DVD drive not recognized on first boot

Postby eliyahu » Sun Sep 09, 2012 5:38 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? :?:

How did you setup your "nvrom.txt" in "SYS:Kickstart/"? This is mine, having an additional 3152-SATA card installed:

peg2ide_xfer=FCFF
peg2ide_irq=1111
peg2ide_maxbus=2
peg2ide_conf=1210
sii3512ide_conf=10
sii3512ide_maxbus=0
sii3512ide_xfer=FF
sii3512ide_irq=11

It works like the usual nvram variables from AmigaOnes/Sams - except that is uses a text file for holding this information. Here you can see my DVD drive as the second drive on the first ATA channel. Maybe the "automatic recognition" of your configuration doesn't work (timeout from DVD drive? ... might explain the looong Kickstart screen pause), but you might be able to tell your OS about your DVD drive through a appropiate nvram setup like this (example!):

sii3114ide_conf=1020
sii3114ide_xfer=FFCF
sii3114ide_maxbus=2
sii3114ide_irq=1111
X1000|II/G4|440ep|2000/060|2000/040|1000
