Neither iso9660 nor the device entry have to do with the probing of your CD drive. Either you make a custom kernel and comment out the appropriate line for the driver or you can configure the kernel at boot time via "UserConfig" not to probe for the device. The first way is straightforward and documented in the handbook. The second way is documented in the loader(8) manpage and e.g. here: http://www.treefort.org/~rpratt/freebsd/31/userconfig.html or for different CD-ROM drives mentioned here: http://www.freebsd.org/relnotes/5-STABLE/installation/i386/trouble.html regards Titus ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
