Having recently upgraded my Iyonix to RISC OS 5.20 I am disappointed with its Power-on/Re-boot performance. I often have to switch off and on again to get it to Boot-up. It intermittently fails to re-boot - no beep is heard. Nothing exceptional is reported by Reporter running in Boot logging mode. I installed virgin copies of !Boot, Apps, Printing and Utilities from the ROOL HardDisc4 zip download. Can any of you bright sparks suggest what might be causing this? Reliability with RISC OS 5.18 was excellent but I would prefer not to re-install it.
