[ltp] T30 owners - Memory bank problems?

[James P. K. Gilb]

Sorry for the late response.

I have the same problem with my T30.  I have re-seated both SIMMs, 
swapped sockets, booted with only one in one of the slots.  It won't 
boot with only one SIMM in the other slot, but I don't know if this is a 
"feature" (i.e. you have to have a SIMM in a specific slot).

Basically, it only reports 256 MB RAM even though I have two 256 MB SIMMs.
