Help. I have an early Iyonix without circuit board mods OS 5.11. It has always been reasonably stable until after my visit to Wakefield. I bought a DVD writer & software from APDL. That works like a dream but I now get crashes manipulating large pictures in Photodesk & Dpingscan. The computer will not reset after one of these freezes & requires a power off restart. I get the impression it freezes less often if the DVD writer IDE cable is disconected?? I have changed the IDE cable, cleaned the RAM contacts. The DVD drive is NB354OA (NEC) Voltages are no different red 5.08V yellow 12.09V. How do I test the RAM? Any suggestions? Imternet/Messenger seem to be working OK Chris -- C J Craig Chris@xxxxxxxxxxxxxxxx Castle Iyonix PC XScale Processor RiscOS 5.11. --- To alter your preferences or leave the group, visit //www.freelists.org/list/iyonix-support Other info via //www.freelists.org/webpage/iyonix-support
