DVD drive not recognized on first boot
Posted: Sun Sep 09, 2012 4:38 pm
now this is an odd one. my silverstone slot-loading DVD drive is never recognized by AOS on the first cold boot of my pegasos2 machine running OS4.1u5. if i do a warm reboot thereafter, everything is fine -- although i still have trouble playing DVDs on it at an acceptable frame rate, but that's another matter. here is the output of idetool -l sii3114ide.device after the (successful) reboot:
i can't seem to find anything wrong per se that would explain this, except that i know if there is a substantial pause between kickstart launch and the AmigaOS boot screen appearing, that the DVD drive will not be recognized and i'll have to warm reboot to get the driver to 'see' it.
any ideas?
