It's an old drive, granted (from the original Creative DXR2 kit), but it worked fine under FreeBSD 4.x. With 5.2-RELEASE, I reported that I was unable to mount CD-ROMs with it back in January (http://lists.freebsd.org/pipermail/freebsd-current/2004-January/018441.html). At least FreeBSD booted with it then... Note that the drive will boot the FreeBSD install CD just fine, but will not work once the kernel is loaded. Toggling DMA mode off doesn't help. I've tried different cables, but they were all rounded single-drive 80-pin cables. Perhaps I'll dig up an old regular 40-pin double-drive flat-ribbon cable and see if that works. Drive is jumpered to master. Here's the section from the booting 5.2.1-p6 dmesg: acd0: FAILURE - MODE_SENSE_BIG status=51 sensekey=ABORTED COMMAND error=4 acd0: FAILURE - MODE_SENSE_BIG status=51 sensekey=ABORTED COMMAND error=4 acd0: FAILURE - MODE_SENSE_BIG status=51 sensekey=ABORTED COMMAND error=4 acd0: DVDROM at ata0-master WDMA2 acd0: FAILURE - REQUEST_SENSE status=51 sensekey=ABORTED COMMAND error=4 acd0: FAILURE - REQUEST_SENSE status=51 sensekey=ABORTED COMMAND error=4 Jon
