Ok, I think I've got a handle on this. First, with the 2.4.18-686-smp kernel the "append=hdb=ide-scsi" thing doesn't work. The reason being that ide-cd is a module rather than being built into the kernel as it was with 2.2 kernels and the bf2.4 kernel that's installed by default. Next, the reason I was getting a spew of error messages with the above modutils options was that ide-cd does not like it if you tell it to ignore all of the ide devices in the system. If I gave it only one device to ignore the error messages went away. I think the reason why ide-cd was getting loaded at all was because I was calling hdparm to enable DMA (which my previous 2.2 kernel did not turn on by default) and make sure the cd-rom devices were in the best mode. So what I did was this: 1. Built a new initrd.img with just the drivers I need to boot. I put this list in /etc/mkinitrd/modules: ext3 aic7xxx Then I ran: "mkintrd -o /boot/initrd.img-2.4.18-686-smp /lib/modules/2.4.18" to build a new initial ramdisk image, followed by "lilo" to make sure lilo knew where it was. This seems to have returned everything to the initial working state I had after first upgrading to 2.4.18-686-smp. 2. In /etc/modultils/cdrw: alias ide-cd off I have no ide devices except for my cd-rom and cd-rw and I want both of them to be treated as scsi so they will show up in kreatecd. Thus I don't need ide-cd. If you have some ide devices that you want to be treated as ide, then I think you'll need to put "options ide-cd ignore=hdb" instead as suggested in the CD-Writing-HOWTO. Then run update-modules. 3. Added these modules to /etc/modules: ide-probe-mod ide-scsi The ide-probe-mod causes the two ide devices to exist as /dev/hdb and /dev/hdc so that hdparm will work, but it doesn't load any cd-rom support. Now everything works fine. The "sg" and "sr_mod" modules seem to get loaded automagically when I try to write to a cd. The rest of my settings in /etc/modutils are basically stock, except for one to load NVdriver for my NVidia card. -- -| Bob Hauck -| To Whom You Are Speaking -| http://www.haucks.org/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
