Do the Q605/LC 475 boot w/o the DRAM on the MoBo?
From what trag has said about the limitations of the second SIMM in the 605 and the 630, it makes me wonder if the Mobo RAM is excised these machines might be able to address the full theoretical loadout using the four full capabilities of double banked SIMMs. It appears to me that the MoBo RAM is set up as a hobbled replacement for the first(second?) bank of the extra SIMM and that doing away with the MoBo DRAM ICs might free up those control lines for use on the unaddressable bank of the additional SIMM?
It's still and "under the board" PCB Hack, but what the heck!?! [}
