non-parity.  Is
this an issue with FPM ram, or is there only one variety. Also, I know that *some* 486
boards will accept single memory modules (as opposed to adding modules in pairs); is
this true of all 486 boards?  I guess I'm looking for a total of 32meg; 2 16meg modules
is probably the safest.

Thanks again!

Sean.
