[Duo2400] Re: STILL NEED TECH SUPPORT HELP!!!!! PLEASE READ THIS!!! (memory problem)

[Paul Miller]

Ralph,

Thanks for the reply.  I'm running 9.0.4.  I had a
96mb memory module that worked until one day when I
thought I had therma shutdown and consequently a
reboot "freeze" at the happy mac when I thout it was
checking the memory.  The 64mb memory card was from
DMS..unfortunately I don't have any access to another
2400 to check.

I'n desparation I may try to reload OS 9 from an
external scsi disk but won't I still have a memory
error?  This wouldn't be the cpu causing the problm
would it?

Paul
