Bingo! With 2.0.34-pre13 I receieved "referenced SCB 255 not valid during selto" on every cold boot (after the cd-rom refused to do wide transfers). Pressing reset or ctrl-alt-del would allow a normal boot, but the cdrom was not detected at all. With 2.0.34-pre15+aic7xxx-5.0.15-34pre15 the normal boot returns even on power-on. The system is an Acer Pentium II with an on-board aic-7880, connected to an IBM DCAS-34330W 4G wide drive and an NEC CD-ROM DRIVE:464. If it would be useful to either of you I would be very happy to transcribe the error messages under pre13 or dmesg output from either. As the problem is completely reproducable here, I would also be glad to do any testing for you... Thank you both for your efforts! Cheers, - Bill P.S.
