Am I the only person in the world who can't configure ide-scsi? The ide-scsi module is loaded according to lsmod and boot.msg but hdc and hdd keep on working as atapi devices. ( unless I make the hdc scd0 and hdd scd1links when they become 'unknown devices' Can anyone help, I'm desperate Peter
What does your append line look like? Did you look in /var/log/boot.msg to see if there were any errors during startup? Anders On Wednesday 29 August 2001 21.37, Peter Dixson wrote:

Hi; I had a similar problem, here's the solution I received (note if you already have a value in INITRD_MODULES just add the extra term in the quotation marks after a space): Go to /etc/rc.config and edit the variable INITRD_MODULES(or something similar). Add "ide-scsi" to the value. Save it and run after this "mk_initrd" and "lilo". Both of them must run !!! Thanks to Alexander Kern for originally providing me with this one.

Lilo needs this append line: append="hdd=ide-scsi" Don't forget to re-run Lilo. Matt

You may need parameters similar to these on your LILO append line, or manually typed at the LILO boot prompt (test them that way first): hdg=ide-scsi max_scsi_luns=8 This marks my /dev/hdg drive (in this case, a Yamaha IDE CD burner) to operate under ide-scsi. You can repeat the first part of this for multiple drives, e.g., hdg=ide-scsi hdh=ide-scsi and so on.

I had the same trouble with my ATAPI cd-writer. As far as I can make out, the problem is due to having ide-scsi compiled as module and ide-cd compiled into the kernel. The documentation says that in this case, the ide-cd code always takes precedence. The way that I resolved it was to rebuild the kernel with ide-cd support built as a module. I ran "make xconfig", selected "m" for the entries "Include IDE/ATAPI CDROM support", "SCSI emulation support", "SCSI CD-ROM support", and "SCSI generic support". You will also need to add some lines to the /etc/modules.conf file: alias scsi_hostadapter ide-scsi options ide-cd ignore=hdc (assuming your CD-RW showed up before as /dev/hdc). I've been told on this list that a kernel rebuild isn't necessary, but I haven't been able to get it to work otherwise. Once I went through the trouble, I could see the device with "cdrecord -scanbus", and it has worked well ever since. Daniel ps -- sorry if you're seeing this twice. I've been having some mailer problems.

Which documentation would that be? I've been running ide-scsi emulation for a while, and all I had to do was add hdc=ide-scsi on the append line. This is with the SuSE default kernel, and as far as I can tell, it has ide-cd built in, and not as a module Anders

The documentation I was thinking of was the configuration help text in the kernel sources: "SCSI emulation support CONFIG_BLK_DEV_IDESCSI ... If both this SCSI emulation and native ATAPI support are compiled into the kernel, the native support will be used...." (Okay, seems I was a bit off-the-mark, as it actually says this is the case when both are in the kernel.) I also read the "CD-Writing Howto", which recommends building the IDE drivers as modules and the SCSI drivers as either modules or into the kernel, if you are having trouble getting ide-scsi emulation working. In any case, I had the same trouble as Peter did and just using the append line in /etc/lilo.conf didn't help me out either. Daniel

Daniel, can I ask you if you have any genuine scsi devices on your system and if so is your cdwriter on scsi0 or scsi1? Peter
